Hi,
I am using MC60CA.
I need to update signal strength along with other data to server.
AT+CSQ returns +CSQ: 19,0 before opening TCP Connection through AT+QIOPEN.
But after TCP connection is established, AT+CSQ does not respond anything.
Dear Suman,
Thanks for your inquiry in Quectel forum.
Could you help to provide your test AT log to us, then we can help to confirm your issue. Normally, you should waiting for receive the response of the command AT+QIOPEN, then send AT+CSQ. Thanks!
AT+QIOPEN=“TCP”,“xxx.x.x.x”,“xxxx”
/ Actual IP and Port are intentionally replaced with “xxx.x.x.x”,“xxxx” to not reveal here and to post querry on discussoin forum /
Dear Suman,
Please make sure whether your UART connection have any abnormal, the following is my test log, please check. It have no any issue. Thanks!
For your issue, please check the serial port connection, and change another module to have a try, or change another connection cable, or you can check it with Quectel EVB board. Thanks!
Hi Kyson, it was UART issue.
Moreover, i am starting to work with OpenCPU with MC60. Can you send me “sourcery codebench lite” intaller for windows platform.
Please send me other docs/software required for this.
