2 nRF devices connected via UART profile

[ypearson]

Is it possible to have two nRF52 devices connected in such a way to send UART data in a bi-directional way.

Would device 1 be a BLE central and the other BLE peripheral? How about if both are peripheral & central? Ideally the firmware on both devices would be identical at least for the final solution.

thanks.,

Hi

In the SDK you will find examples for both peripheral and central that implement the Nordic UART service, and these are designed to go together. They allow bi-directional UART communication between the two kits.

It is theoretically possible to combine these into the same project, but then you need to find some way to determine who should go into which role. In any BLE connection you need one device to be the peripheral (slave), and one to be the central (master).

awneil already linked to the documentation for these two examples in his reply.
