I've used some weird iterating function to print out AT+HELP commands for this controller and AT+TYPE is not listed there as a command. That means I cant set pairing method? What kind of BLE device has pairing disabled and there is not option to set up at least password?

Here are my commands

HM-10 BLE controller is not responding to some AT commands

I have HM-10 BLE controller and it is not responding to some AT commands which I need to use.

AT commands which don't work:

  • AT+TYPE2 returns +TYPE=0
  • AT+VERR? not responding
  • AT+VERS? not responding
  • AT+RESTART not responding
  • AT not responding but AT+responds with OK
  • AT+VERSION responding with MLT-BT05-V4.1

The most important command for me is AT+TYPE2 because even if I set pin with command AT+PIN112233, in my Android App, AlertDialog with password field is not activated during connection with bleGatt = bleDevice.connectGatt(this, true, bleGattCallback) function.

I even tried to call createBond() function on this device, but it is not returning anything. I need to activate pairing with password with AT+TYPE2 but its always returning 0 which is default connection without password and pairing method.

I'm not sure if I have some bugged HM-10 controller but I cant even reset it to default settings. It is working fine with transfering data by characteristics but other stuff is not working.
