By executing the following code, the WGM110 returns the event "wifi_evt_sme_wifi_is_off result: 0x0187 'Hardware failure'"
Tested on fw 1.1.1 and 1.1.1-1ae5e81f
dim power_mode event system_boot(hw, bootloader_version, major, minor, build, revision_len, revision_data) power_mode = system_power_saving_state_0 call sme_wifi_on() end event sme_wifi_is_on(result) call sme_set_password(14, "wrong_password") #set a wrong password (min 8 char) call sme_connect_ssid(10, "valid_ssid") #set a valid ssid end event sme_connect_retry(hw_interface) if(power_mode = system_power_saving_state_0) call hardware_set_soft_timer(100, 0, 1) end if end event hardware_soft_timer(handle) call system_set_max_power_saving_state(system_power_saving_state_1) end event system_power_saving_state(state) power_mode = state end
Unfortunately, we could not reproduce this hardware failure with different FW versions including some test build that was provided before. Have you taken any additional steps? Can you please let me know how I can reproduce this issue to investigate further? I attached below logs from the tests we have carried out. Have you tried to connect to a different AP? Does the problem occur every time?
I performed further tests, I tried to connect with different AP, the problem occurs in 50/80% of cases with all Access Points.
I am able to reproduce this problem with different AP from different manufacturers.
Analyzing the log you sent me I noticed that retry in your case happens very quickly.
In my case, between one retry and the next, about 20 seconds pass, perhaps it is for this reason that you cannot reproduce the problem.
Have you tried to connect with different APs?
Thank you for the detailed description. Due to the current situation, we will be able to reproduce the error on one of the listed routers within the next few days. In the meantime, to speed up the investigation process we would need over-the-air logs of the Wi-Fi communication, could you provide it? Anyway, our R&D team is currently handling the problem. As soon as we fix the issue, we will provide you a test build version or a workaround if possible.
