RoadRunners – Communication Protocol
When setting only MinSniff and MaxSniff values, the default value 0x08 will be used for Sniff attempts
and Sniff timeout.
Typically values:
Full speed (full power)
MinSniff = 0
MaxSniff = 0
Low Power: (sniff of 500ms Only) (low speed)
MinSniff = 0x0320
MaxSniff = 0x0320
Low Power: (sniff between 250ms to 500ms are acepted) (low speed)
MinSniff = 0x0160
MaxSniff = 0x0320
MaxSniff and MinSniff are only used for sniff negociation. If both sides allow sniff value MaxSniff, then
MaxSniff will be used. If the other side does not accept Sniff values MinSniff to MaxSniff, no sniff will
be used.
Values are in number of Bluetooth slots (1 slot = 625µs)
Set MinSniff and MaxSniff to 0 to disable Sniff.
MinSniff must be inferior to MaxSniff.
Possible values for MinSniff and MaxSniff are 0x12 to 0xFF.
Sniff attempts of 0 is not allowed.
Warning: Setting MaxSniff to 0xFF means a sniff period of 40s! You will have very very low data rate.
Also, setting MinSniff to 0x12 means that you will have 0x12 Bluetooth slots to transmit data.
Note: This setting takes effect immediately.
