How to pair exact two nrf52832 central and peripheral.

[n.izdebski]

Hello,

I have two nrf52832 own boards. First is BLE_central receiver, second is BLE_peripheral transmiter. 

SDK 15, SD-140.

I need to pair specyfic transmiter with specyfic receiver for few pairs of them.

I cant find any example or tutorial how to do that.

Can sombody guide me a little bit where to look?

Hi,

Have a look at UART central example and UART peripheral example. Is it what you are looking for?

The central application will scan and connect to peripheral devices that advertises with a specific UUID in its advertisement report, that is NUS UUID in this case.

#define BLE_UUID_NUS_SERVICE 0x0001 /**< The UUID of the Nordic UART Service. */
#define BLE_UUID_NUS_RX_CHARACTERISTIC 0x0002 /**< The UUID of the RX Characteristic. */
#define BLE_UUID_NUS_TX_CHARACTERISTIC 0x0003/**< The UUID of the TX Characteristic. */

I see that  i con match BLE_UUID_NUS_SERVICE adress on peripheral and central. But what is BLE_UUID_NUS_RX_CHARACTERISTIC.?
