I actually got this to work by changing the generated handle used in the generated set function. The original generated ble_YY_XX_characteristic_user_description_set function calls the code return sd_ble_gatts_value_set(p_YY->conn_handle, p_YY->XX_characteristic_user_description_handles.value_handle, &gatts_value); but I never found where this handle was initialized by the generated code. I changed the code to return sd_ble_gatts_value_set(p_YY->conn_handle, p_YY->XX_handles.user_desc_handle, &gatts_value); because this is the handle that is used in the generated _init() function when setting up all the descriptors. I believe this is a bug in the BDS plugin when generating code for this function.

Hi Sigurd, The parameters for the CUD is request_XX_characteristic_user_description.read_access = SEC_OPEN; request_XX_characteristic_user_description.write_access = SEC_NO_ACCESS;

However I am NOT trying to write from the Central(Phone). I'm trying to update the CUD from the Peripheral (ble device).

Hi,

How does your User Description Security requirement looks like? Have you enabled write_access ?
