Basic UART over BLE?

@Aryan, the example is not working for me using PCA10028, SDK v8.0.0, S110 v8.0.0. The APP shows RX logs but NOT TX logs no matter the size of the message I send or hardcode, with or without a newline character. If I skip over uart and fifo (directly echo back what comes in on nus_data_handler out to ble_nus_string_send) then I can get TX logs. app_uart and app_fifo seem to break the example.

If the memory settings are incorrect, you are probably using the incompatible SDK and SoftDevice.

It sounds like ble_app_uart is a very good starting point for your application

in ble_uart you send a string from the terminal on the PC over UART to the nRF51, then the string is relayed over BLE to peer APP with ble_nus_string_send().

You send a string from the APP over BLE to the nRF51, then the string is relay to the terminal on the PC over UART with nus_data_handler().

To send data to your phone from nRFchip: just call ble_nus_string_send

When you receive data over BLE from your phone nus_data_handler will be called, so you have handle your incoming character

@Aryan, I do NOT care about the UART hardware peripheral. I only care about sending/receiving debug data over BLE to/from an iOS device. 'Emulated' UART might be a better description I could have put down.

Hi la-ble,

I am not sure if I understand what you mean by abstract put_char and on_char_received. Are you saying that you do not need to forward BLE traffic to/from UART? Or are you asking if you can use NUS service and also abstract put_char and on_char_received functions in addition to NUS?

I will help you and edit my answer after I understand what you are really looking for
