Quectel M66 HTTP POST empty data is getting stored in the server instead of string

[marzzzz]

Hi There!

I am using a Quectel M66 GSM/GPRS module to post data to an AWS server using AT Commands with the help of the TeraTerm serial monitor. The database stores data in plain text format. The board I am using is https://evelta.com/m66-gsm-gprs-breakout-audio-jack/#productDescription. I have tested this board for SMS to send SMS and HTTP GET to read data from a server, and these are working properly. But when I do HTTP POST, it shows as data sent successfully in the HTTPREAD, but when I check the server using Postman, an empty row gets added instead of the data I type. Since an empty row gets added, I am assuming there is no error in HTTP connectivity, but somehow data becomes empty. Is it because the server is not able to read the data I type? I have tested the same API using a SIM7600EI module and with that, I am able to POST data successfully. I have attached the screenshot of the AT commands I have used to POST the data using Quectel M66. Please help me fix this issue.

Thanks in advance!

Is the modem otherwise working OK? Have you checked it with basic AT commands for sending SMS etc.?

Yes, I have tested with SMS and HTTP GET AT commands. These are working fine. HTTP POST is not.
