Beesure GPS  SeTracker Server Protocol

  ---Update time on Nov.13, 2023

Device System firmware software is Language C ;( per company regulation, not ok to open any port for device system bottom software developing)

App software language for IOS version is Object C,yet language for Android version is Java

The server language is Node. JS

key encryption is AES128, without MQTT
( per company regulation, you can purchase our key protocol )

IMPORTANT NOTE: Your server end should turn off Active in server setting, since our device bottom layer already with LK every 5-8 minutes for keep the network connection, if you set your server Active, it will often stop the LK connections from the device .This is main issue some clients configuration our device in their serve and it drain off the battery very fast!!!(If you can not find it in your server , please kindly search TCP Active in google, you will understand it )

****Server Protocol all GPRS Communications, with sim card through operator cellular network          

No any space in the command strings.

In the whole protocol all the command strings in the defined format of [manufacture*Device ID*content length*content]

*** the manufacturer defined two bit only, device ID is 10 numbers comes from the device IMEI ,IMEI registered in your server , the server identify the device per device ID number,the content length defined are 4 bit ASCII code, and the high digit bit forward and low digit bit afterward. from left to right,high digit bit  is on the left ,low digit bit is on the right. )

For example, ASCII FFFF means the length is 65535.

LEN is always change in each command string base on the correspondings content lenght , Example , length 162 in ASCII code is 00A2

For example:

Device send :

[SG*YYYYYYYYYY*LEN*LK,steps,sleep body tumbling number ,battery status percentage]



Note: Any string or command should start with [ and end with ],this is exactly comply even on server end TCP command .

IMEI number

I. Device send command

1. Link Keep ( heartbeat package)

(1) Device Send:



Server reply:



Note:Once connected with local network, the LK string will be send every 5-8 minutes, if the device not receive the reply from the server , then it will send the linkkeep every minute, after failure of connection 5 times, the device will reboot

(2) Device Send:

[CS*YYYYYYYYYY*LEN*LK,step,sleep body tumbling number,battery status percentage]


Server reply:



Note: Once connected network, the LK will be send every 5-8 minutes, if the device not receive the reply or confirm from the server , then it will send LK every minute, after failure of link 5 times, the device will auto reboot

【Both of upon (1)and (2)strings exist and valid】

Very important tip: The server must reply all LK command! Otherwise the device will not send any other data , it will keep on sending the LK command every minute. Because the LK command is the only one maintenance the network connection, it's handshake between device and server .

The most important is the device send whatever Linkkeep, your server need reply or confirm the Linkkeep for maintenance the network connection

At the beginning half hour , the device send the Linkkeep every minute ; after half hour , it send Linkkeep every 5-8minutes

This is handshakes between device and your server , so they know each other for keep the network connection, if not, the network disconnect;

2. Position data report

Device Send:

[CS*YYYYYYYYYY*LEN*UD, the position data (Refer to Appendix I)]

Example:[3G*9403094122*00CD*UD,180916,025723,A,22.570733,N,113.8626083,E,0.00,249.5,0.0,6,100,60,0,0,00000010,7,255,460,1,9529,21809,158,9529,63555,133,9529, 63554,129,9529,21405,126,9529,21242,124,9529,21151,120,9529,63556,119,0,40.7]


Data contents:

UD-network information


UD: that means the device is using 2G GSM network.

UD_WCDMA: that means the device is using 3G WCDMA network.

UD_LTE: that means the device is using 4G LTE network.)


025723-time(Greenwich meantime)(Hour/minute/second)

A-gps Positioning is valid (A or V: A means GPS location is valid; V means GPS location is invalid,please check LBS or WIFI location data, Google API need change to Latitude and longitude .)


N or S: North /South.


E or W: East / West.

0.00-Speed (for a personal GPS tracker, we don't have speed data , this speed almost is no reference value)

249.5-Direction (for a personal GPS tracker, this data almost is no reference value)

0.0-altitude (height above sea level, this data almost is no reference value.)

6-satellite numbers ( Effective)

100-gsm signal strength(Full is 100)

60-battery status ( Full is 100%)

0-pedometer ( Counting steps number)

0-tumbling times( Counting sleeping flipping)

00000010-the device status,The data is hexadecimal,convert it in binary system is 0000 0000 0000 0000 0000 0000 0001 0000

in the front of 4 bit of the string is status,the last 4 bit is alarm0001, the number is mean the device is static-unmoving.( Please refer to the appendix form for the meaning of each bit.)

7-local base station numbers

255,460,1,9529,21809,158,9529,63555,133,9529,63554,129,9529,21405,126,9529,21242,124,9529,21151,120,9529,63556,119,local base station information

0-WiFi number

40.7-positioning accuracy,it's meter


Server not reply.

(Note: this is the device send the realtime position report to the server )

Note: the Google API need change to Latitude and longitude for indoors position from LBS or wifi

Note: The device reports the location and status information according to the set interval, the server not reply.except in sleep save power mode, but if the device gravity sensor detect any shaking or moving from different orientation , it will activate immediately and syncs the data per the defaulted setting time interval ,if no any manual request or server request.

( Note: the number of UD strings just base on the existing firmware software setting, some RT OS /CAT 1 device only 1 UD string after CR command)

more detail information , please kindly refer to configuration guide in our company website :
