Yes, of course! My UUID was wrong..

Thank you :)

Hi,

If you need multilink central support, then the multilink central example is a good starting point.

Regarding the error "Service UUID 0x1400 Not found", please make sure that you also use the same UUID BASE on both central and peripheral. I.e. the CUSTOM_SERVICE_UUID_BASE that is used on the peripheral, is also the same as the UUID base used on the central side(originally named LBS_UUID_BASE on the multilink central example).

Hey Sigurd,

The service that the peripheral device have is 0x1400 and the characteristic is 0x1401.

I followed this tutorial to make a custom service, https://github.com/bjornspockeli/custom_ble_service_example. So the peripheral device is made from the ble_app_template and modified as in the tutorial.

Yes, that was the thought. Or is I maybe better to use something else when i want a custom service?

I tried that fist before I remembered that the service and character on the peripheral side was different. I have not tried it with the ble_app_uart on the peripheral side.

Hi,

What services and characteristics does the peripheral device have?
Is it ble_app_uart peripheral you are trying to connect to? If yes, did you make any changes to that peripheral example, e.g. the UUID values?
Your goal is to implement multilink central for NUS?

Does it work if you try the default UUID’s for NUS ?

#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_RX_CHARACTERISTIC  0x0002                      /**< The UUID of the RX Characteristic. */
#define BLE_UUID_NUS_TX_CHARACTERISTIC  0x0003                      /**< The UUID of the TX Characteristic. */
