I'm testing the Earfun Air Pro 3 with an LE Audio device we are developing and just updated to the latest firmware. 0.4.2. It appears that LE Audio has been removed as sinks are no longer being reported. Is there any way to downgrade to earlier firmware with LE Audio support or get access to newer development firmware to test with?
Hi friend,
Thanks for choosing EarFun.
In LE Audio mode, we found that the mobile phone will actively disconnect the earbuds, resulting in no sound from the earbuds. The LE Audio function of our earbuds is fine, but it is a protocol problem on the mobile phone side. In order to solve this problem, we can only disable LE Audio in the latest firmware. After the problem on the mobile phone is resolved, this function will be enabled through a firmware upgrade.
If you want the previous firmware, please email our customer service team via service@myearfun.com.
Sorry for the inconvenience caused. Thanks for your understanding.
Sincerely,
EarFun Customer Service Team
I managed to downgrade by mitm the connection and forcing another version. I tried the 0.3.8. still the same problem, no LE Audio. I flashed some versions, no luck. there's no LE Audio at all. why ?
firmwares are here : https://app.myearfun.com/ota/get_Ota_list.efbs
So even with previous firmware I can't get LE Audio to work anymore. Why ?
