BLE APP UART

[karelv]

Hello,

This example I got it working with nrf toolbox app, but I was wondering if this should work also with a win7 PC.

I got this window:

But it never asked for a pairing code.

Best regards,
Karel.

Actually I am looking for a python way to interact with this BLE-UART.

In fact the nRF Toolbox / UART only can sent something to the nRF52, it never replies.
I added one line of code as I don't know how the toolbox is sending a \r or \n, such that it ends with a 0, it also echo the received string. So sending "test0" should trigger the nRF52 to send "test0" back to the toolbox-app, but it doesn't.

Sorry, I was too quick; the example is a little more complex. It deals with 2 UARTs. Now I can receive info from nRF52 to toolbox app.

The UART/Serial Port Emulation over BLE example will not echo the sent data back to the Toolbox/nrf Connect/ NRf UART application, but it will send the data out on the UART of the nRF52. So if you send data from one of the smartphone apps then the sent message will be outputted on the UART of the nRF52 and vice versa, any data sent to the nRF52 over UART will be sent over BLE to the smartphone app. 

Best regards

Hello Bjorn,

Yes, understood!
Any idea if I can interface this BLE-UART from this demo from within a python program?

Thanks,
Karel.
