        Hi IOT747 Support,

        I’m currently using an IDC777-1 module on a Mikroe BT Audio 4 Click board (MIKROE-6685), running AudioAgent V3.1.70 (build 0400427b).

        I’d like to upgrade to the latest stable firmware (AA3170D), but before doing so I’d like to have the V3.1.70 firmware file available as a rollback in case the upgrade causes any compatibility issues with the Mikroe board hardware.

        Could you please provide the V3.1.70 (build 0400427b) firmware file so I have it as a safety net before proceeding with the upgrade?

        Also, are there any known compatibility issues between AA3170D and the Mikroe BT Audio 4 Click board that I should be aware of before upgrading?

        Thanks in advance for your help.

        Best regards,

        Denis

          Hi Denis,

          It seems like there is a typo in your email. You are upgrading from what firmware version to AA3170D.

          But there is no issues, we suggest you upgrade to AA3170D or even the latest firmware for more functionalities. If the firmware was working on one board, an upgrade will still work on that board. So you can go ahead and upgrade.
