If I call advertising_init after gap_params_init, can not see the device advertising ,can not see the device on phone, seems the ble is hang , but if stop debug, can run into main, means the program is not hang. Should I disconnect first, then call gap_params_init?

yes, correct. First gap_params_init() where you set the name with the sd_ble_gap_device_name_set() function, and then later advertising_init()

I use nRF connect for android, even if I refresh services, then disconnect, still show the old name , do I miss something? Do I need to call the advertising_init function after gap_params_init

Hi!

Likely the device name is cached by the phone. If you do a new service discovery, it should update.
