So, I tried to install my ESP32 today and it didn’t work. Raymarine told me NO DATA.
Feel free to chip in if you have any ideas of why it may not be working.
I tried the following:
- As described above, 3v3 to nmea+ and tx to nmea-
- same thing, + a 4k7 pull down resister between tx and gnd to avoid pin floating
- other code: HardwareSerial.sender(1). In void-setup I used: Sender.begin(4800, Serial8N1, 27, 14) with pin 27 as tx to nmea-. And then I used Sender.write(my nmea).
None of it worked. I assume NMEA is 8N1 at 4800 br.
Any bright ideas?
Br, Peter
I’ll check my serial outputs tomorrow and see if I can troubleshoot the problem..
