RE: nRF70 Wi-Fi BLE Image Transfer Demo – Camera power modification causes Serial Terminal input failure in STA mode

Hi,

[quote user=""]

However, when I switch to STA mode and try to input Wi-Fi connection commands in the Serial Terminal (nRF Connect for Desktop), my command line no longer works — I cannot type any input.

I did not change anything in prj.conf.
I suspect the issue is related to powering the board through P22 jumper.

I believe your line of thought is correct. The reason why it will not work in this setup, is because the debugger IC, running the USB/UART bridge, is running on 1.8V. This creates a mismatch when your device runs on 3.3V

If your apply 3.3V to the pin "VIO REF" on pin header P22, this should also power the debugger IC at 3.3V:

Could you try this?

Kind regards,
