"new" means that bthidd(8) had never established connection to this device before (in other words the device'd bd_addr is not listed in the "known hids" file). once device is "known" to bthidd(8), it will use the "reconnect_initiate" parameter to see if connection should be initiated to the device or if it should simply wait for the device to connect. > 2. How do we send HID request to Wii controller? > Some sensors, like accelaration sensor and nunchaku and player identifier > LED should be activated by request from host. since it is a hid device, all you need to do is to fill out and send hid report. hid descriptor will tell you which reports device can send and which reports it will accept. it will also tell you acceptable ranges for values etc. please use % bthidcontrol -a BD_ADDR_of_the_wii_remote dump you could also take a look at bthidd(8) code that sets keyboard leds in /usr/src/usr.sbin/bluetooth/bthidd/kbd.c please see kbd_status_changed() function. thanks, max
