1.1.24 accinfo
SMS message is used to check if accelerometer is calibrated for eco-driving functionality. Only state information
is should be interpreted.
Parameter Description
State 0 – not calibrated
1 – calibration started
2 – zero position calibration is in progress
3 – forward movement calibration paused
4 – forward calibration
5 – forward calibration in progress
6 – forward calibration in progress
11 – calibrated
XYZo, Xc, Yc, Zc Parameters used for accelerometer events' calculations.
Example: pass accinfo
Response example: AXL state:11 XYZo:120 -39 -945 Xc:131 -92 -94 -7 Yc:-138 97 -96 16 Zc:953 120 -39 -945
Note
There is an exception for the FM-Plug4. Response example for this device:
AXL state:11; XYZo:0.0,0.0,1.0; N:-0.023; ABC:-0.15,0.9,0.32; N_:0.8; A_B_C_:1.24,-0.42,0.6
1.1.25 accreset
SMS message is used to reset accelerometer (used for eco-driving functionality) calibration.
Example: pass accreset
Response example: Acc reset OK
Additional parameter can be included in the main SMS command which will initiate a new calibrationprocess
and inform the user of the ongoing calibration status:
Example: pass accreset r
Response example if conditions are correct to start calibration: Stationary calibration in progress;
Response example if “Eco-Drive”, “Accident detection” or “Rollover detection” functionalities are disabled:
Configuration error;
Afterwards the device will send SMS messages based on the calibration status:
“Stop the car for stationary position calibration” - if the vehicle was moving when the “accreset r” command was
received by the FM device
“Stationary position calibrated. Start Accelerating” - is sent after the stationary position is calibrated.
