ESP32-WROOM-32 as client cannot received notification

[DaNiao88]

Hi All

I used ESP32-WROOM-32 as client to communicate with a BLE devices ( nordic), i can write and read char successfully.

But cannot get notification, before that i had write 0x0001 to notification char.

notification char, without descriptor.
+BLEGATTCCHAR:"char",0,5,2,0x6E400003B5A3F393E0A9E50E24DCCA9E,0x14

//
AT+BLEGATTCWR=0,5,2,,2
>

ERROR

//

ESP32-AT cannot work on notification without descriptor? how to fix it?

Thanks.

PS,

ESP32-WROOM-32 as client , ESP32-WROOM-32 as server , notification is working.
ESP32-WROOM-32 as client , Another BLE device as server , notification is working.
