How to fix this error identifier and function is undefined/unused ?

[Bettapro]

Could you please share your platformio.ini?

[mr12obot]

please find below platformio.ini. Is there any missed?

I cannot test it, as I'm not in front of my pc, but I guess doing the following changes will solve.

In SolarTracerBlynk/SolarTracerBlynk.ino:

1. Replace line n. 179 configTime(0, 0, NTP_SERVER_CONNECT_TO); with configTime(0, 0, NTP_SERVER_CONNECT_TO, CURRENT_TIMEZONE);
2. Comment lines 180, 181.

Final result should be:

configTime(0, 0, NTP_SERVER_CONNECT_TO, CURRENT_TIMEZONE);
//setenv("TZ", CURRENT_TIMEZONE, 3);
//tzset();

EDIT: Just download latest version from v3.x.x, should solve it as well.

ok it works like a charm. then how about the 2nd log messages below ? it's look like something wrong with library ModbusMaster/src/util

'uint16_t crc16_update(uint16_t, uint8_t)' defined but not used [-Wunused-function]

[Bettapro]

It's a warning coming from modbusmaster lib., it tells that modbusmaster declared a function inside crc16.h, not used anywhere (that means I can remove it, gaining some extra bytes on flash memory).

Last warning is about a variable not used after its declaration. I guess that part could be coded a little bit better. I already planned to review the procedure on time sync so I will fix it there #21

As they are both warnings you can just ignore them and compile the project😉
