How to Connect A HC-42 Bluetooth 5.0BLE Module

[harunsengul]

Hi,

I have a device that has HC-42 Bluetooth 5.0BLE module and I want to connect it via esp32-wroom-32.

I found the UUID of the device but there is no characteristic UUID.

I've used BLE_client example to connect my HC-42 module but it did not work.

Thank you in advance in your help.
