Hi there, i am not sure if i am in the correct forum here but i give it a try.
i am currently working on this project: GitHub - pcace/open-rally-computer at dev
adding some features to the original repository. everything works out so far, but i have an issue with the gps on the eps32: the cold start times are extremely bad. it takes around 5 to 10 minutes to get a fix. outside! inside of a room even close to a window i have no chance getting a fix...
Once it does have a fix it is a quite stable connection. (my comparison is to a crappy 15 year old ublox m6n module...)
I am wondering what i could do to make it work better - at least a little bit closer to the advertised 30s or so for a cold start to the first fix.
- the module itself is only covered by a 0.6mm 3d printed sheet of PETG plastic, but is surrounded by some cables and swiches.
- bluetooth is currently disabled to avoid interfearences (which should not be a problem - gps is at ~1300mhz and bluetooth at 2400 i thing)
- wifi is enabled and running a webserver (so there could be interfearences?)
here are 2 pictures of the prototype the red circle is where the gps module is placed.
It is connected just by GND/VCC/VCCB + TX / RX.
the serial connection is perfectly fine, running at the modules default speed 115200.
