Hi,
I'm using nrf connect SDK 2.3.0 with custom board, Now, I would like to be able to upgrade the firmware of the board in future, The DFU procedure should be performed over UART.
Hardware setup :- UART pins(rx) of a board (with nrf52833 soc) is connected to laptop via UART TTL converter(COM7 port)
I was able locate this document online, make the necessary modifications, and installed the mcumgr module using the go module.
However, commands are not working, if i give this command "mcumgr --conntype serial --connstring "COM7,baud=115200" echo hello" it's returning with "NMP TIMEOUT"
And this is my prj.confg file
