error 7 NRF_ERROR_INVALID_PARAM when i use sd_ble_gatts_service_add

[Samy-DPE]

Hello,

First, I follow this tutorial --> https://devzone.nordicsemi.com/tutorials/b/bluetooth-low-energy/posts/ble-services-a-beginners-tutorial. It's working well on the dev board PCA10040 with the softdevice s132 and the sdk v15.0.0.

Now I trying to launch the same thing on a custom board with the nrf52810 with the softdevice s112 and also sdk v15.0.0. But when i try to add my custom service with sd_ble_gatts_service(), I have a error 7 (NRF_ERROR_INVALID_PARAM). I had followed the tutorial step by step until STEP 4.

On a ble analyser, I found my device but of course i can't see my custom service.

My IDE is keil 5 on Windows.

do you have a solution for me?

If you haven't added the vendor specific UUID to the BLE stack table, you will get this error. Are you sure you have correctly added the base uuid using sd_ble_uuid_vs_add()? Could you upload some code?

Best regards,

Simon

Yes, I used sd_ble_uuid_vs_add() before sd_ble_gatts_service().

OK, I have more information. When I used sd_ble_uuid_vs_add my service_uuid.type stay at 0x00 (BLE_UUID_TYPE_UNKNOWN) . Normally this value need to be at 0x02 (BLE_UUID_TYPE_VENDOR_BEGIN). I don't know if this observation can help you to find my problem.

[Samy-DPE]

The solution is in the sdk_config.

To solved it, I put 1 instead of 0 at the define NRF_SDH_BLE_VS_UUID_COUNT.

Thank you for your help
