Hi sir. It's possible to use this library with ESP32 togheter WIZNET W5500?

Thanks!!

Best Regards

This library is only read in 1 port of 1 ip device ?? i have a problem that need to read three devices on 3 ports on 1 IP ?? i found your default is 502 and i want to read both 5023 5021 5022 502 port so what can i do to make it sucessful ?

What are the prospects of integrating your library with ESP8266WiFi (part of the ESP8266 core)?

Seems like your library is the only with tcp modbus master capabilities... Thanks.

My new nodeMCU board (purchased March 2018), having no additional wiring other than the USB to a PC, will not respond with any wifi networks upon running a WiFi.scanNetworks call. The board is surrounded by many networks as per the results of my phone sitting next to it. Other sketches for serial communications work, as do sketches on the GPIO pins with sensors, but the WiFi does not work to minimally see networks.

I've tried flashing it, using capacitors for the power supply, grounding some pins, etc. This nodeMCU from HiLetGo with AI-THINKER ESP8266 just won't "see" any networks. Attempting to log into a specific network with WiFi.begin obviously doesn't work either because it doesn't see the network.

Can someone tell me if there is an even more basic test than WiFi.scanNetworks to run to determine if the WiFi portion of this chip is working?

Hello,

I am having the same issue as issue #5. I see it was closed but the original poster replied after it was closed with same results I am getting.

Arduino IDE 1.8.8 - Windows 10 - W5100 Ethernet Shield

I have read the read me file that shows an example. I was not able to find a "user guide" as suggested in the #5 solution post? Based on that example this is what I interpret as the correct #define method?

#define WIZNET_W5100 = 1
#define ENC28J60 = 0
#define ESP8266 = 0

Oddly the sample program shows a different method and fails with the same error. Sample programs shows #define WIZNET_W5100 1. I also tried this format with removing the "=" from each line same error.

Is there another document I am missing?

Any help would be greatly appreciated.

Thanks,
Mike

Does this library support retrieving float values from a holding register?
