Hi all,

We are using the WGM110 modules in access point mode. It works fine on older laptops and with TP Link USB dongle. Newer laptops (2019 onward) see the SSID of the logger but fail to connect (in windows).

Has anyone else seen this?

We are using 1.1.1 FW for the modules

Thanks,

Ross

By changing the operating mode from STA_MODE to AP_MODE. The AP_MODE turns itself off after approximately 105 seconds...

Tested on FW 1.1.1 and 1.1.1-bc205f19

dim operating_mode

event system_boot(hw, bootloader_version, major, minor, build, revision_len, revision_data)
	operating_mode = 1
	call sme_wifi_on()
end

event sme_wifi_is_on(result)
	if(operating_mode = 1)
		call sme_set_password(8, "12345678") #set a valid password
		call sme_connect_ssid(12, "Tenda_84C700") #set an existing SSID
	end if
	
	if(operating_mode = 2)
		call sme_set_ap_password(8, "87654321")
		call sme_start_ap_mode(1, 0, 6, "WGM110")
	end if
end

event sme_interface_status(hw_interface, status)
	if(status = 1 && operating_mode = 1)
		call sme_set_operating_mode(2) #set AP_MODE
		operating_mode = 2
		call sme_wifi_off()
	end if
end

event sme_wifi_is_off(result)
	call sme_wifi_on()
end

I have a full development WGM160P board and we do pushes to it mostly via Gecko OS IDE and then through Zentri updates using OTA enabled settings.  We then call a dfu_update on the device after we release a bundle.

For some reason we are getting the device into a weird state after it's running.  Here's the error.

SAVEMODE> Starting Safemode console for 300 seconds.
Issue 'faults_reset' then 'reboot' to exit safemode.

So far, after that we must connect it to a PC with USB.

Is this only because we are pushing via Gecko OS IDE?

after I run those two commands (connected via computer), the device resets fine and runs our code and connects to the internet fine.

We're wanting to test some things completely unattended and always run Zentri commands or is this just an issue with just using Development Builds?  I haven't tried a Production Build via Zentri.

the system.uuid is:   EADE2FF3BF69FCAD93D8518ECCCCCCFFFE2F88D1

I was going to test with just using Gecko OS Studio -> Program Device -> Mode -> Products -> <Select Product> only, but not sure if that's a better solution to prevent the issue.

With the Tenda N301 and Tenda F3 routers in power_saving_state_1 the WGM110 doesn't connect.

Hi, 

I turn on setup web on amw037 module, softap static ip is 10.10.10.1 but when client connect to this AP, it receives IP 192.168.4.x. I can not find any variables to disable this dhcp ip range. I want it connect to 10.10.10.1 network.

Could you give me the solution ?

 

Another problem. Sometime I receive ip 10.10.10.x but setup web urt not work.

Hello,

I am using WGM160 module, I have compiled the firmware but have some troubles with authentication.

Should i enable SL_WFX_SLK_CURVE25519 flag in the project. It is used in sl_wfx_host_verify_pub_key function for instance.

I have some problems with it.

Thanks,

I am designing a high speed WIFI transmission device.  The WF200 datasheet surgestes to use 38.4M crystal without any parameter spec.  However it is in the user manual it surgestes  oscillator.  Is it still support  crystal?  And what is the matching parameters?  Thanks

When there is error in data transfer, how should I handle the abort operations? Per the SDIO specifications, we can use CMD52 to write to CCCR to stop the data path. Is this neccessary for WF200? What's the recommended way with WF200?

 

Thanks.

If I try to run the "ping test.local" command from the Windows command prompt the DNS is not resolved.
But if I set the WGM110 in power_0 mode, the ping works.

If before the system_reset command I print something over the UART abnormal behavior occurs

With firmware 1.1.1, only the sixth endpoint_send command works correctly, and with firmware 1.1.1-c3c999f3 the endpoint_send command never seems to work, also with firmware 1.1.1-c3c999f3 BGTool does not display the event wifi_evt_system_boot

export const UART0_ENDPOINT = 0

event system_boot(hw, bootloader_version, major, minor, build, revision_len, revision_data)
	call hardware_set_soft_timer(10000, 0, 1)
end

	call endpoint_send(UART0_ENDPOINT, 10, "HARD_RESET")	#doesn't work
	call endpoint_send(UART0_ENDPOINT, 10, "HARD_RESET")	#doesn't work
	call endpoint_send(UART0_ENDPOINT, 10, "HARD_RESET")	#doesn't work
	call endpoint_send(UART0_ENDPOINT, 10, "HARD_RESET")	#it works partially

Hi,

We working on a new project and are developing using the WFM200S Expansion Kit. We could not get access to the Interposer board suggested for the connection between the STM dev boards and the WFM Expansion kit. So we proceeded with using jumpers for interconnection instead.

- We are using the "STM32F429ZI based Bare Metal example" provided in WFM200S Expansion Kit documentation for our application.
Our board is the STM32L4R5ZI, we are using the SPI_MOSI, SPI_MISO, SPI_SCK, SPI_IRQ, SPI_CS, SPI_IRQ, GPIO_Wakeup and RESET pins in the SLEXP8023A(WFM200S Expansion Kit) from the EXP Header.

- We need more clarity on how to power the board, which pins to use when the switch is in onboard LDO mode and which ones to use when in VMCU mode.

- We have included the FMAC driver and the LwIP library in the project built using the STM Cube IDE. We are facing issues during the chip initialization process.

- Please find below the flow to the point of error.
->sl_lwip_init ->sl_wfx_init ->sl_wfx_init_bus ->sl_wfx_host_init_bus ->
ERROR in this line,
->status = sl_wfx_reg_read_32(SL_WFX_CONFIG_REG_ID, &value32); (line:93; sl_wfx_bus_spi.c)

- We believe "sl_wfx_reg_read_32(SL_WFX_CONFIG_REG_ID, &value32)" is causing issues. The value of "value32" is still 0 after this line's execution and because of that, we are getting SL_STATUS_FAIL. We need suggestions on how to solve this problem.

Also, it would be great if you could share the schematic of the Interposer board suggested for the connection between the STM dev boards and the WFM Expansion kit. No information about this interposer board is available online for reference.

Kindly help us in this regard, this is a very urgent requirement.

Hi,

We have a SoftAP TCP server running since early this year, Just recently we tried connecting a Windows 10 PC and we are not able to connect to the SoftAP.

Android phones and tablets still could connect. Anyone running into the same problem or has any idea what to do?

By running the following code the tcp server starts only the first time, the second time the error "result: 0x0208 'Address in use'" is returned "

We are developing a WiFi chronothermostat (https://www.sitecdomus.it/cronotermostato-domus/), with a temperature sensor to detect the room temperature (home).

We have found that the WGM110 heats up a lot in power_mode_0, and this is a problem for the temperature sensor that detects too high temperatures.
We solved this problem by setting the WGM110 in power_mode_1, in this mode the WGM110 does not heat up much, allowing us to detect the correct room temperature.

But in power_mode_1 the embedded UDP server of WGM110 is not working properly, in particular, many UDP frames sent to the broadcast IP address are lost, but if I send the same UDP frame directly to the IP address of the chronothermostat (WGM110) everything works correctly.
