NEO-M9N-00B-00 on FlySight2

This is FlySight - device used by skydivers to record flights performance based on GPS data. Skydiving involves airplanes which are a gigantic metal can that dampens the signal, unless the device is held close to the window.

There are similar devices on the market and they have better GPS signal in the very same environment - as manufacturer explained those devices have newer u-blox module and fine-tuned antenna.

Question: does anybody have positive experience with connecting external antennas to N9M and thus improving signal quality? I happen to have few of them from Neo 7M modules

If it does, the follow-up question: from technical specs one of those lower right pins is Antenna pin, but I don't know if I should solder directly to that pin or there should be placed some circuitry in-between.

Hi everyone,

I’m currently working with a GNSS module and trying to figure out how to access some basic device information.

Could someone tell me how I can check the serial number and firmware version of the module?

I’ve looked through the documentation but I’m still not 100% sure where this information is usually accessed — is it done through a specific command, software tool, or interface?

Any guidance or examples would be really appreciated.

Thanks in advance!
