1. Common Basic Troubleshooting Steps β–Ό
  1. First send command PARAM# to make sure SMS command is working or not.
    If not getting the reply of SMS command then need to check SIM card or installation to make sure device is connected to power.
    If getting SMS reply but device is not coming online on server then follow below steps:
  2. status# and check# and APN# – make sure APN is correct
    Example: APN,airteliot.com#
    In status# reply:
    GPRS:link UP means device is connected to server.
    GPRS:link DOWN means device is not connected to server.
    Possible reasons: wrong APN, wrong server command, network issue, server response issue, or server port issue.
  3. In check# reply:
    • If GPRS status is showing 0 means internet is not working
    • If showing 1 means working
    • If using URL/Domain in server configuration then check GET IP – if show 0.0.0.0 means internet is not working

  4. If showing "searching satellite" then check where# first. In where reply you can check last fixed GPS date.

    In status# reply if satellite status is like 0(24) or 0(4) means location issue or installation place (mounting) issue. To cross check this issue please move the vehicle and in moving condition check status#. If in moving also showing searching satellite like 0(24) then need to check installation place.

    Second case "UART NO DATA".
    If showing "UART NO DATA" in moving condition also then hardware issue – need to send back the device.

    Application to check Satellite signal status: GPS Test on Play Store

  5. Recently, we have found an issue with a few vehicles. After connecting the device to the vehicle battery or turning the ignition on, the GPS is not able to get a fix. This is due to electromagnetic interference.

    6. We suspect that this is caused by an interference source. Since this problem has emerged recently, please first check if any new devices have been installed in the vehicle, such as Bluetooth speakers, etc., which might cause electromagnetic interference to the tracker.

    If you can obtain the tracker, you can take it outside for testing to see if the positioning works well when the ACC is turned ON.
    If in status# reply showing "GPS:ON, Uart no data;" in moving showing the same – that means hardware issue & need to send back the device to Markon office.

If still facing issue:
  1. Shift the non-AIS device to this server: server,1,gps.markongps.com,21100,0#
  2. Wait for 2 minutes then check status# again & cross check GPRS status
  3. If showing GPRS link up that means device is working fine & maybe your server port issue/Wrong response/Protocol integration issue etc.. & need to check with your software provider

If showing GPRS link:up but still device is not coming online then send following commands & then check the data:

. gpsdup,on# . fdrift,off# . timer,10,10# . acc,on,0# . reset,1#
After above commands: If still device is offline and showing GPRS link down then please share the only raw data with device IMEI, raw data sample (decoded data not required, required only Hex logs).
78 78 05 15 00 49 F1 64 0D 0A 78 78 0A 13 46 06 04 00 02 00 4A 76 B8 0D 0A 78 78 05 13 00 4A 15 26 0D 0A 78 78 0A 13 46 06 04 00 02 00 4B 67 31 0D 0A
If Showing wrong location on server: please check use following command to check GPS status

1. status# (make sure GPS is fixed and GPRS link is UP)

2. URL# (using this command you will get the current location and then you can match the location with server location)

3. where# (using this command you will get current lat, lng with speed value)
2. Sleep Mode: What is sleep mode & How it works? β–Ό

Sleep Mode

What is Sleep mode?

Answer: Once ignition is off, device will go in sleep mode after 5 minutes. In sleep mode device will send heartbeat packet as per configured interval & information packet.

In sleep mode only GPS module will be off to save the vehicle battery and data.

Enable Sleep Mode

SENDS,5# – What does "SENDS" command do?
sends command controls the GPS module. If sends is 5 that means once ignition is off then in next 5 minutes GPS module will enter sleep mode (GSM module will keep working) and device will send only HBT packet to server. Once ignition is on, device will exit the sleep mode and keep sending location data normally.

Recommended commands for sleep mode:

1. gpsdup,off# (For data when ignition is off or GPS is not fixed) 2. sends,5# 3. hbt,1,1# 4. timer,10,3600# (timer is for location packet interval) 5. sf,on# (sf static filter for static drift) 6. fdrift,on# (fdrift is filter for speed drift)

Disable Sleep Mode

After these commands no matter ignition is on or off, device will always send the data (maybe in static you can face static drift issue).
1. sends,0# (GPS module will be always on) 2. gpsdup,on# 3. sf,off# 4. hbt,1,1# 5. timer,10,10# 6. sf,on# 7. fdrift,off#
3. Mandatory URLs / Application / Communication Protocol for Data Whitelisting β–Ό

These servers should be whitelisted:

  1. fota.markongps.in and 43.205.18.220 – OTA server, need to whitelist both URL and IP (reason: sometime Operator is not able to resolve the DNS address, due to this issue need to whitelist both address IP and URL)
  2. gpsdev.markongps.in & 94.136.186.76 – testing server1 for troubleshooting (mandatory only for testing purpose else ignore this one)
  3. test.markongps.in & 217.216.78.62 – testing server2 for troubleshooting (mandatory only for testing purpose else ignore this one)
  4. Communication Protocols: TCP, HTTP, FTP, UDP, SSL, PAYLOAD, EXISTING, SIP, SMTP, RTMP, SSH, HTTPPROXY
  5. Application Protocols: Google Maps, Google APIs, AMAZONAWS, AMAZON, Others, Bittorrent, Google Cloud Messaging, Encrypted Client, Microsoft, Google, DTLS
  6. Where to find Application & Communication Protocols (example: with Airtel M2M Portal): in side menu find β†’ Rule center β†’ Data whitelisting β†’ Edit APN configuration β†’ then under the action table title, click on pencil edit button
    7. Airtel M2M Portal screenshot

Recently, we have observed some issues with Airtel M2M SIM cards.

If the data flow shows Login β†’ HBT packet β†’ connection disconnects, and then again Login β†’ HBT packet, this indicates a whitelisting issue. Because the data connection drops within milliseconds, the device is unable to upload the location packet. Due to this, the latest location will not be updated on the server.

You can check the current location using the URL# or WHERE# SMS command. (For more details, please contact: support@markongps.com)

Note: We have observed that this issue may affect approximately 30%–40% of devices.

We have conducted multiple meetings with the Airtel team, and after applying the recommended configuration, the issue is getting resolved.

If you are still facing the same issue, please raise a complaint with Airtel stating: "Facing data disconnection issue within milliseconds." Once you receive the meeting link from Airtel, please include our support team (support@markongps.com). Our team will assist in explaining the issue to Airtel.

Important: Before raising the issue, please ensure that the testing URL is whitelisted.
4. Wetrack140 FAQ β–Ό
  1. In Wetrack140 do not configure APN or GMT, APN and GMT will be configured automatically. To reset the APN configuration use: ASETAPN,ON#
    Default APN is TAISYSNET for Taisys & SENSEM2M2 for Sensorise.
    Important Note: After reactivation of eSIM need to send clear# and reset,1# command to clear older data.
  2. Planumber (vehicle number) should be correct otherwise it will create issue in govt. backend portal.

    Default planumber is: planumber,000000000#
    Query current parameter: planumber#
    In NIC backend portal please configure vehicle number example: planumber,AB12C1516#

MAHAKHANIZ Ports for Markon

Command Example: backupserver,1,mh.markongps.in,18009,0#

If device is not updating on MH mining portal then:

Required configuration:
1. sends,0#
2. sf,off#
3. gpsdup,on#
4. timer,10,10#

  1. Check backupserver# and status#
  2. In status# reply GPS should be fixed; if GPS not fixed then mining server will reject the data.
  3. If showing "searching satellite" then move the vehicle and check status#

    Example of GPS not fixed: Battery:4.03V,NORMAL; GPRS:Link Up; Signal Level:Strong; GPS:Successful positioning; SVS Used in fix:0(36); (OR 0(0))

    Example of FIXED GPS: Battery:4.03V,NORMAL; GPRS:Link Up; Signal Level:Strong; GPS:Successful positioning; SVS Used in fix:24(36);
  4. If still showing "searching satellite" then need to check installation place of device
  5. In backupserver# reply cross check the mining URL and port
  6. Last command reset,1#; after command wait for 10 minutes and then check the data on MH mining portal
Note: After all above troubleshooting if still device is not updating then share (support team refer point no.18) the device IMEI and MH mining portal snapshot where last update is visible with date and time.

GPSDUP Command

(basically gpsdup command copies last fixed location & keeps sending with updated date and time when ignition is off or when GPS is not fixed – once ignition on and GPS is fixed then command has no impact)

GPSDUP,A#
A=ON: Regularly upload data when tracker's ignition is OFF or vehicle static
A=OFF: No location data is uploaded when ignition off, sleeps or static. Default: OFF
Query current parameter: GPSDUP#
Example: GPSDUP,ON#
Reply: OK!

SF "Static Data Filtering"

Use case: SF command helps to avoid static jumps when vehicle is in parking. Example if value is SF,on,100# then in this case if ignition off and any static jump found within 100 meter then device will not upload that false data to server.

SF,[A][,B]#
A=ON/OFF; static drift filtering switch; default: ON
B=10-1000(m); maximal filtering distance; default: 100(m);
Query current parameter: SF#
Example: SF,ON,100#
Reply: OK!

FDRIFT "Speed Data Filtering"

Use case: if vehicle is moving with slow speed in narrow streets and not getting the data on server as per configured timer interval or moving is not clear then use "FDRIFT,off#" command and test one more time.

FDRIFT,[A][,B]#
A=ON/OFF; speed drift filtering switch; default: ON
B=10-1000(m); maximal filtering distance; default: 100(m);
Query current parameter: Fdrift#
Example: Fdrift,ON,1000#
Reply: OK!
Note: If vehicle is moving with slow speed (5 or 10 Km/h) & device is not uploading location data like E-riksaw then use fdrift,off#.
13. History Data Clear Command β–Ό
