9.5.1.1
AT ECO BLK
This command queries (
AT ECO BLK ?
) or determines
(
AT ECO BLK = <channel map>
) which radio frequencies the WSA may
use for data transmission.
The value represents a channel map for the 79 possible
Bluetooth
®
channels where
each channel is encoded as a bit starting with the lowest.
For value
ff.ff.ff.ff.ff.ff.ff.ff.ff.f7
all channels are allowed.
For example, 16 channels at the lower end of the frequency band are blocked with
value
00.00.ff.ff.ff.ff.ff.ff.ff.f7
.
Example:
AT ECO BLK = 00.00.ff.ff.ff.ff.ff.ff.ff.f7
9.5.1.2
AT ECO BLK 15.4 = <Channels>
The
AT ECO BLK 15.4 = <channels>
command adds more channel
frequencies to the list of blocked radio frequencies in accordance with IEEE
802.15.4.
With each channel blocked in this manner, a range of 5 MHz around the center
frequency is blocked in the channel map. Up to 9 individual channels separated by
commas can be specified per command.
Example:
AT ECO BLK 15.4 = 2,8
blocks the frequency ranges for channels 2 and 8.
9.5.1.3
AT ECO BLK BT <Channels>
The
AT ECO BLK BT <channels>
command adds more channel frequencies
to the list of blocked radio frequencies in accordance with IEEE 802.15.1.
With each channel blocked in this manner, a range of 1 MHz around the center
frequency is blocked in the channel map. Up to 9 channel ranges separated by
commas can be specified per command.
Example:
AT ECO BLK BT 10-10, 20-22
blocks the frequency ranges for channels 10, 20, 21 and 22.
9.5.1.4
AT ECO BLK WIFI = <Channels>
The
AT ECO BLK WIFI = <channels>
command adds more channel
frequencies to the list of blocked radio frequencies in accordance with IEEE
802.11 b/g.
With each channel blocked in this manner, a range of 25 MHz around the center
frequency is blocked in the channel map. Up to 2 individual channels separated by
commas can be specified per command.
Example:
AT ECO BLK WIFI = 6
blocks the frequency range for channel 6.
