"SPP-C Bluetooth" not work

I’m trying to use a Zero SAMD connected with Bluetooth SPP-C, but remains in connecting and not connecting.

It’s not compatible ?
With the terminal texts correctly passed.

However, the terminal asks me which module to use.
The Blynk app does not ask me anything.


I don’t know if SPP-C is different from SPP
And if this chip is different from HC-05
Both sent character using serial port.

  • Bluetooth 2.0 Serial Port Profile (SPP)
    • HC-05, HC-06, …
