BLE 05: Configuring a scan

This example shows how to configure scan parameters and makin a scan with them, printing number of discovered devices and scan results stored in EEPROM.

Required Materials

1 x Waspmote 1 x Battery 1 x Bluetooth Low Energy module 1 x Bluetooth module antenna 1 x Expansion board (if socket 1 is used) 1 x SD card

Notes

- Socket 0 is used by default - EEPROM is used in this example by default. - Never unplug module while Waspmote is turned ON. - Bluetooth module antenna should be connected. - The battery must be connected in ANY example. - This example can be executed in Waspmote v12 and Waspmote v15
