UART communication not working properly

[Yogeshwaran]

Hi all i am trying make a communication between esp32 and nrf52840 using UART. Initializing the uart driver was proper and pins also correct. when nrf start transmits then esp32 will not receive but strange things happening here is if i remove the uart pins from esp32 at that time i am getting some bunch of data. I had checked the wires connection and everything was tight. Same issue happening with arduino also.

I am totally lost because the data was coming but at the removal of connection. NRF pins are rx-25, tx-26 which i modified in ble_app_uart_c example.

Hi,

It would really make it easier for us to to help you if you provided us with your code and a trace of the UART pins from a logical analyzer or similar.

Yeah the issue got solved. Mistake is i am reading for string and i am sending as a byte from transmitter. So string terminates with null character. Then i changed my esp32 code such that it will look for bytes. Thanks for your concern.
