This code searches for an I2C or serial connected GNSS module based on u-blox MAX-7Q (RAK1910) or u-blox ZOE-M8Q (RAK12500).
Then it starts a location acquisition in the time interval set with ATC+SENDINT. It will try to get a location in 1/2 the time of the acquisition time.
If a location was aquired, it will send the location in Cayenne LPP format over LoRaWAN or LoRa P2P. If no location was found, it will send only the battery voltage.
This library is tested with u-blox MAX-7Q (RAK1910) and u-blox ZOE-M8Q (RAK12500).
It uses Sparkfun libraries over I2C (RAK12500) or Serial (RAK1910) and UBX messages, which are shorter than NMEA messages and reduce the communication effort.
For the u-blox MAX-7Q (RAK1910) an adapted version of the Sparkfun library is used.
Depending on the satellites seen by the GNSS antenna, it can take up to 30 seconds to get a location. The send interval set with ATC+SENDINT should not be shorter than 1 minute.
Due to the code size this example will only compile on the RAK3172 with one LoRaWAN region enabled. Otherwise it will throw an memory overflow error during compilation.
