AT+BLEHID - FWD and BACK buttons isn't working

[bartoszp1992]

Hi!

I'm initializing HID with success. My main mouse buttons are working perfectly, as also entire keyboard. But I have problem with BCK and FWD buttons.

AT+BLEHIDINIT=1
AT+BLEHIDMUS=*,0,0,0

When * are:
1<<0 LMB
1<<1 RMB
1<<2 MMB
1<<3 any reaction
1<<4 any reaction
1<<5 any reaction
1<<6 any reaction
1<<7 any reaction

I check it on my android device, and also on my computer(fedora, with wev program). When using other buttons except 3 main, i havent receive any HID keys. Why?
It's descriptors problem?
Where in AT firmware(im using compiled by myself firmware) i can change descriptor for mouse?
