wayne roberts / Mbed OS lr1110_wifi_geolocation_gateway

simple example of scanning wifi AP and sending to geolocation resolver on cloud

Dependencies:   mbed-http lr1110 sx12xx_hal

test Wifi geolocation with resolving using HTTP POST.

Use with mbed board with internet access and arduino form factor.
With HTTPS, the RAM requirement is minimum 128Kbytes.

and, use with radio shield for europe
or radio shield for USA
which is programmed with trx firmware from updater tool.

This project presents to user mbed STDIO serial port at 115200bps, which lets you perform wifi access point scan on LR1110 and send the resulting access point list to a geolocation provider on the cloud.

Use the project by itself to run wifi scan on the serial terminal (at 115200bps), or use with lr1110_wifi_geolocation_device to receive wifi list from remote device (over LoRa) to resolve location of that device using gelocation provider on cloud.

On serial terminal, use ? question mark to see list of commands. ws to run wifi scan, or ws p to wifi scan and resolve location with cloud provider via HTTP POST.

project setup

Edit main.h to uncomment which geolocation provider you wish to use, and get API key from them:

• google geolocation
• combain geolocation
• TODO others?
  (choose one) Put your API key for geolocation provider into the URL in geolocation source file (such as google_geolocation.cpp or combain.cpp)
