Battery level from TOPIN devices

Hi ALL,

I am using devices from topin manufactory. I am not able to display on the web ui the battery percent of the device. I set it to port 5199

In my traccar log i can see this status package :

7878071335040819640d0a

Following to the protocol :

0x13 status package

Device sent data to the server

Start bit 2byte Reserved byte 1byte Protocol number 1byte Battery power 1byte Software version 1byte Time zone 1byte Status packet upload interval 1byte End bit 2byte
Eg.7878 06 13 55 23 08 03 0D0A

55 indicates that the battery power is still 85%, 23 indicates that the software version number is 35 08 indicates that it is East 8 (just an integer), and 03 indicates that the status packet upload interval is 3 minutes.
Increased signal strength
Start bit 2byte Packet length 1byte Protocol number 1byte Battery power 1byte Software version 1byte Time zone 1byte Status packet upload interval 1byte Device signal strength 1byte End bit 2byte
Eg.7878 07 13 55 23 08 03 64 0D0A
0x55 indicates that the battery level is 85. 0x64 indicates device signal strength 100

So in my case the interrested data byte is 35 but the percent is not displayed.

I have set server side in the popup informations battery, battery level, and voltage ...

Anyone to help me to solve this problem ?

regards

It's already supported:

https://github.com/traccar/traccar/blob/master/src/main/java/org/traccar/protocol/TopinProtocolDecoder.java#L202

If you don't see it, either your device is not reporting it or maybe it reports some other message type and that's what you're looking at.

I confirm, I have 18 active Topin and the battery level is displayed randomly even though it is sent, I don't know why, because the battery level is not important at the moment .for exemple :

It is shown when you device sends it.

even if it's not a problem for me at the moment, because I'm testing something else, I can just say that it's not automatic, sometimes yes sometimes no, while the command is sent, I bring just an experience.

Topin has many products, in my case I use the 2G model and sometimes it does not show the battery level, I suspect that they modified their protocol because it does not show me the speed in the graphics of my routes. (all this with the best antenna for 930Mhz and other to 1800Mhz for 2G)

Hi all,

Thanks for your explanation. But as you can see below in every status package the battery level is in it but not displayed :

I have made a space between hex data to show the number 35, this is battery level.

below the last protocol of TOPIN DEVICES :

LAST TOPIN PROTOCOL

Anton would you please check the protocol to be sure everything is okay ?

I already checked before, but you don't listen to what I'm saying.

I am with Anton, it is not traccar failure or protocols. Right now I have 2 GPS of the same model, one online and one without line since yesterday, both on the map, click on the without line and battery level 95%, click on is online and no there is a battery level but yes show there is RSSI and some others attributes. These Chinese GPS do a little what they want.

After last checks unfortunately the battery level only appears when the device is offline.
