I have no clue why this happens. Does no one use the TF-sensor for such "long" time without restart?

New findings:
The TF-sensor readings "hangs" exactly after 13 days.
After that always the same value is given out.
This behavior was occured every 13 days in the last 5 months.
Very strange.
What could that be?

Hi folks

I have a program that reads the TF sensor every second.
After 1 or 2 weeks, the sensor suddenly only delivers the same constant value (last value read from it).
I have to restart the whole device and then the sensor does read out correct current values again for 1 or 2 weeks.

example (values only to visualize with some fault measurement like in real):
99.7, 99.6, 99.7, 98.9, 98.8, 98.5, 98.3, 98.4, 98.3, 97.9, 97.6, 97.2, 97.3, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7

Does anyone know the problem?

It works with Firmware V1.5.1 and above

@m5stack said in GPS Unit (AT6558):

start takes time, (maybe 3~5min). the signal quality very important , so had better use it in the house outside.

Thank you very much.
Unfortunately it does not work with any port as I have described above.
I just receive Quality "NO signal". It can stay for hours outside, nothing changes.
Cold start time is 35 seconds as you can see in technical details of m5stack.

BUT HERE IS THE BEST:
I received today 4 new GPS Units and now it works.
My "old" two GPS units are not working.
That was it. A lot of waited time

@M5StickFreakler

Start the Desktop IDE Version (Offline Version) of UIFlow, then go to "CheckUpdate" there you start the update to the new version 1.0.9.1 then Pb.HUB and Pa.HUB are activated again and you can access them !
You may have to install the software completely again !?

greetings skink

Hi skink

This was my mistake.
I have already the newest version of UI-Flow installed but I didn't realized, that I have to change the Version via the following button too:

So I have switched to V1.5.1 and now the pa.Hub and Pb.Hub aren't grayed out.
Too dumb of me.

Thank you and best regards

@world101 said in GPS Unit (AT6558):

Hint: if you use the forum search feature you can find threads like this that say the M5Stack Fire PSRAM conflicts with port C because they use the same GPIO 16 and 17, which is also the same ports the GPS units and modules use (see the GPS docs). The work around involves cutting a trace and rewiring.

Thank you
But I would like to get a solution from M5Stack withouth cutting wires in all my devices.
M5Stack sell this GPS units to use 'em on M5Stack devices and does not provide any information that we have to modify the hardware to get running it.
Also I do not use the GPS Modul, but I use the GPS Unit!

@m5stack could you provide customers with any official information about the behavior?

Best regards
Thomas

@m5stack said in Pb.Hub and Pa.Hub grayed out?:

@m5stickfreakler you could select the 1.5.1 (beta) version in the navigation. then will solve this problem

Hi
I have installed Firmware 1.5.1 on my M5Stack Fire devices.
The problem ist not the firmware, but the Desktop UIFlow Version 1.0.9.1.
That has nothing to do with the firmware Version of the device.
Or do I something missunderstand?

Best regards
Thomas

Hi folks

With newest UIFlow Desktop Software V 1.0.9.1 the Units Pb.Hub and Pa.Hub are grayed out.

I have buyed it some weeks ago and now it is not supported anymore?

Why????

Do I something wrong?

Best regards
Thomas

@ajb2k3 said in GPS Unit (AT6558):

@M5StickFreakler what firmware are you running on your devices?
I am checking through items at the moment and finding problems due to the switch to the mainstream micropython branch.

Hi ajb2k3

I have checked it with UIFLOW 1.0.9.1 and following firmwares

• 1.2.3 --> not supported
• 1.3.2 --> NOK
• 1.4.4 --> NOK
• 1.4.5 --> NOK
• 1.4.5.1 --> NOK
• 1.5.0 --> NOK
• 1.5.1 --> NOK

Nothing is working. I have tested it on 3 different M5Stack FIRE with 3 different GPS units.
Each on all ports - nada

It is very frustrating and time consumpting and costly. I think M5Stack should increase its quality standards. Here in Switzerland, we are used to the fact that products work what they promise and what we pay for.

Best wished
Thomas
