I want to install the nRF52840 firmware on my RAK4631 module with Arduino BSP and LoRa US95, but I don’t know how. I have the RAKDAP1 and I followed the instructions in the RAKDAP1 guide on the RAK Wireless website. Finally, I downloaded the pyocd --i nrf52840 package using CMD. Now I need a hex file, according to the instructions, but I don’t know what file it is or where I can get it. Can anyone help me?
I have a windows 11 pc.
Welcome to the forum @Limberth_Uc
There is no default firmware with LoRa US915.
For WisBlock you compile your own firmware and then flash it on the module, usually using USB, RAKDAP1 is more of use when the device is bricked.
Have a look into our RAK4631 Quickstart Guide
