bluetooth.afh_map

type: getvar. setvar

Sets or retrieves default AFH channel map (Bluetooth 1.2 radios only); 20 bytes.

The AFH map must be 20 characters long; for Zebra printers. All characters used are HEX characters. 20

HEX characters used for AFH channel map form 80 bits binary channel map that represents 79 channels

used by Bluetooth (the first bit is masked out automatically by the Bluetooth library). Each bit defines a 1

MHz Bluetooth channel state that will be used to generate the AFH channel map where 1 marks a channel

as “good” and 0 marks a channel as “bad” (not to be used by Bluetooth radio).The rightmost bit defines

channel 0 and the leftmost bit defines channel 79. This map is passed to the Bluetooth radio installed in

Zebra printer when AFH mode is ON.

NOTE: Default AFH Channel Map value is set to enable all 79 Bluetooth channels.
