Extending Adafruit_BLE Arduino Library

[tomegan]

Sometimes it is helpful to grab the string(char *) output of an AT command from the BlufruitLE (or other board supported by the Adafruit_BLE library). The library at least version 1.9.5 has support for commands that result in success/failure or an integer but not a string. I personally had a need for the Bluefruit's hardware address which is returned by "AT+BLEGETADDR". My solution was to subclass Adafruit_BluefruitLE_UART which otherwise worked for me and is derived from Adafruit_BLE. My subclass is attached. Usage:

Change:

Code: Select all

Adafruit_BluefruitLE_UART ble(BLUEFRUIT_HWSERIAL_NAME, -1);

to:

Code: Select all

BB_Bluetooth ble(BLUEFRUIT_HWSERIAL_NAME, -1);

Add:

Code: Select all

#define DEVICE_ID_LEN	18

at the top of your code.

Then in your setup or loop code you can use:

Code: Select all

char ble_device_id[DEVICE_ID_LEN];
ble.sendCommandWithStringReply(F("AT+BLEGETADDR"), ble_device_id, 18);

and after the code runs, ble_device_id will contain the Bluefruit's hardware address
