Wifi beacon missing after firmware upgrade

I received the Maix Dock with factory firmware MicroPython v0.4.0-87-g42e92b235-dirty on 2019-11-07; Sipeed_M1 with kendryte-k210, when the board was powered on it will show ESP_4xxx in the list and I could connect to it and do a PING from the connected to the ESP access point

I downloaded maixpy_v0.5.0_12_g284ce83.bin and flashed the board,

Now the version is MicroPython v0.5.0-12-g284ce83 on 2019-12-31; Sipeed_M1 with kendryte-k210

However the Wifi beacon is no longer appearing on Wifi scans. How to get it back?


you need check the wifi EN pins status right? maybe v0.5 change the EN stat
