Hi, thank you for your nice work.
I found a little Issue.
The password for the AP mode must at least use a minimum of 8 char.
Otherwise the method call WiFi.softAP(AP_ssid, AP_password); will fail and it give a generic SSID (e.g. ESP_32_83A4H) without password.

Hi Andreas,
you are writing at ttlappalainen/NMEA2000#97 (comment) that

BTW: The AZDelivery ESP32 NODE MCU is using:

GPIO2 -> CAN TX
GPIO4 -> CAN RX

But I could not find those pin definitions in your code?

Thanks,
Ronnie

Hi, I thank you so much for this code, it saved me a lot of time.
I found a slight issue: GetTemperature is delaying the main loop, I found this when I added a small oled display with a counter increasing every loop. I could see the counting freezing for about 0.5 second almost every 1 second.

I fixed it by making xTaskCreatePinnedToCore priority 0, removing the "delay" from GetTemperature, and adding vTaskDelay(100) after sensors.requestTemperatures() and another vTaskDelay(100) at the end. Now the counter does not freeze and GetTemperature still working correctly.

I've built the gateway, and the TCP connection is working fine. However, UDP does not seem to be working, even though UDP_Forwarding is set to 1. Does anyone have any clues as to why that might be?

HI, i tried to compile this code on Atom PlatformIO. Using different espressif32 platform versions (1.7.0, 1.8.0 and the last 1.12.4) i have the same error at the end of compiling;

Is there some kind a problem in one library?
Thanks

Hi
I have problems when trying to compile you NMEA-Gateway.

Wifi-Serial-AP-AIS-CAN.ino: 413:11: error: StaticJsonBuffer is a class from ArduinoJson 5. Please see arduinojson.org\upgrade to learn how to upgrade your program to ArduinoJson version 6
StaticJsonBuffer<800> jsonBuffer

Any solution/recommendation?

Best Regards Uwe
