Does anyone have a working example of a datalogger using a cellular modem to stream to Azure?
FTPClient() is the easiest method, if you are not opposed to FTP.
Do you have a working example of a table being transferred in FTP over cellular?
There is a guide about FTP data streaming. I hope you find this useful:
