I have a stability problem with the internal Wifi adapter of an Axon M565 LTE. I am using original Raspbian image from your download section, updated to the latest version.
Wifi works correctly for some time, going from some hours to some days then disconnect. Once disconnected, I am unable to get it back to work except with a cold reboot.
I put a temporary network cable to check logs and dmesg, here is what I noticed:
[32819.275600] brcmfmac: brcmf_do_escan: error (-110)
[32819.275650] brcmfmac: brcmf_cfg80211_scan: scan error (-110)
[32819.787535] brcmfmac: brcmf_fil_cmd_data: bus is down. we have nothing to do.
I tried to rmmod/modprobe the brcmfmac module, but I only get some more errors in return:
[32870.984472] brcmfmac: brcmf_sdio_bus_rxctl: resumed on timeout
[32870.984529] brcmfmac: brcmf_c_preinit_dcmds: Retreiving cur_etheraddr failed, -110
[32870.984558] brcmfmac: brcmf_bus_started: failed: -110
[32870.984601] brcmfmac: brcmf_sdio_firmware_callback: dongle is not responding
Am I the only one to have that problem ? Some searches on the web return me a lot of people having that problem but not on Axon controllers. Mainly on RPi 3. Is the Wifi adapter similar in the RPi3 and in the Axon ?
Any help would be highly appreciated.
