Disabling NMEA Output on UART of HL6528

IoT Modules Legacy HL Series
1

Once I have activated the NMEA output on UART, I would like to disable it (after getting the GPS reading).
But, the UART interface doesn’t seem to react to any AT command after that.

Must we used the flow control to stop the NMEA output stream?

Thank you guys.

Okay, managed to figured it out.
Issuing the +++ sequence (without the next line CRLF characters) will stop the NMEA output. Information buried somewhere in the AT command documentation.
A very versatile and neat module.

Now need to try the GLONASS section!
