mbed version of NUS (Nordic Uart Service) for nRF51822

[BLE_lp]

Hello, On Nordic Studio, there is a fairly well documented NUS (Nordic Uart Service) that provides a read and write characteristic, and it mimics uart. Data written to the nRF51822's uart RX pin is relayed to the corresponding BLE characteristic. Data written to the BLE RX characteristic is written out on the uart TX line.

Is there a similar implementation for the nRF51822 on mbed? The closest I could find is this:

developer.mbed.org/.../UART-access-over-BLE

And it's not clear to me that this was meant to mimic NUS. In fact, I don't see where it instantiates the serial port and baud rate.

Thanks, Eric

Hi Eric,

Yes, this implementation is supposted to be the equivalent of the ble_app_uart example in Nordic's SDK. You can see in the source code that the UARTService implements the same UUID's as is documented in the Nordic UART Service documentation.

The service itself does not require any actual UART terminals to be used, it only enables the transmission of strings over BLE in a UART-like manner. It can just as well be used for sending strings between two standalone boards. If you want serial output from the mbed example, you can add this using the Serial-library in mbed.

Best regards,

Jørgen
