I bought two of the SenseCAP T1000 E Trackers and have them flashed with the latest Meshtastic Firmware. The issue I am having is that they are both showing their position to be almost a mile away from where they are actually located. I am using them with my iPhone and iPad. When viewing the Mesh Map screen I can see my other HelTec V3 and RAKWireless nodes and they are displaying at the correct location on the map.
I have looked and looked in the settings and configuration screens and can find nothing that will make these two T1000 E show their correct GPS locations on the map. This makes them useless for a Tracking device.
What am I missing?
In the screenshot both T1000 E trackers are displaying on top of each other, almost a mile to the left of where their actual location is, (the other node to the right) is where they should be showing up at.
Hey Keith! I had a similar problem when I first set up my devices, and here’s what I found helpful.
First, ensure that the trackers have a clear view of the sky for optimal GPS signal reception. If they are indoors or obstructed, this can lead to inaccurate readings. Additionally, consider reverting to an earlier firmware version if the latest update has caused GPS performance issues, as I’ve noticed that some updates can introduce bugs that affect location accuracy. You might also want to check the settings in the Meshtastic app to ensure that the GPS settings are correctly configured and that the trackers are not in a low-power mode that could affect their ability to update their position.
Yes if I might add… the top side is opposite the power connector… keep the top side to the sky… also drive it around in a car… put it on dashboard so it can see the sky as best as possible
Don’t always update to the newest firmware’s
If you do always use Meshtastic web flasher
Make sure to select the exact correct device
Selecting the wrong device firmware or generic device firmware is the best way to buy yourself a brick
If you understand how gps works… it takes almost 30
Minutes for the ephemeral to download… this is 30 minutes of uninterrupted vision to the stars… if this does not happen your accuracy will not be exact
It sounds like your device is working great
I plug into cigarette lighter and place on dashboard in front of windshield and let it sit… just make sure
It can’t fall down the vent hole
This Position issue seems to appear only when I have a node connected to either my iPhone or iPad.
In the map below the Keith Mobile node which is in my truck with an external antenna was connected to my iPhone via Bluetooth and is showing an Incorrect location on the Mesh Map.
The top image is looking at the Mesh Map with the Web Client, the lower image is the Mesh Map viewed on my iPhone. In the lower image you can see the breadcrumbs the SenseCap node left as I was driving around.
The Keith Home node and the other nodes near it were all showing at the correct position location at my residence. At the time none of those nodes were connected to an external device, they were using their internal GPS modules, or they were set to Fixed Location.
If I connect my nodes to an Android device via Bluetooth they show up on the Mesh Map in the correct location. I have set each node to a position precision of exact and a value of 32 using the Python CLI and or the Android app.
I have set the position precision on the Channels to precise for the Primary and all secondary channels.
It appears that only when I have a node connected to an Apple device does the GPS position become skewed. So, I don’t think it is a SenseCAP T1000 E issue but rather an iOS application issue.
I am wondering if anyone else has experienced this odd behavior while using an iOS device attached to their nodes? If this is an iOS issue, I have not been able to find much documentation on it in the various online Meshtastic sites.
Well dang, I still can attach or embed images in my post…
