!LEDCTRL
Supporting chipsets:
• All, with these exceptions:
• MSM6290 (min f/w rev:
K1_1_0_5ap)
Note: MDM6200, MDM6270,
MSM6290, and QSC6270
include <invert> parameter.
Set/report LED control pattern
Control the pattern-flashing behavior of the LED. See the device’s Product Specification
or Product Technical Specification document for default behavior.
Usage:
• Execution: AT!LEDCTRL=<index>, <period>,<ontime>,<invert>
Response:
OK
Purpose: Set the LED behavior for the indicated pattern and indicate if the on/
off pattern should be inverted.
Note: <invert> may not be available on some chipsets.
• Query: AT!LEDCTRL?
Response:
<index1>:<period>,<ontime>,<invert>
...
<indexn>:<period>,<ontime>,<invert>
Purpose: Return a list of supported patterns.
Note: <invert> may not be available on some chipsets.
Parameters:
<index> (Pattern number)
• 0 = OFF pattern
• 1 = Searching for service
• 2 = Attached to network
• 3 = Connected (has an active context)
• 4 = Low power (airplane) mode
• 5 = Connected and transferring data (has an active context, and packet switched
data is being passed).
<period> (Length of repeating pattern)
• <period> ≥ <ontime>
• Unit of measurement: 100 ms
<ontime> (LED stays on for this amount of time per <period>)
• <ontime> ≤ <period>
• Unit of measurement: 100 ms
<invert> (Keep or reverse the on/off LED pattern)
• 0 = Display normal LED pattern
• 1 = Invert the LED pattern (<period> - <ontime>).
For example, if the LED is normally on for 50 ms and off for 25 ms, it is now off
for 50 ms and on for 25 ms.
Examples:
• AT!LEDCTRL=1,52,50
While searching for a network, the LED stays on for 5 seconds out of every
5.2 seconds.
• AT!LEDCTRL=3,5,4
While in a call, the LED stays on for 0.4 seconds out of every 0.5 seconds.
• AT!LEDCTRL=3,5,4,0
Same behavior. LED stays on for 0.4 seconds out of every 0.5 seconds.
• AT!LEDCTRL=3,5,4,1
Invert the LED behavior. The LED stays off for 0.4 out of every 0.5 seconds.
