woops, reply to myself… I’ve forgot to save the baud change… it was 9800 ..
ok, another pb now: I’ve sent the bk_play cmd. the bonsai drive start to browse thru all menus like crazy… so, I sent the bk_release right after that…. but nothing change ? the bonsai drive keep browsing thru menus…??
I can make it play, stop, etc.. al transsport fonctions are fine.
