LC29hea: Is configuration from an Android serial terminal possible?

IoT Modules GNSS Module

Hi @Mohamad.firdaus, @bamarcant, and everyone else.
I’ve managed to build a working rover with the LC29hea, one HC05 module, a battery, and other components.
Except for the missing GST messages, it works very well.
Now for my question.
Is it possible to configure the LC29hea via Bluetooth from an Android serial terminal? I connect, I see the NMEA messages running, but it doesn’t respond to the configuration messages.
I look forward to your ideas, as always.

Regards, Angel

Yea , use kai-morich.de app; but must pair the Classic SPP and send the stop command before…
$PAIR003*39 or $PQTMGNSSSTOP*09

if there are too many nmea messages , the link can be busy and the bt_module hangs in bidirectional…

Thanks @bamarcant
It’s the app I was using, but I hadn’t thought about stopping the GNSS engine.

Thank you very much.
