Mouse BTN4/BTN5 not working in bluetooth mode #322
I beleive you can send only 3 buttons with RN42 bluetooth module, though I cannot find clear reference in their documents. Also you cannot use horizontal wheel in BT mode.
This is limitation of the module so there is no fix.
EDIT: See report descriptor below, you can confirm that mouse sends only three buttons.
Just for future reference.
