Custom UUID service on nRF51

[Nguyen Don]

Hello, 

Currently I am connecting between nrf51822 and Rn4871 BLE of Microchip

The issue is that Rn4871 is advertising a service called transparent UART UUID : 49535343-FE7D-4AE5-8FA9-9FAFD205E455 with the characters below:

TX : 49535343-1E4D-4BD9-BA61-23C647249616

RX : 49535343-8841-43F4-A8D4-ECBE34729BB3

i worked on modifying the NUS example

#define NUS_BASE_UUID {{0x9E, 0xCA, 0xDC, 0x24, 0x0E, 0xE5, 0xA9, 0xE0, 0x93, 0xF3, 0xA3, 0xB5, 0x00, 0x00, 0x40, 0x6E}}        //< Used vendor specific UUID. //
#define BLE_UUID_NUS_SERVICE 0x0001                                  //< The UUID of the Nordic UART Service.
#define BLE_UUID_NUS_TX_CHARACTERISTIC 0x0002            //< The UUID of the TX Characteristic.
#define BLE_UUID_NUS_RX_CHARACTERISTIC 0x0003            //< The UUID of the RX Characteristic.

which basically build :

service : 6E400001- B5A3-F393-E0A9-E50E24DCCA9E

TX char : 6E400002- B5A3-F393-E0A9-E50E24DCCA9E

TX char : 6E400003- B5A3-F393-E0A9-E50E24DCCA9E

The NUS allowed me to only modify "BLE_UUID_NUS_TX_CHARACTERISTIC " and "BLE_UUID_NUS_TX_CHARACTERISTIC " but the characteristics of the Transparent uart service of RN4871 have some differences even in other bytes of the service.

How would i modify my service and characteristics of the Nrf51822 to be identical to the Rn4871 characteristics so i could send/receive data between these modules?

Could someone help please?

Hi

Please check out our custom BLE service tutorial here explaining how you can add custom services/characteristics to an example project. I'm not familiar with the Rn4871 I'm afraid, and I think you'll have to ask Microchip for assistance on that end.

Best regards,

Simon

Hi Simonr,

thanks for the reply, I read example of your, but services only change byte 13th,14th, I want change all

Could someone help please?
