Issue with receive data over TCP connection with MC60

giampietro.pomponio · February 5, 2020, 11:47am

I’m using MC60 (No-Trasparent Mode + Multiple connection).
I must exchange info with a server but after the first data received by the server, I don’t receive the notification +QIRDI.
I indicate the steps followed:

Initialize GSM and GPRS network
Activate the PDP contex with AT+QIREGAPP, AT+QIACT, AT+QILOCIP
Initialize TCP connection with AT+QIHEAD=1 and AT+QIOPEN=0,“TCP”,“infosatcentrale.ath.cx”,“9125”
Send Data with AT+QISEND=0,42
Receive Data; in details receive +QIRDI: 0,1,0 then I execute AT+QIRD=0,1,0,6
Send New Data with AT+QISEND=0,74; This data are received by server
The server sends data but I don’t receive the +QIRDI notification. The TCP connection is UP and the state is IP PROCESSING.

What could be the problem?

many thanks,
Giampietro

Dear Giampietro,
Thanks for your inquiry in Quectel forum.Please check the following answers to your question.
Firstly, the network signal in your test environment is no good, CSQ only have 15. Normally, it should large than 20 at least. Please check it.

Secondly, when you send data to server and check the results, the data still have not beed acked by server which means that it already have the network delay owing to the bad signal, then when you send data again, the data that you send last time still no beed acked finished. Please check the following picture.
So please confirm your test environment, then waitting for the server finished to ack the received data, then send data again to have a try. Thanks!
