My backup GPS is an old Android phone
with the ShareGPS app side loaded onto it. This phone
is not rooted nor does it even have a sim card. Instead, every useless App is disabled to limit CPU demand, storage
, heat generation and battery
drain. It is in linked via Bluetooth and sealed in a watertight plastic case.
It trickle charges (.5 amps - enough charge when only using it for GPS) via a DigiYes® Ultra Slim Compatible Wireless Charging
Receiver and a Turbot Wireless Charger
, 3-Coils Qi Wireless Charging
Stand. Or you can just buy an extra long USB charging cable, a ziplock bag and a little dab of epoxy
to get the 1.5 amp charge.
Long story short, (I know, too late...) you can hack an old cellphone (or 2, 3, 4 or 5) to deliver NMEA
compliant, GPS sentences to your laptop
, tablet or whatever via WiFi
or Bluetooth. This makes a great backup to your onboard GPS and can also be used to test your system
Btw, with a long cord, you can place the phone anywhere within range of your laptops' Bluetooth or Wifi
Hope this helps...

Any suggestion as how to fix this issue?
