Communication between nRF52832DK and nRF9160DK

[Siang]

Hello, I have a nRF52832 DK and a nRF9160 DK and I would like to establish a Bluetooth connection between them and also send data to each other. How can I do that?

One of them will have to be a Central, and one will have to be a Peripheral.

Check the SDKs for examples.

Do you mean ble_app_uart_c and ble_app_uart? I have flashed them into the boards and not sure if they're working.

I have tried previously with ble_app_blinky_c on 52832 DK and ble_app_blinky on 9160 DK. I can see that the LED 2 on the 52832 DK turned on when it is connecting to the 9160 DK but LED 3 never turned on. Does it mean that the connection wasn't complete?

The key thing with this kind of stuff is not to try to do both ends at once - otherwise, when you get problems, you don't know which end has the problem. Or it could be both.

This is why people like Nordic provide things like the nRF Connect app - it gives you a known-good platform to check against.

So check each end with the nRF Connect app first - to verify that each end is working on its own.

Sorry I'm not sure how to check that using nRF Connect app. Could you please explain more?

I have tested with the nRF Connect app. Basically, the UART works on the nRF52832 DK but not on the nRF9160 DK. Can I know which code should I flash on them in order to connect them together via Bluetooth?
