Dongle Firmware for Desktop App Serial Over BLE

[WestCoastDaz]

Dear Nordic Team,

We have a customer that would like us to extend an C# desktop application to use serial over BLE. What is the best dongle firmware and Windows driver combination to accomplish this?

Thanks, Darren

Hi Darren

In the nRF5 SDK v12.x.x you will find ble_app_uart examples that can be used with the nRF51822.
Unfortunately we only have board support in the examples for the PCA10028 (51DK), but if you change the board definitions it should not be a lot of work to make it run on the PCA10031 (51 Dongle).

Then you can use two nRF51 dongles to act as a serial link between two PC's, and access the serial ports from C#.

Best regards

Torbjorn,

Thanks for the great answer. In your proposed solution how do the two devices find each other and establish a connection?

Hi Darren

The devices will use the advertising name to connect. As long as they are configured with the same (preferably unique) name the central will automatically connect to the right peripheral.

Best regards
