WifiTimezone class - Requests the imp to scan for wifi networks, sends that data to Mozilla to geolocate the imp, sends that data to timezonedb to collect timezone data.

Hexdump is a function to output binary data in a hex + text format on a serial port.

Hexdump

This function will dump a blob or string as a hexdump to a serial port.

The input looks like this:

hexdump("RECV", "Hello world\n", "uart57");

The output (with a more complex input!) will look like this:

Squirrel port of the BlueGiga BLE112 BGLib using BGAPI running on an Electric Imp device.

BGLib for Squirrel

This implements the BGLib library for Bluegiga's BLE112 Bluetooth Smart module.

It assumes you have connected from the Imp to the BLE112:

  • UART (uart1289 is recommended as flow control is important)
  • Wake pin (optional depending on BLE112 configuration)
  • Reset pin (optional but really helpful as software reset is not always reliable)

The device pings the agent every second. If it misses a pong response it turns on the light for at least 10 seconds.
device.on("ping", function(ping) {
device.send("pong", ping);
})
server.log("Agent started")
