NRF52840 radio receiver problem

[diyguy]

I try to communicate with NRF52832 with NRF51822 for the example radio receiver and works well with SDK5 12 3

when I try to communicate with E73 (NRF52840) board(E73(2G4M08S1C) ,  with SDK 5 15 2. I think the TX RX is 0.06 or 0.08. is that correct?

#define RX_PIN_NUMBER 8
#define TX_PIN_NUMBER 6

I try to avoid and use the outter pin, and remap to 0.21, 0.22

 , I tried to change the pca10056.h for the line

 #define RX_PIN_NUMBER NRF_GPIO_PIN_MAP(0,21)
 #define TX_PIN_NUMBER NRF_GPIO_PIN_MAP(0,22)

But I still cannot receive when I press the buttons on NRF52832 boards. Do you have any hints.

What debugging have you done?

Your title says "radio receiver problem" - but your post talks only about wired UART connections.

You could check your hardware connections with a simple app to toggle GPIO pins ...
