Check the reed switch on gpio15, it seems that it is constant active. Normal voltage on gpio15 should be 3.3V, only when the reed switch is activated it should be 0 V.

I guess that you use a recent Beitian BE xxx, which has now a default baudrate from 115200 baud. The sw for the T-display only checks the GPS for 9600 bd and 38600 bd....
Do you have a older GPS on hand to test this ? I shall take a look at the sw for adapt to 115200 bd, but it wil take some time...
Greetings, Jan.

yes, first attempt was with an M10, it works with an older M8.


can’t I select the required baudrate to 115200 and skip the auto detection?

I have them enclosed but even selecting auto detect, they jump to 115k when the module initializes, and then "changes" in the config page to 115K. My firmware is 6.01c

Sorry for this very basic question.
Which Beltian GPS module and UBOX chipset version (M8, M9, M10?) are people using now for new builds. And what are you reasons for the choice?
I am sure there is discussion of this in the 52+ pages of this thread but I am not finding it easily.
Thanks for your thoughts. :-)

Many thanks Jan. 😎

Yesterday, I had a low wind session @ my homespot. I tested 4 PMMA-case ESP-GPS with next configurations :
1. Arm mount, BE182 partly covered, sats limited to 18 in the SW (motion setting)
2. Arm mount, BE182 free sight, sats limited to 18 in the SW (motion setting)
3. Boom mount, BE182 partly covered, unlimited sats (avg 26 sats)
4. Boom mount, BE182, partly covered, unlimited sats (avg 26 sats)
If you look at the HDOP numbers, nr 1 was worst. The other 3 were more or less the same. I am not sure why nr 1 was worst, maybe due to partly covered BE182, maybe because the hard limit of 18 sats. The 3 and 4 did perform the same as nr 1, but they received avg 26 sats. As walways, the speeds were higher with the arm mount units.
In my opinion, it does not make a huge difference if the Beitian is partly covered.

Greetings, Jan.

Hi,

The LISA GPS development is finally coming to an end 🔥🔥. A huge amount of work has gone into this project over the past months.

I'm currently assembling a first batch of 100 units to fine-tune the assembly process, validate production, and optimize the workflow before scaling up.
If everything goes as planned, the GPS should be fully available over the coming months.

Cheers,
Nico

Hallo,

im Running the ESP without an SD card. Just the 16MB chip.

Is there maybe an issue with wrong memory calculation?
I had I few sessions without a saved GPS file, only the txt. file.
My guess is, it does not includes the files in the archive section.
Is there an option to completely disable this function?
