Serial communication with nRF52832

[ML.PT]

Hi!

I just bought a BLE Nano board featuring nRF52832 chip. I am using it with Arduino IDE, controlling some servos and motors onboard my autonomous device. I would like to communicate with it by bluetooth serial channel. Though all samples that I found kinda won't do what I want. The only thing that I got working "properly" was a fake hear rate monitor working with nRF Toolbox.

Is it there a sample code which would allow me to pair nRF52832 to android or PC as a UART device so I could use serial stream to send commands and receive a status data from my device?

Thanks.

Not really because there is no Bluetooth Low Energy profile or service definition by BT SIG (or similar standardization body) for virtual COM port (or other form of "serial" communication). If you want to object that your PC can do that over Bluetooth with any phone or similar device then it's Bluetooth classic (BR/EDR) not Low Energy. There is popular Nordic BLE UART Service implementation in nRF5 SDK which simulates basic serial full-duplex link over BLE (no flow control, you need to take care about these things on higher layer) but for that you need specific app on both sides. Still there are all iOS/Android/Win/Linux/Mac implementation available by Nordic in some form so it might be what you want...

Do you mean pc <--uart--> BLE nano? The sample code from the ..\nRF5_SDK_12.2.0_f012efa\examples\peripheral\uart folder should be a good starting point for your experiment.

Or do you mean pc with BLE support <--BLE--> BLE nano? Then you mean want to look at the sample code in the ..\nRF5_SDK_12.2.0_f012efa\examples\ble_peripheral\ble_app_uart folder.

(still NUS examples in nRF5 SDK are only for embedded part, he needs also something to emulate the counter part on rich OS device...)

So if I want to have a simple stream-like communication channel, there is no standard solution? I need to implement something like BLE_Serial example and to have a custom driver on an other end? ***. Seems that I made a wrong turn choosing BLE Nano...

So if I want to use BLE_Serial (nordic uart service) example as a base, I would need a driver on a PC side?
