Dear Forum, 

In my application the AMW007 is used as wireless serial port.

Do I need to make the module auto join the network and auto connect the TCP server?

I could bring up the network manually and connect manually. Then call EXIT to return to STREAM mode (If the STREAM mode has been set with a save/reboot command previously)?

Do I need to make a SAVE/REBOOT when I have changed the SSID, IP's etc?

I would rather not use auto connect because I need to check the presence of the AMW007 module each time I start up.

So it would be easiere just to setup the WLAN and TCP Client every time my application startsup, instead of first check the current setting before I change them.

I don't normally use BGScript for anything in my application except reporting a firmware build number, so despite the hundreds of hours I've spent working with this thing I don't have much experience with the scripting and I don't see an answer to this in the docs.

If I use cmd_hardware_set_soft_timer to set the interval of an existing soft timer, is the timer reset or does it continue from where it was?  What about if the timer is disabled by setting the interval to 0?

My idea is to create a watchdog timer to monitor the connection to the host.  The script would start the soft timer during the boot event, as a one-shot with an interval of maybe 12 seconds, and the host would send the module a timer reset command every 10 seconds.  If the timer expired without being reset, the script would fire off a syslog message to an IP address stored in the persistent store and then reset.

That brings me to another question:  Is the WGM110's reset line strictly input only?  I know it doesn't reset my host when a software reset command is issued.  Can it be configured to assert an external reset so as to reset the host processor as well?  Some of the MCUs I use have their reset lines on multiplexed pins that can be assigned to a GPIO and controlled directly, but I don't know much about the Giant Gecko in the WGM110 and I can't seem to find the part number right now.

That part's not as important, since the host has its own watchdog timer and is presumably in bigger trouble if it hasn't come back already.  The important part is just to get a log notification to distinguish a failed host from a network problem.

Thanks,

Scott

We have about 35 units deployed and many are having issues when our customer tries to fill in low signal areas with additional hotspots with the same SSID as what is programmed into the WF121. The failure occurs pretty much every day and the fix is to power cycle each unit once a day. The issue is that the modules are not staying connected to the closer hotspot, but at some point each day, they connect to another hotspot further away and then stop communicating with the network until they are power cycled. This product line is several years old now and the problem has been with us all along, but now the customer wants to place an order for more units and wants a fix for this issue.

The scripts were compiled with wf121-1.4.0-88. Much of the script was developed by Bluegiga tech support people who helped us out a lot during development of this product. Please let me know if there is any additional information you need.

Hi there,
We're building our first batch of PCBs with AMW007 in them.  In one of the boards, one Zentri is not coming up in Factory Reset Mode, and I know this because you don't see the Zentri Web Os XXX SoftAP created.  When I scope it, I notice that the UART_CTS line is not stable 0, but instead toggling like a UART communication.  And then I found that this toggling is exactly the same with GPIO_2 which is the DEBUG_UART_TX.  See picture below.  And this is happening when I don't expect to TX/RX anything in the UART.

 We're trying to decide if this is an issue with the assembly or the issue with the Zentri, or if the Zentri is actually coming up in a different mode than Factory Setup.  I've checked that there is no short between GPIO_2 & GPIO_6 as far as the assembly is concerned.

Is there some sort of Debug mode in Zentri where the GPIO_6 is doing this?  Especially because in the Datasheet this GPIO_6 is called DEBUG_UART_TX, so I wonder if it's actually in some sort of DEBUG mode.  But, I can't find other info about what it means with DEBUG UART TX.

 

Hi,

I'm thinking on using the WGM110 module for an application. In my application I would like to store data in the module flash memory, and send these data to a server occasionally. Imagine a "connections.txt" file which contains the number of connections with the module. Can its content be modified every time I connect with the module? My question is if this is possible, because I've been watching examples in the SDK and all the binary files flashed into the module have a size of 1 MB, so they occupy the whole memory of the module. Thus I don't know if you can change a file which has been used for built the project after having flashed it to the module.

And another doubt. Is the WGM110 able to work as a Wi-Fi Direct Group Owner and being connected to the Internet at the same time?

Thanks.

Hi,

I am using WGM110 with STM32F4 interfaced via UART with BGAPI.  WGM110 has v1.1.1 firmware.  In the endless loop below, gethostbyname will fail with 640 and never recover about 30% of the time with in the first five minutes of running.  At other times, the loop will run continuously for hours with out encountering the error.  Is there a way to reset the DNS cache?

The level of detail in the various versions of BLUEGIGA WI-FI SOFTWARE API DOCUMENTATION leaves a lot to be desired, particularly for the binary access to commands & responses & events.  I am developing a WF121A-based device for a WiFi AP for real-time data acquisition utilizing streaming data via serial ports.  The documentation indicates the Configure-TCP-WiFi command has a "minimum" payload length of 13 bytes.  Is it ever bigger?  I presume it knows where to find the data in a larger redundant message but am I correct?  When I retrieve PS key 2 (the IPv4 settings) the PS Load-Flash-WiFi response message clearly indicates the key data value is sixteen bytes long (second byte payload length is nineteen, first byte of key value array indicating key value length is sixteen).  What exactly is in the key value message?  Where do I get PS key syntax information?  Much of the binary user programming requires access through the pre-defined PS keys but nowhere in the BLUEGIGA WI-FI SOFTWARE API DOCUMENTATION  is there any detail as to the format of these 59 keys.  Is there another guide with more detail?  How is a developer supposed to know how to use the pre-assigned PS keys?  The guide is otherwise quite comprehensive.  Most keys are self-explanatory, but this inconsistency regarding PS key 2 tripped me up.  Other commands indicate when critical key values are involved but Configure-TCP-WiFi does not.  Once again, it's fairly self-explanatory but syntax detail is lacking

Could you tell me how to get the RoHS certificate including not only six banned substances but also four phthalates (DEHP, BBP, DBP, DIBP)?

Our search did not match any documents containing “Phthalates” in your search engine. 

I'd like to use the ADC peripheral in a design but I see no support for the ADC in ZentriOS-WL.  What do I need to do to use the ADC in the AMW007?

Hello everyone,

I have a custom PCB using WF111 module on Linux. I'm measuring the output power from the module and getting less than 6dBm, such value doesn't match with the value according the datasheet (16dBm).

I would like to know how can I control the output power from the module, given that the drivers does not implement/support all the commands from iwconfig, that would make it possible.

thanks in advance.

Hi 

  Asking this question since it is still a bit unclear on how to exit streaming mode. I have the WGM110 connected via UART (via WSTK) to a host PC and am able to start a TCP client (endpoint 1) and connect to an external TCP server. I also redirect the output to the UART  (endpoint 0) so I can monitor the replies from server. As long as the UART pipe in in BGAPI mode, sending and receiving data in chunks of less than 256 bytes wrapped in BGAPI protocol seems to be fine. However, when I set the UART (endpoint 0) to streaming mode for a raw data pipe to the tcp server (external), then I am unable to exit that and recover control of the module through any BGAPI protocol command. What is the mechanism to reset the endpoint 0 (UART) to BGAPI mode ?

Thanks

Hugh

Hi,

I'm trying to use the WF 121 and am a little confused about what using USB in streaming mode. The WIFI BGSCRIPT guide states that if the USB is used in streaming mode  that the data is discarded. Does that mean that if it's connected in USB mode the module can only transmit data?

Thank you

I am trying to send GET request to AMW037 functioning as HTTP server. I can load static web pages in its external flash and access them via computer browser. My goal is to establish a kind of dynamic web page. Namely, pass some data to the server with a GET request (for example, request air temperature measured by sensor handled by external CPU)), forward this request data to external CPU for processing and composing HTTP response, and send this response back to the HTTP client (computer browser). Is it possible?

What is the proper way to close a listening socket (TCP server in BGAPI parlance)?  It gives a 'wrong state' response if you try to close it while clients are connected.  I can close the client connections first, but one popular client program I'm testing with retries the connection as soon as it drops and the result is that I can't reliably shut down the listener on the WGM110 fast enough to keep it from reconnecting.  How do I stop it from accepting new connections AND get rid of all existing connections, when clients are trying to reconnect as fast as they're dropped?

<rant>Documentation feedback doesn't seem to go anywhere, but I'm going to throw some in here anyway.  It's been well over two years since the WGM110 was released and the API reference manual still doesn't even directly describe the process of establishing a TCP connection - it's left to the user to figure out what sequence of events results from a connection.  And listeners are even less documented.  There's nothing in the documentation to even suggest that endpoint_close is the way to stop a TCP server.  I've been operating under the assumption that the functions are mostly a wrapper for the Berkeley Sockets API and that's generally a good start, but even that much isn't stated in the manual.  Yes, there are examples, but as I've pointed out before, the examples frequently don't check for important failure responses, or may not do any error checking at all.  They're far from exhaustive resources.</rant>

Thanks,

Scott

Hi All, 

we are working a product development and we are trying to use the WGM 110 chip , we have bought the chip and wired the spi and SWD connections .

Now can someone please help /guide to setup the work environment on either simpilicity /IAR ide so that we can write the program and flash it to the WGM110 .

Note : we are not using the Wizard Gecko Wireless Starter Kit. 

Appreciate for all the help and guidance in advance.

Best Regards
