Secure UART Pairing for Central and Peripheral Examples

[Aashay]

Hey guys, I am using 2 nRF52832 boards with a PCA10040. I program my boards with the BLE UART central and peripheral examples. I was wondering if it is possible to, and if so how to, make the pairing process secure between the 2 boards. As of now, after I program the examples, the boards just connect automatically and both LED1's turn on. I was wondering if we could make the pairing process start after pressing BUTTON1 on the boards. And then when they successfully pair, the LED1's turn on. Any help is great. If you know how to do it or have done something similar, please share in detail or even share your code if you're willing. Thanks!!

Hi, 

there are two examples (as your reference)

Simon Hey, I have read many threads in which you were very involved in topics related directly related to this. It would be great to get your input or help on this. Thanks :)

Also I was thinking how it would be possible to incorporate BUTTON2 and have it act as a RESET/ERASE Pairing Link that would terminate the already established link between 2 boards.

Simon, I have looked at some of your examples you've posted on other threads but I don't understand how I would change the syntax to make the pairing dependent on buttons rather than a password.

You will need to add the peer manager to the NUS examples in order to support pairing/bonding. You should take a look at another example on how it is done, for example ble_app_hrs.
