ESP32 Not able to pair with HC-05 Bluetooth Module

Postby Yuvaraj1867 » Tue Dec 21, 2021 5:52 am

Dear Team,

We are trying to connect ESP32 (master) and HC-05 (slave) by using classic Bluetooth protocol. But not able to pair to HC – 05.

ESP32 loaded with AT firmware v2.2.0. ESP32 as a master and mobile phone as a slave we are able to connect.

Tried with Arduino example “SerialToSerialBTM.ino” also we are not able to pair with HC-05.

Do you have any suggestions for this? Because it’s very urgent.

You can refer to https://docs.espressif.com/projects/esp ... ent-boards. The example uses two ESP32 boards to establish SPP connection.

Hi
Was this ever resolved? We are trying to achieve the same thing but with a Parani BT dongle instead of HC-05 module and seeing the exact same problem. ESP32 BT SPP Slave works fine but fails to connect when used as BT SPP Master.
