I’ve bought 3 TTGO T-Beam V1.0
At the begining, blue LED was on while plugged on USB or with a battery.
Now, 2/3 devices don’t have the LED on anymore
They are working, just no sign at all.
Samething with the flashing red LED, doesn’t flash anymore.
It is hard to guess if the radio still powered, or is it my bluetooth connection that is failing.
Is it a common problem ?
