Thought I would add the GPS module for a play see if I can get it to work.
thie below is what I get using the test sketch!
must be something I have done silly!

It looks like the port speed is set incorrectly, causing garbage to be read and then crashing
Did you set it up as per instructions using ublox software?
One more thing
It may take a long time to fix properly (3+ more satellites) when used indoors. The ceramic antenna is not great. A direct line of sight to sky is best, when testing I normally place the gps module + controller on a window ledge inside, can take 10-15m to get a fix, but you need to use ucenter to set it up and get a fix with that software before trying it in the controller.
Oh, and you will need to use a usb-serial adapter to connect the PC direct to the GPS module when running UCenter first. Once its running then you can wire gps module to controller,
OK So the GPS module connects to the U-Center app and after a while I get data and it shows several satalites connected
if I follow the instructions enabling the Uart1 and 2 it enables Uart for all of the items in the pull down lists as required but connecting it to the esp32 running mysqm i get no gps data.
I will try one of the other sketches that use gps
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
"The external antenna is mounted on
the outside of the case. Because the antenna lead is short, you need to ensure there is space to
locate the sensor near where you will position the antenna, so give some careful thought to this.
You can hot-glue the antenna in place, then run the lead through a gap in the case lid to the
main board. Seal the hole for the antenna lead with hot glue."
but is the antenna waterproof?
ty!

Hi Dave

or could the module be faulty? its been in the drawer a while!
blue led flashes
this is the module I used
https://www.aliexpress.com/item/1005006173485270.html
The software for UCENTER is attached
OK So the GPS module connects to the U-Center app and after a while I get data and it shows several satalites connected

gps module connected to the MYSqmPro arduino version works fine!
hi, a minor question about GPS antenna:
in p. 63 Mr Brown says:
"The external antenna is mounted on
the outside of the case. Because the antenna lead is short, you need to ensure there is space to
locate the sensor near where you will position the antenna, so give some careful thought to this.
You can hot-glue the antenna in place, then run the lead through a gap in the case lid to the
main board. Seal the hole for the antenna lead with hot glue."
but is the antenna waterproof?
ty!
