@DUDU-Meng for now, i dont found a problem but i want to ask if my MCU version is too old or not , does it will be ok with upcoming version 3.8 . Should i update mcu version to the latest 260529

DUDU-Meng

jacob If there is no problem with the use, you can choose not to update the MCU, and the update system will not require the MCU to be updated.

DUDU-Meng Yes, meant the "snapping sound of the power amplifier when it is turned off". Will try the ACC delay to 5 seconds, and let you know. Thanks.

A huge thank you! With this version (s3-dudu7-mcu-260529), I got the hands-free opening and closing back on my trunk (2021 Peugeot 3008 PHEV). You're doing fantastic work!

@DUDU-Meng , so, this worked the opposite way around. I had originally set 2 seconds delay for power amplifier, tried 5 seconds and did the same snapping sound. Set it to 0 seconds and voila, snapping sound gone. Solved.

I have 1 more question, maybe I should start another discussion? When the DUDU 7 is in sleep mode, the ANT Power 12V+ (Pin 8 on Power Supply connector) does nor power down. It is continuously 12V+. Is this normal in sleep mode?

DUDU-Meng

dranias Yes, it won't power off.

DUDU-Meng One more question. After the MCU update, my FM reception has become very bad. Checked Antenna, Ant Power 12V is ok. FM reception was super strong before the MCU update. Can the MCU update have effected the FM reception?

DUDU-Meng

dranias I don't think there's a connection here, but you could try downgrading to a previous version of the MCU to verify this.

DUDU-Meng Ok, can you provide me the original MCU I had to test this out, version 2024.01.24. Thanks again.
