Hi, my current firmware version is EC200AEUHAR01A12M16. I need older firmware versions, such as EC200AEUHAR01A03M08. I need a firmware released before mid-2022 to restore stability. Thank you in advance. sin.goddammit@gmail.com
It sounds like you’re dealing with some stability issues on your Quectel EC200A-EU module following a firmware update. The version you are currently running (EC200AEUHAR01A12M16) is indeed a later release, and rolling back to a stable 2022 version like EC200AEUHAR01A03M08 is a common troubleshooting step for IoT reliability.
