I have a RAK8211-NB and J-LINK emulator both from RAK.
I tried to follow the guides to use Arduino IDE and flash the NORDIC52832 both with J-LINK and the UART to serial adapter provided, without success.
The schematics provided seems different from what I can see in the device I own (eg. pinout on the device P1-P4 seems to be inverted).
Can you provide detail information on how to proceed to flash the device and also instructions about the wiring with J-LINK and the breakout USB-UART board? What about the jumpers you provided in the package?
Are they necessary to flash the device?
I would like to start with a simple example and then I would like to try to send AT commands to the BC95-G.
Can anyone help?
Yes, these jumpers are quite intriguing. I would also like to know if they should be used for something.
