We are having troubles with the data rate available with the module WF111.

Using iperf3, we get :

  14.5 Mbits/sec in download

  5.31 Mbits/sec in upload

The data rate in download is somewhat consistent with the answer given to that question.

Is the upload data rate normal ?

In this question the access point configuration seems slower. Is it true ?

We use the driver version 5.2.2-r4 for armv7 with a Linux kernel 4.9.11 on iMx6

When doing the test, signal quality was rated 69/70 from the testing device.

I already checked the document "WF111 Troubleshooting" (UG220.pdf)

Best regards

 

 

In my app I start an MQTT connection with my local eclipse-mosquitto broker installed on QNAP NAS

MQTT connection cfg

gos_mqtt_configuration_t mqtt_cfg =
  {
    .mqtt_version       = MQTT_VERSION_3_1_1,
    
    .use_tls            = false, 
    .use_secure_element = false, 
    .clean_session      = true,
    .automatic_reconnect= false,
    
    .network_interface  = GOS_INTERFACE_WLAN,

    .keep_alive_interval_seconds = 10,

    .broker_port        = 1883,
    .tx_buffer_size     = 1024,
    .rx_buffer_size     = 1024,

    .broker_hostname    = "192.168.1.68",
    .client_id          = "fraelacco",

    .username           = "" ,
    .password           = ""
  };

automatic_reconnect is set to false

My app publish every 10sec it status For testing broker disconnection I shut down randomly  the broker

In this case the device log is

Got a batch of new AMW006 boards with FW 2.3.2 I would like to claim and update.

I was unable to get it working at my Workplace so brought it home, factory reset the device, connected to my home wifi network, and tried again, but still not working. 

Below is what i get. Please note 'MYSSID' , USERNAME and PASSWORD in bold font actually had my actual router SSID, my correct username and passwords.

I used the similar approach for AMW006 devices i obtained earlier this year with no issues.

For setting up, i use the Marlin AAE001.4 board .  

I also notice that with these new batches of AMW006 devices, when the device is connected to the network, both the middle yellow led  and the green leds flash slowly unlike the previous batch i had where only the middle yellow led flashes slowly.

I updated to the following firmware:

SILABS-WGM160P-4.1.11, Gecko_OS-STANDARD-4.1.11, WGM160P

I am following the example here:

https://docs.silabs.com/gecko-os/4/standard/latest/cmd/apps/highspeed-uart

My setup is using the WGM160p in softAP mode and it is running a TCP server. 

I am connecting to the WGM160p via a TCP client on a separate PC.  I am writing a 300KB file to the WGM160p via UART0 (with flow control) and receiving this data via the TCP client on the separate PC. I am not getting the 615.221KB/s (About 5Mbps) as per the example in the link above.  I am getting rates of maybe 0.5Mbps to 1Mbps with a UART0 baud rate of 8000000 bps.

Is there any configuration using the  Gecko Commands per the example above that might help increase the rate?  Any suggested size of writes to the UART0?  256 or 1460 Bytes?  I am stuck.  I also see occasional delays of seconds in the 300KB continuous transfer for some reason as well.

Thanks!

Is there a way to control what the version number is for a bundle in Zentri DMS?

By default the first bundle is 0.0.1, next is 0.0.2.  I haven't experimented more to determine how to use the first two digits.  

Hi,

I'm trying to program the mcu on the WF121 to connect to a particular network by its BSSID, however I am confused by the hw_addr data type in the documentation. How would I call wifi_cmd_sme_connect_bssid with the BSSID of 00:07:80: 1A:2B:3C, for example? 

Thanks!

Hello Team,

We are developing a custom wi-fi enabled portable solution based on WF200.

We are considering WGM160p as a reference for hardware design (WGM160 Datasheet page no.6).

The controller part number used in our design is EFM32GG11B840F1024GM64-B.

We do not want to use the Gecko OS , IDE for our development, Instead would like to implement a custom RTOS based solution.

I got the link for the driver file for WF200 (https://github.com/SiliconLabs/wfx-fullMAC-driver).

Hope this driver works.  

I need the following information to start my hardware and firmware development with WGM160P:

• Can we completely erase the WGM160P Gecko OS and start working with firmware development on simplicity studio?

I have a SLWSTK6121A kit, I stacked up the WGM160P on it and tried to flash\unlock the module using the simplicity commander of simplicity studio. It shows flash erase success but still I was not able to establish any debug session using a simple led blink code of SLSTK3701A.

(I thought this is closest device to the WGM160P controller.)

Please let me know what needs to be done to erase the Gecko OS and debug WGM160P using simplicity studio.  

• The driver @ link , https://github.com/SiliconLabs/wfx-fullMAC-driver is tested ?
• Where can I get the schematic of WGM160P to refer for my hardware design?

 

Regards,

Santosh 

 

Hi, 
I'm working on a project using WGM160P Wi-Fi Module Radio Board (SLWRB4321A) and Gecko OS. I used Wireless starter kit mainboard to program WGM160P Wi-Fi Module Radio Board using Gecko OS IDE for my initial testing. 
Now I want to develop a prototype using WGM160P bare module. So, I just want to know how can I program WGM160P bare module using a Wireless starter kit mainboard and Gecko OS IDE? 
What are the physical pin connections should I do between wireless starter kit and WGM160P bare module? 

Thanks,
Harsha

I'm currently using the WGM160P Wi-Fi Module Starter Kit to validate that we can use the WGM160P module to add WiFi support to a project. On the final project, we will have a  bare WGM160P module connected to the host MCU only by the serial port, and the host MCU will use the Gecko OS Command API. As far as I understand, new WGM160P modules came with Gecko OS Kernel only, don't have support for the Command API, am I right? In this case, how should I upgrade them for the full Gecko OS version during the production phase?

Best regards

Fernando

hi,

    After power on i give set sy s t 5 command for sleep 5 seconds, and the give save ,reboot command.
   After rebooting module i got 

ZENTRI-AMW037-1.5.0.13, 2018-09-03T06:14:28Z, ZentriOS-WL-1.5.0.13, Board:N/A
[Ready]

but it is not taking any commands.

how to come out from this sleep command.

thank you

With WGM160P it is possible create this:

open a listening tcp server socket on port X that permit accessing device data with determinate protocol (e.g. tcp-modbus on port 502)

open a second listening tcp server socket on port Y that permit accessing device data with another protocol (e.g. return device data values in a json string)

I tried this

 gos_tcp_register_server_event_handlers(tcp_client_connect_handler,
                                        tcp_client_disconnect_handler,
                                        tcp_client_receive_handler);

 gos_tcp_listen(GOS_INTERFACE_WLAN,MBUS_TCP_SERVER_DEFAULT_PORT) ;
 gos_tcp_listen(GOS_INTERFACE_WLAN,10000) ;

but only the second port (10000) is available ;

I could solve with a configuration procedure that selects the protocol and the port to use but I would like to do something to use to use without configuration

Next question

reading client info with gos_tcp_get_client_info called from tcp_client_connect_handler returns always local_ port = 0

 

Hi, I bought the AMW136-E03 Mola evaluation board recently because I wanted to perform some ADC but just realised that it does not support ZentriOS SDK but only command API. Is there any other way I can program the ADCs on the AMW136? Thank you.

Hello,

I am trying to communicate with a WF121 chip using the bluegiga WF121 gui. However after attaching to the correct com port, when I clicked retrieve info, the different views in the sidebar did not populate with the device or network information. I was also unable to push the "Turn WiFi On" button in the network view. I tried connecting two ways, once via a USB to TTL converter and once using a USB to FT232R breakout board, on both the UART1 and UART2 pins. After this all failed, I switched out the WF121 chip on my breakout board. Now after attaching to the com port, I am unable to even click retrieve info. I am not sure if it's an issue with my USB connection, my breakout board, or my chip (ie incorrect firmware), so if you have any suggestions on what to try next, I'd greatly appreciate it!

I have also attached a picture of my setup (where I'm using a USB to TTL converter (green is TX, white is RX) connected to Pad 35 and Pad 36 on the WF121 respectively), my breakout layout, and the integrated library I used in Altium to make the breakout.

Thanks!

Hi all,

I´m currently trying to connect a smartphone to the AMW006 TCP server. But sometimes the socket connection fails and after that, it´s not even possible to reconnect the phone to the access point of the AMW006. The error code on my phone is  ECONNREFUSED (Connection refused). If I disable the wifi on my phone the status leds of the AMW006 indicate, that there is still a connection (all leds blink slowly).

My current setup is:

set tcp.keepalive.enabled 1
set tcp.keepalive.initial_timeout 5
set tcp.keepalive.retry_count 5
set tcp.keepalive.retry_timeout 1
set tcp.server.auto_interface softap
set tcp.server.auto_start 1
set tcp.server.max_clients 1
set tcp.server.idle_timeout 120
set tcp.server.port 3000

I´m using stream mode and the version ZENTRI-AMW006-3.6.3.0, 2018-09-13T04:57:09Z, ZentriOS-W-3.6.3.0, Board:AMW006-A1W.2.
 

Thanks for your help
