We are currently working with the Quectel EG91-NAX module running the following firmware:
EG91NAXDGAR07A01M1G_01.001.01.001
During our testing, we observed that when the QMI service is stopped or restarted, the GNSS/GPS data output stops or becomes unresponsive until the module is fully power‑cycled. We would like to confirm whether this behavior is:
- A known issue in this firmware version
- Expected behavior due to internal subsystem interactions
- Already addressed in a newer firmware release
- Related to any specific configuration or command sequence
Could you please provide the following information:
• Whether this firmware version has any known GPS/QMI interaction issues
• Any recommended firmware update or patch that resolves this behavior
• Best‑practice guidelines for stopping or restarting QMI without impacting GNSS
• Any diagnostic commands or logs you would like us to collect for further analysis
We are happy to provide additional logs, AT command traces, or reproduce the issue if needed.
