Hello.
First of all, thank you for the excellent tutorials, especially the use of ESP NOW.
Regarding the use of GPS, both with the NEO-M8n and the NEO-6M, I would like to know how to change the data acquisition speed.
I have reviewed the information available online, and also with little success from UBLOX. It should be noted that I work with Apple for this last one, and UBLOX does not offer any guidance in this case.
The model is a NEO-6M at 1 Hz, and I would like to change to 2 Hz or 3 Hz, although I believe the procedure will be common.
I use the “Arduino ID.”
I would appreciate help on this issue, or to know where I can find it.
Thank you very much from Barcelona.

One big problem with these “u-blox” modules is that too many sellers are offering counterfeit products. I had one of those (very much like the one in the photo) and it turned out to be a counterfeit one. Just google for “counterfeit u-blox gps modules” to get more info. The modules may work to a point but their GPS reception may be worse and they may have a different/older firmware, for instance.

Here is one link (if they are accepted here):

I made a similar one, but with Micro python, writing directly on Esp32 flash. Now I can improve it with your .KML template.

Thank you!

Hi.
That’s a very interesting project and quite complicated.
I’m not sure if that’s possible to do with this kind of display and with the ESP32.
Maybe there are lightweight libraries to draw a map, but I’m not familiar with it at the moment.
Regards
Sara

Hi.
Has long as the antenna as an ipex connector (to uFL) or ipex adapter to UFL to connect to the board, you don’t need to solder.
Make sure it works in the range of 3 to 5V.
You can get a ufl to ipx connector separately if needed.
You can search on an online store for “external antenna gps ipex”
Regards,
Sara

Hi Sara,
very interesting I’ll try it.
But it will possible in a future project to show directly in a ESP32 CYD or a ILI9341 display Google Maps?
I.e precharging a limited zone of Google Maps in the Sd card.
Bye Renzo
