Configure Wi-Fi Scanning for networks never completed

[tonyjobson]

Hi, I just took a fresh ESP32 Trinity out of the box. The flash tool found it and paired to it and installed the firmware but the Scan button never finds any wifi networks. I can connect to the serial and reset the device and see the device complain at lack of wifi and timezone settings.

Unsure if i got a bad device or this is a firmware bug. Can i run an older version?

Can i set the WIFI AP and Password via the console?

I tried Mario clock and PacMan face so far. same behaviour and i've flashed each a few times.

tried two USB cables in case it was a power issue on different USB ports on my laptop.

OK. I managed to get it past this by powering the trinity with an external power supply. looks like the board may have been very powe hungry...

That's right. You need an external power supply of 3 amps or more. It's not the board, but the led matrix that consumes all that power.
