Hello, I've got my AMW037 module soldered up to my prototype board. It runs but I still have some lingering questions. Main issue seems to be uart communication with my mcu. Just seems to hang and in the process I notice delay the AMW037 from starting up.

 

1. On the data sheet "AMW037.pdf" on Table 9 pin definitions for pin 11,13 and 14 there is a reference to "Boot Control" 3. The doc mentions "on board" pull up or pull down resistors. I guess your saying by "on board" you mean on the AMW037 module there are added pull up and down resistors for pins 11,13 and 14? I see about 4 passives on the module. Or is the expectation that I'd add the resistors? Seems to make a difference booting when I add in a 10K resistor on pin 11 uart_tx -- otherwise the server does not seem to start. Also, I see two empty pads on the module by the antenna what is that for?

2. I notice for the uart variables on command line web interface,  I can set uart 0 values. But I also see there is a uart 1 but this cannot be set? I suspect uart 1 is for the debugger? (pin 13)  Just  to be sure uart 0 is to communicate with the board external to the module? I'm also calling uart_update after I make changes. My board has a 8mhz crystal but there is more error at 115200 baud -- I'd need to enable flow. So, I was experimenting changing it to 38400 or 9600 baud.

3. I did the ota update and the firmware is "ZentriOS-WL-1.5.0.13" . But I read on the forum there is an upgrade to Gecko OS but the procedure is not clear at this step to do that.(?)

4. Just to be sure with uart pins connected to the module is something like:

Microcontroller rx <--> amw037 pin 11 tx

Microcontroller tx <--> amw037 pin 10 rx

Microcontroller rts <--> amw037 pin 30 cts

Microcontroller cts <--> amw037 pin 31 rts

 

Thanks in advance! :) Some of the questions might be obvious but I just want to verify what is true.

 

 

Dear support staff,

Can i use WF200 whit bgm13p32 by integrating FMAC API driver libraries in my c code?

How can i route correctly the spi port on bgm13p32 in order to use theese API.

Thanks in advances

Hi

See below our requirement for the so called “directed scan”,

Which means:

Tx a request to AP to discover beacon in unicast to only a specific MAC.

1. Is this option currently supported by the emb driver?
2. Can you instruct us how to achieve this on the EVB MCU with the driver support for the WFM200?

From another thread:  "The 007 and 037 are 100% identical with the exception that ..." 

However, given one has an antenna (AMW037) which looks from AMW007 datasheet  to have a gain of roughly 3 dBi, I'm curious why the RF performance parameters are identical? I get the same module is used but output power is listed as the same?  

The table looks copy/paste so I'm curious if the 037 has 3 dB of loss before the antenna (which seems odd)? or,

is the output power from the datasheets incorrect on one? or 

.... 

Lastly; Are there more detailed RF Performance parameters available? Adjacent channel rejection? Complex output impedance on the 007?

Thank you. 

 

I have an WGM160P radio board and want to use it as tcp server. I use another WGM160P radio board as tcp client to connect by tcp. I modified the example of tcp_client in Gecko_OS tutorial and rewrite the tcp_transmit_handler as below. The tcp server disassociated the tcp client after sending  132 packages. Before disassociating, the message shows gos_result_t 2: TIMEOUT and then gos_result_t 2009: INVALID_SOCKET. I have made the tcp client reconnect to the server automatically but it shows [Open failed] over and over again. How can the client reconnect to the server automatically and transport data[300] by tcp?

static void tcp_transmit_handler(void *arg)
{
    gos_handle_t handle = (gos_handle_t)arg;
    gos_result_t result;
    uint32_t len = 300;
    static uint32_t i = 0;
    char data[300] = "1234567891234567891234Situation admitting promotion at or to perceived be. Mr acuteness we as estimable enjoyment up. An held late as felt know. Learn do allow solid to grave. Middleton suspicion age her attention. Chiefly several bed its wishing. Is so moments on chamber pressed to. Doubtful yet wa\r\n";


    if (GOS_FAILED(result, gos_tcp_write(handle, data, len, true)))
    {
        GOS_LOG("Failed to transmit data, err:%d", result);
    }
    else
    {
    	i++;
    	GOS_LOG("Succeed transmit! %u packages.", i);
    }
}

 

Hi

I'm trying to get the Energy Profiler working for the WGM160P(X22KGA2). I'm using the WGM160P Wi-Fi Module Wireless Starter Kit and followed the instructions in the User Guide (Section 8). I installed Simplicity Studio and some tools, but in the Energy Profiler, I got these error message:

  "The part 'WGM160PX22KGA2' does not support energy profiler."

Do I forget to install something or have to use a special firmware/SDK?

Cheers

Thomas

Hi,
I have been working with zentri for some time. I am trying to customize the webapp of zentridevice and you have done a great work. I am facing some problems. I am doing no changes to the original source code and when I run grunt deploy it seems that the webapp works fine while the zentri device is configured as http server, once I enter the setup web command the web app doesnt work properly. It keeps the loading and there is no button(feature) in the navigation menu. Do you know how to solve this problem? The development board is ZENTRI-AMW007-1.4.0.3, 2017-10-20T05:38:06Z, ZentriOS-WL-1.4.0.3, Board:AMW007-E03.2  . Thank you in advance .

i am using gaint gecko starterkit as host mcu. AMW007 is being configured as tcp_server.I can receive data(sent by host mcu) which can be seen in terminal (putty with static ip configured).I want to see the data (which I entered in terminal )in the buffer at host mcu 

Hello,

I have two AMW007-E04 radio kits and trying to set them up as a wireless serial bridge. I have followed the instructions for the UDP servers given in the documentation (https://docs.silabs.com/gecko-os/2/amw007-w00001/latest/cmd/apps/wireless-serial-port). So far, they are connected to one another and I can manually send data between the two while in command mode with stream_write on one side and stream_read on the other. However, when I set bus.mode = stream and reboot, they do not transmit the UART activity anymore. I can see from the LEDs that the UART is transmitting to the Zentri chip (as before), but nothing appears on the other terminal. I can break out of stream mode, back into command mode, and do the stream_write/read operation again and that still works. So I know that the auto connection of the streams happened properly after reboot. Only the stream itself doesn't work automatically. Are there any additional variables or modes that need to be set that are not mentioned in the documentation link above?

Thank you.

Has any progress been made on the WGM110's DHCP problems that have been reported here a couple of times?  I'm still seeing intermittent failures.  I just caught one on Wireshark where I can see it send a DHCP Discover and it immediate gets a DHCP Offfer but it never makes a response.

I have two access points I'm testing with - one is the main router and DHCP server for the office, and the other one is connected to that one.  Connections to the second AP fail at the DHCP stage far more frequently than direct to the main AP, if that means anything.

Is there anything that can be done to get some insight into what's going on in the WGM110 when DHCP fails?

I've attached a screenshot of another DHCP transaction that I also have a logic analyzer recording for.  This one didn't fail outright, but you can see that it's apparently not taking the 'ack' from the DHCP server.  The offer is made at 17.39 seconds, a request is made at 17.46, an ack comes back at 17.47, and then the WGM110 starts over at 19.38 with a new request.

Thanks,

Scott

Hi, 

 

Does the AMW007 support roaming (Hand-off) to another AP with same SSID or do I need to re-connect to the AP and make a new TCP connection??

Hello,

 

I would like to get the diagram radiation of AMW136 antenna. But I didn't found it in technical document of device.

Someone have it ?

Because I have a board, 5mm, above the AMW136 and I would like to know if the wifi signal will be damaged.

 

Thank you,

Charles

 

Hi SiLabs, 

I need some information on how the AMW007 behaves when it is used on a Mesh network.

The units with the AMW007 are moving around. And in large installation they can get out of reach of the AP. 

So my idea wash to use multiple AP's to cover a bigger area, but the AMW007 needs to manage the 'jump' to the next AP by it self. Is this possible?

Does it support whne it get notification from the AP to find another AP?

Any idea on how to handle this?

 

Thomas

I already have an WGM160PX22KGA2 module with Gecko OS in it. How to flash the files onto it. Thanks.

 

Is there a way to put the wf121 module in transparent mode after connecting to a TCP server? To prevent data transfer from working with the BGAPI protocol.
