I am working on interfacing the Lassen iQ to an SX-48 microcontroller. While I have successfully been able to receive and log TAIP information from the Lassen iQ, I would like to understand some odd behavior I noticed.
I have my Lassen iQ (GPS) in my office and experiment with it there. I usually do not receive information from satellites inside however it does deliver information over both ports which is great for evaluation and development. After about 10 minutes, it stops delivering the TAIP information to my microcontroller. I can cycle the power and it will start again only to stop after a bit. The documentation indicates that the GPS may stop under certain conditions so I thought the direct connection from the TX line on the GPS to a microcontroller high impedance input might cause an issue.
Anyone else have an idea why it stops?
Thanks,
Joe
