Hi, thank you for the assistance and availability of the technicians (@george). I’m still experimenting with the bluetooth connection (classic) esp32 wroom module connected via rx and px pins.
Through the serial monitor of the Android Serial Bluetooth app I see that the data is transmitted but the nmea strings are “infested” with special characters and do not have the correct format.
I think that’s why the gnss master app tells me it’s not receiving nmea! I attach a screenshot and the sketch set to esp32.
I tried several changes to the sketch but I didn’t solve it. maybe the problem is something else.
Does anyone already have experience with this and can help me?
Have a good day everyone

Hi @falajons
- Some garbled information exists in the received NMEA information. Is LC29HEA opening RTCM data or Binary data?
- If outputted through UART, can it be outputted normally?
Thanks George but I don’t understand exactly what you’re asking or what I should do.
- question: how do I determine whether it is opening RTCM data or binary data??;
- I really don’t understand the second question (I apologize).
At the moment I have suspended experiments with bluetooth modules or esp32 modules because I have the sensation of having problems with the uart port as I described in my last message.
thanks again
Hi @falajons
- In the “Binary data” window of the QGNSS tool, if the output is RTCM information, then RTCM is turned on. If the “Binary data” output is not RTCM, then it is Binary data.
- If the output directly through the serial port is normal, then it means that there is a problem with your main control processing.
