Hello Team

I would like to pair a Bluetooth audio headset to the EC200U-CN module to make and recieve voice calls. However I am unable to find a document or a application note which shows the same. I can only find one related to HFP-AG mode which is not what I want…

How can I pair a Bluetooth audio headset? Please share a document or how to guide for the below module

EC200UCNAC-N05-SNNSA

hi，
Because it is a temporary document, it requires an application before it can be sent. Do you need to communicate via Bluetooth? Use the following command to scan for Bluetooth devices.
AT+QBTGATSCAN=1

Ok. Can we use this command for scanning and pairing audio headset in HFP / HFP-AG mode?

How do we get access to the temporary document? Do we need to apply for it?

Thanks
