Heltec Mesh Node T114

Firmware Version

Description

I have Heltec V3 and T114 v2. With same setting the V3 will update without issue for the route. But the T114 only update once it get the signal and no update at all. BTW, I tried all the versions early than 2.5.15 as well.

Relevant log output

No response

Hi, could you define "won't update" in a bit more detail?

Also, is it possible to provide log files, such as those from the serial console at flasher.meshtastic.org

[aarondong2005]

I am so sorry. I mean the GPS position won't get update from T114 v2. It will only show the position when it get the signal then no update at all.

[fifieldt]

No need to apologize :) Also, thank you for testing the latest firmware, we appreciate your support :)

I have a T114, so I will try to confirm the problem.

To be clear, is this what happens:

1. T114 gets a position the first time
2. Heltec V3, and the app, can see the position of the T114
3. T114 never updates position again
   ?

[aarondong2005]

1. Correct
2. Yes, if I connect to the V3 and able to se T114 v2. But only one position available
3. Yes, it only show one update then no update at all.

How far of a distance did you move between tests?
What app are you using to see the new location packets?

Are you testing the Heltec and T114 right next to each other? If so, the constant transmission of the Heltec (when driving) may be pushing the channel utilization higher, causing the T114 to self limit its position packet interval. when connected to the T114 do you see the Lat/Lon change but just not transmitted and show on another Meshtastic map?

What are your actual position settings for the T114 (update inverval, smart position etc.)?

Edit:
I can do some testing with my T114 today.

Initial testing with firmware 2.5.16 shows i am getting position updates

This might be an app settings problem then. Do you allow the app to always run in the background? Is the bluetooth going to sleep?

What phones and OS versions are your running the tests with?

Post pictures of your position settings, and app permissions.

[aarondong2005]

You should not thinking about app setting related issue. Because I have no issue with Heltec V3. So it is not phone app issue. The issue should be either T114 v4 not upload the newer GPS position. Or the phone app not trying to get the newer GPS position form T114

[b8b8]

ok but we are still trying to narrow it down.
Maybe its just NRF devices having bluetooth issues. today my T1000E was having a GPS issue passing it on to the android app.
What phones and OS versions are you using and do you have any power savings enabled?

The test phone is iPhone 15 Pro Max + iOS 18.2 + Meshtastic 2.5.14 (1327). No Power savings enabled
I Just reset the T114 NodeDB and did fastory reset. Let's see the difference. BTW, I also reinstalled the app as well

i tested with my iPad and it seems to be working for me. Same as you 18.2, though 2.5.14 (1326)

i continued testing all day, and have a position packets consistently throughout. I have ended the test as i have not experienced any issues (even when having the node sitting at home for a few hours with smart position enabled i got a few stationary updates).

Are you using the T114 original L76K GPS module?

[b8b8]

Yes.
