ERROR CODE 12291

[Swapnil]

Hello,

I am trying to update temperature value through BLE characteristics example but while temperature update in following function I am getting error code 12291.

err_code = sd_ble_gatts_hvx(p_our_service->conn_handle, &hvx_params);

What is the meaning of this error code?

This is the error BLE_ERROR_INVALID_ATTR_HANDLE . This means that a invalid attribute handle is supplied. Only attributes added directly by the application are available to notify and indicate.

Please check if you have missed a step in the tutorial.

Thank you for your answer and I am checking my code, but i found that i followed every step precisely. In function our_char_add(), i added the recommended code properly. If you know what part can cause this error can you please suggest.
