Issue: I can’t communicate with RAK4600.
I want to use the RUI API but I cannot send the .bin file to the RAK4600 with the Device Firmware Upgrade Tool RAK Serial Port Tool program. I have tried using the AT commands to check the serial port and I do not receive a response from the RAK4600. I have been programming the RAK4600 so far with the Segger Embedded Studio program, and I have had no problem but I would like to be able to use the RUI API.
I have updated the firmware through the SWD connection with the RAKDAP1 and the command pyocd flash -t nrf52 RAK4600_v188.8.131.52_20200925.hex successfully.
I have also tried with the Arduino environment but I am not able to establish any type of connection either.
I have followed all the RAK tutorials and I am not getting the results.
I would like to know what I am doing wrong or how to solve the problem.
