ESP_gattc_demo Error:

[vishnunaik]

Dear Sir,
We are working on ESP_gattc_demo_code to connect a sensor-Bluetooth module (Server) with ESP32(Client).
I am facing two types of Errors:

i) We are able to connect to the server but not able to read the service and characteristic UUID
Errors Highlighted in the Yellow color box:

ii) When continuously pressing the reset button ESP32 able to read the service UUID provided by the server but not able to read the characteristic UUID at that instant. (This case is happening in random time)
Errors Highlighted in the Yellow color box:

When I went through your code which was updated in GitHub and the video tutorial: ESP32 #13:
Bluetooth Client reading from nRF51822 Server. I have seen one line which was there in video tutorial
is not exist in the updated code which is:
esp_ble_gattc_get_charcteristic (p_data->search res.conn_id, srvc_id, NULL): maybe because of this
in the second case, ESP32 not able read the characteristic UUID.
When I was adding this line to the updated gattc_code it is giving an error.

Sorry for writing this much big problem I hope you can understand my problem.
Thank you for your valuable time.
