i have found the problem. someone gave me a wrong base uuid, so i can't use 0. i have to generate a base uuid myself. thanks for your help.

I did a quick test with ble_app_uart. It works fine.

Here is my project, unzip it to examples\ble_peripheral

I used SDK 9.0.0 with SoftDevice 110 8.0.0.

i use sd_ble_uuid_vs_add() to add vendor specific uuid firstly, and then initialize the uuid, setting the uuid.uuid to 0x0. finaly i use sd_ble_gatts_service_add() to add service. all of above are in the init function which will be callled in services_init() in main.c file.

How are you setting it to 0x0? Are you using vendor specific UUIDs? Did it advertise before you made the change?
