Latest Firmware Version

IoT Modules LTE Standard Module
1

Hello,

I’m using a quectel EC200U which reports the following firmware version :

→ ATI
← Quectel
← EC200U
← Revision: EC200UCNAAR03A03M08

The response formats don’t always match the documentation / application notes, for example :

→ AT+QHTTPURL=23
← CONNECT
→ http://www.example.com
← OK
→ AT+QHTTPGET
← OK
← +QHTTPGET: 714

Here, I expect httpget to return 3 numbers in the response. I’m further not able to actually read the response, because HTTPREAD just says ERROR

Could you please help me with the following:

  • What is the latest firmware revision for EC200U-CN
  • What is the firmware revision the Application Notes are written against
  • What is the best place to get documentation for the AT commands

Thanks

This is what I get for AT+CVERSION:

-> AT+CVERSION
<- VERSION: EC200UCNAAR03A03M08
<- Dec 15 2022 21:48:05
<- Authors: QCT

This is an EC200UCNAS-N05-SNNSA. Can you also please send me a copy of the latest firmware, and is there a place this can be downloaded from instead of asking for one here?
