bluetooth.afh_map_curr
type: getvar
Retrieves the current AFH channel map (may be different from default AFH channel map)
The current AFH channel map is 20 HEX characters long and represents a bit-mapped channel map
for 79 Bluetooth channels; each bit defines a 1 MHz Bluetooth channel. Zebra printers with collocated
Bluetooth and Wi-Fi radios should have the current AFH channel map different from the default AFH
channel map because the Bluetooth library constantly adjusts Bluetooth AFH channels and Wi-Fi channels
to eliminate interference between the radios. In systems without collocated Bluetooth and 802.11 b/g
radios this parameter returns a channel map identical to user-defined AFH Channel Map (“bluetooth.afh_
map”).
getvar result 20 bytes string of HEX characters
Example 1
Description Retrieves current AFH channel map
Syntax ! U1 getvar “bluetooth.afh_map_curr”
Result “0000000000FFFFFFFFFF”
Example 2
