I bought this lovely little tracker for just under 20 euros. Which is a great fit for tracking the whereabouts of my new bicycle. It is tiny, it has some protection against the weather, a decent battery life and a magnet. The only bummer was: There were no oldskool SMS commands. Only a sleezy looking app which told me that my tracker would expire within a year. Traccar was my way to go, as it allowed me to keep my privacy and to stop the addition of more e-waste.
I knew it supported SMS commands as it responded to random gibberish with: "Invalid sms cmd". Using Google-fu a few sources which hinted at the possibility of a few SMS commands. Based of a half translated command list and the spec sheet of the protocol I created this list. Please note that I still do not completely understand what parameters are available and what each command does.
For a typical Traccar setup I recommend sending (setting the APN is optional):
- SL FT
- SL APN{myapn.com},{APN username}, {APN password}
- SL DP{mydomain.com or IP address}#5015#
- SL CP{your international phone number}
Afterwards simply add a new device to Traccer and fill in the serialnumber of the device prefixed by a 0 (for example S\N: 16324..., will be device ID: 016324.)
All commands:
| SMS command | SMS format | Function | Notes | Example | Response |
|---|---|---|---|---|---|
| 1 | SL MT{Telephone number}# | Listen directly to recorded audio. | If this is not supported it will simple respond with:Set OK! | SL MT10086# | |
| 2 | SL LC | Get current location as Google Maps link. | Will return: GPS IS NOT READY, when the signal has been lost. | SL LC | Google Maps url |
| 3 | SL FT | Factory reset device. | It does not reset the server configuration nor the APN configuration. | SL FT | Reset to factory Set OK! |
| 4 | SL RT | Restart device. | SL RT | Restart Set OK! | |
| 5 | SL DP{IP or domain name}#{port number}# | Switch to another server supporting the Huabao-protocol. For example connect to a Traccar server on port 5015. | When adding the device to Traccar append a 0 before the device ID. | SL DP192.168.1.1#5055# OR SL DPexample.com#5055# | Set ok!IP:192.168.1.1 5055 |
| 6 | SL XM | Set the device to sleep. | SL XM | ||
| 7 | SL HX | Wake the device up. | SL HX | ||
| 8 | SL CP{NO.+#) | Change the controlnumber of the device. After setting this up the device will only respond the SMS messages from this number. | Please fill in the complete international number. Always send SMS messages to the international number of the tracker. I am currently unsure if there is a hardware reset button. So be carefull! | SL CP | Set OK!CenterNumber:.. |
| 9 | SL CX | Returns the: Device ID; Server host; Server port; APN host; Unknown; Unknown ; Battery level | SL CX | ||
| 10 | SL MODE{Positioning mode}, {short connection interval}, {whether to enable flight mode}, {short connection duration} | Set the device positioning mode. First parameter: the power savings mode: - 1: Normal mode (real time tracking): Uploads data every 5 minutes, - 2: Uses the settings of the periodic positioning mode, - 3: Smart power save mode, - 4: Super power save mode. Third: Flight mode, 1 to enable and 0 to disable, Fourth parameter: The amount of minutes till standby after having not registered any movement. |

Thank you so much, I've been looking for this for a few days now.
