Works perfect! THANKS!!! Now I can watch myself losing money again!

I have downloaded again the above code for a WLAN connection. It did not work! The following error message appeared: Token info: type = id token (GITKit token), status = on request Token info: type = id token (GITKit token), status = error Token error: code: -105, message: Client is not yet initialized After that i downgraded the library "Firebase Arduino Client Library for ESP8266 and ESP32" to 2.3.7 and after that i reinstalled 4.2.7 and it worked again. Why do i need to reinstall the lib to get it working?

I use UIFlow i get weard readings like -482827.3 when connect to pa.hub but connected direct to core 2 ewerything is ok

Nope, you have deep fried it, the poor thing was only rated at 3.3v

Hello @BennoB I can confirm that the UiFlow example doesn't work for me either. The block to connect to MQTT seems to be broken or not properly adapted for the SIM7020. @m5stack : please fix. Thank you. Thanks Felix

DuPont or 2.54 is the standees size for headers and connectors. For the ‘-Bus internal connector you need an I/o breakout board or base as the connector is shallow to save space.

Hello @aezero I am glad to hear you found a solution. And thank you for sharing. BTW: for me a rate limit of 10 reduces the download time (from about 70 s to 55 s). Thanks Felix
