Topic: ESP8266 with MAX32

Hi, I've successfully tested a Bluetooth module and a Ethernet shield W5100 on a UNO. But, when I tried to use ESP8266 using UNO, MAX32, etc it never worked. The router recognises the module and gives it a IP and I can connect to it using the serial conection. It responds to the GMR and RST commands. Now I'm focusing on MAX32 because it is safer, I have 3.3V logic. I used HW Serial conection 1 that uses pins 18(TX1) and 19(RX1). I've noticed that the pins are swapped in the RemoteXY editor, i.e., it appears pins 18(RX1) and 19(TX1). But I've tried with pins 0 and 1 which are correct in the editor and it still get ECONNREFUSED (Conection refused)
Thank you in advance,
Paulo

Re: ESP8266 with MAX32

Yes. Hardware Serial pins for MAX32 was error. We fixed it.
Try to use debug mode. Add in you sketch next code before RemoteXY #include <RemoteXY.h>:

#define REMOTEXY__DEBUGLOGS Serial

You can see the debug info of connection on Serial port on 115200. Maybe it helps you.

Re: ESP8266 with MAX32

Thank you for your kind help. I'll check it as soon as I can.
I also tried your example for reading temperature and humidity through the W5100, and it works fine for some hours, but then, next day I try to conect and it can't. Then I power off and on the board and it works again. Maybe some little bug crawling around big_smile

Ok, your help was great. At least now I know that the module fails to connect to the router. I don't know what possibly can be the problem!!!

Re: ESP8266 with MAX32

Ok, now I made a RESET to the router and now it runs fine. I already conected from outside my local net. My router is a NUMERICABLE and its instructions are in French and I don't understand much french but I assigned a transfer from a port to a IP. From what I understand I'll have to use a different port for every board that I want to control from outside. Is this correct?
Thank you, you have a very nice app.
