it would be useful if you could post your bthidd(8) configuration entry 
for the wii controller.

please take a look at the "reconnect_initiate" parameter in the wii 
controller configuration entry (in bthidd.conf). usually, bluetooth hid 
devices have this parameter set to "true", which means that hid device 
itself will initiate connect after it was disconnected. usually, one can 
press a button or move the device to wake it up and re-connect.

bthidd(8) will only initiate connection to the "new" hid devices. "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.

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,
