Mictrack MT700 + Battery Voltage

fmoses4 years ago

Hello, I am using the MT700 devices from Mictrack and they are working to the TLT2H port at the moment. But the devices send the battery voltage string but that's not in the TLT2H decoder it looks like. If i hexdecode the raw data I see the battery voltage but traccar itself isn't.

Mictrack provides a protocal data sheet:
https://www.mictrack.com/downloads/protocols/Mictrack_Communication_Protocol_For_MT700_V1.0.pdf

Example string:

#38$GPRMC,105721.00,A,2238.3071,N,11401.7575,E,,96.70,250321,,,A*74

the #38 is 3.8volts

If it is not to much trouble can this get ether added to the TLT2H decoder or a fresh decoder added for the MT700 devices please.

Thanks,

Hi Fredric,

Anton will help integrate MT700 on traccar and it may release soon in the next traccar version.

Great to hear. Our testing so far has been good with the units... Not that I had any doubts. First event for them to get used at is in a few weeks and the battery life is just great. One minute updates and it ran for just over two weeks with LTE-M. Most events are 2-3 days so can turn the devices on during the setup the day prior and not worry about them till clean up a few days later.

Hi Fredric,

Thanks for your feedback.
You may test on Mode 1, Mode 1 the power consumption is the biggest because the Network and GPS will always on.

As our actual test in Mode 3 the standby current is less than 1.5uA and this is the video for the test.

So there is an issue with the new version, Just upgraded and the MT700's are all throwing:

error - NullPointerException (FilterHandler:84 < *:161 < *:200 < BaseDataHandler:27 < ... < *:29 < ... < ExtendedObjectDecoder:61 < ...)

I will open an issue on github.
