I have RAK3112 device. I was using Platform IO. I guess I accidentally erased the boot loader because of that my rak device is not recognizing through USB(showing code 43 error in windows).What the solution for this?
Welcome to the forum @homesh456babu
Try to pull the BOOT pin to GND when powering up the device, it should start up with its internal bootloader.
@beegee Thank you it worked , but do I have to do it every time while plugging to my laptop through USB?
Normally not. When flashing a firmware it should go automatically into bootloader mode.
Did you change the USB mode in platformio.ini?
No I haven’t changed anything related to USB. Now how can i reset it to normal?
If you haven’t change anything in the platformio.ini file or in the ArduinoIDE board settings, you should now be able to just flash your application on the board.
