Periodic sending indication/notification through BLE

[Sang_Huynh]

Hi guys,

I'm a newbie to ESP32 BLE. I'm trying to periodic sending indication/notification using esp_ble_gatts_send_indicate function, it's worked fine when only sending one time but when I try periodic sending (using timer and task of FreeRTOS ), this function didn't work anymore, no error occur and only the indication haven't sent.

Have anyone met this issue and have any else solutions for periodic sending indication/notification. Thanks in advance.
