Can't read from UART EVK_NINA_B1

[schef]

Hi guys. I have a EVK_NINA_B1 board which is based on nrf52832 and SDK12. I am trying to run the ble_peripheral/ble_app_uart/ from examples. I can send message through "nrf uart" android app and have recived messages on my tty terminal window on my PC. But when i try to send a message back it doesn't work.

I have also tested peripheral/uart and i get no output on recive or send on my tty app. What am i doing wrong? Is there a way to debug this situation?

I have used: baudrate 115200 databits 8 stopbits 1 flowcontrol hard parity none

Thanks.

Hi schef,

We need to make sure UART works properly first.

Could you uncheck flow control ?

Which app did you use to test with UART ?

If you have a logic analyzer you can hook it in the UART pins and check if there is some signal .
