I've got a custom board that puts UART_TX on P0.14 and UART_RX on P0.15, with no RTS or CTS signals. I've got a USB to UART cable that I've plugged in, and I know at the very least the TX line is working because I've seen data go from my custom board to the PC when using my application code.
However, I need to evaluate the performance of the radio circuitry and I cannot find any documentation about how to do this with a custom board. Everything uses the development kits, which is no good.
All I care about for now is generating carriers and modulated signals. I don't need to test inter-device connections yet.
I'm using the nrf connect SDK v2.6.0.
I've tried building the radio_test example, which I can get working on the nRF52 DK I've got. I can get it to build using my custom board overlay/Kconfig/defconfig files, but it doesn't seem to send or receive anything over the UART connection once it's been flashed to my custom board.
I've tried creating a new application based on the direct_test_mode application, but doesn't seem to be compatible with the nRF52832 dev kit, never mind a custom board.
I think the radio_test example is probably my best bet, but is there a simple guide as to how to change the UART pins? Does it need the RTS and CTS signals?
