Re: GPS parsing using UART

After playing with Arduino, I flashed again the ESP32 board with the latest micropython, and re-install uasyncio: it works now. The example code provided by Peter works perfectly, the one connecting Rx and Tx together. However, when I adapted it for reading the GPS stream, it fails just like the cod...

Re: GPS on ESP32 running micropython

I would be interested to know if you had any success using a GPS module with an ESP32. I have been trying for quite some time to read NMEA lines from a NEO-7M module, without success: most lines get corrupted. Although, I sometimes get lucky and after reboot everything works, but since this happens ...

Re: GPS parsing using UART

After efforts spread over months, I could not make uasyncio work on the ESP32, so I have switched to a Raspberry pi Zero-W running full-fledge linux and moved forward on my project (and confirmed my GPS unit is not defective). Today, I gave a try to Arduino to convince myself that my ESP32 board is ...

Re: GPS parsing using UART

Hi Peter, Finally got back to this... to find out the current esp32 version of micropython (MicroPython v1.9.2-272-g0d183d7f) does not have asyncio. I tried to figure out how to install it but I failed. The only thing I could find is https://forum.micropython.org/viewtopic.php?f=18&t=3691&hilit=uasy...

Re: GPS parsing using UART

Thanks Peter for the suggestions, but unfortunately it does not help... The result is basically the same: some lines are well formed, but most of them are missing characters, not only at the end of the line, and sometimes most of the line is missing. I do not have a pyboard, unfortunately. In the me...

GPS parsing using UART

I am trying to read the NMEA serial stream of a NEO-7M GPS module on an ESP32 dev board. I monitor the output lines and check their validity (NMEA lines come with a checksum). Most of the time, reading the flow of serial stream fails: only a few lines come with valid checksum, because there are miss...
