Hi I have two Lilygo TTGO T-Beam boards that came with Meshtastic installed.
When I used the Meshtastic software to connect to the boards it told me that the software needed to be updated and so I did this over the USB port.
Both boards were working well and then I decided to try using Arduino IDE to program one of them. I used the Blinky sketch which flashes the onboard LED.
After doing this the display on the board remained off and the red LED was constantly on.
I couldn’t connect to the board anymore and tried the Meshtastic-Flasher but it wouldn’t connect.
I tried a USB to serial device and nothing recognised the board. I could see the following text over the serial port when I pressed the reset button:

I guess the board is working and needs a fresh reflash but how as nothing seems to be able to communicate with the board.
