TS-7180 GPS
From embeddedTS Manuals
The TS-7180 has an optional on-board Telit SL869 GPS receiver. An SMA female connector is provided for the connection of an antenna.
Before it can be used, power to the GPS receiver must be enabled by setting GPIO #19 low, as shown below:
tshwctl -a 19 -r -w 1
| Note: | On REV A/B boards the GPS is always enabled. Boards ordered after March 5th, 2019 will include this modification, but if your unit has Q29 populated and you would like to use GPS, submit an RMA. REV C will include a fix to allow GPS to be powered on/off without modification. |
The GPS receiver may then be accessed via the /dev/ttymxc7 uart.
