Http post json to thingspeak from Arduino using GPRS via GSM module

19 views (last 30 days)
I need to send bulk data from my arduino device via Quectel M66 GSM module. I succedded sending data using the GET method but for bulk data I am trying to json data using POST method. But after establishing the connection when I post the data I get an error. I am following examples on this page
The problem is the GSM module sends module specific error code and does not speficy the 40x or 50x error. So I am not able to pinpoint the error. I am attaching the commands sent by my device. Please guide.

What do you mean by "use a client class embedded library like tinyGSM". And does that mean you aren't limited by 5 entries if you use this other library?

My guess on the five entries limit is the size of the data buffer used in your communication library. (either the arduino or the GSM.)
