Hi, guys. First of all sorry for english. Unfortunately, I don't speak Chinese. But hope someone will understand me :)
I've bought headphones based on CSR8645 chip (if it does matter - Major II Bluetooth from aliexpress). Connected them via SPI and trying to enable battery reporting service.
Once I set USR9 PSKey from PSTool leds stopped to work and iPhone couldn't connect to headphones anymore. When I change USR9 to my default value (for me it's 0000 0001 0006 0008 0003 000d 0000 0000 000b 0f0f) - leds becomes work and iPhone connects again but battery still doesn't appear on phone
Could it be fixed?
ok, posting some changes. tried no to change events WORDS. now I have 000b 0005 0006 0008 0003 000d 0000 0000 0055 0f0f setted in my USR9 key. USR3 key leave he same as in this post. but battery status doesn't appear on my phone :(
finally figured out this stuff :)
seems to be I was needed to "forget device" and re-pair headphones once again. now battery is displaying on iPhone. the only problem is percentage is wrong. I have 650mAh battery and it fully charged. my phone shows 60%
changed usr3 to
3404 3405 1a05 2105 AD05 4105 5305 0000 002b 004d 0049 0043 0054 0045 0053 0054 0000 004f 004b 000d 0000 002b 0058 0041 0050 004c 003d 0069 0050 0068 006f 006e 0065 002c 0037 0000 004f 004b 000d 0000 0041 0054 002b 0058 0041 0050 004c 003d 0030 0030 0030 0030 002d 0030 0030 0030 0030 002d 0030 0031 0030 0030 002c 0037 000d 0000 0041 0054 002b 0049 0050 0048 004f 004e 0045 0041 0043 0043 0045 0056 003d 0032 002c 0031 002c 0082 002c 0032 002c 0030 000d 0000 0000
(replaced 0081 with 0082)
