Changing Bluetooth protocols

[Xavali7]

Hello, I bought the Data Logger, with the dual Bluetooth chip, so that I could use both protocols (Classic and BLE).

However, I can't find how to change the protocol from one to another. It's working with BLE, but I need it to use Classic Bluetooth. How can I change this setting? I suppose it's a configuration or the BT chip, not the Arduino board...

Stanley, please, help!

Both are available at the same time. No configuration needed.

Then, how can I pair the device with my pone if I want to use a Bluetooth Classic terminal? None of the typical passcodes seems to work (0000 or 1234, all 4-same-number combinations, all 4-ascending-numbers combinations...). I even tried 000000, as some documentation I found on the chip (don't remember where) suggested...

I believed that I couldn't pair them because some option was setting the protocol to BLE. What's the solution, then?

Make sure BLE is not connected if you want to pair BT SPP. Pairing password should be 1234.

I already tried pairing before using BLE, but, as I said, all passwords (1234 is one of them) are rejected and the pairing doesn't work...

BLE does need pairing. It is connected programatically. BT SPP needs pairing.
