Hardware
The following commands allow you to interact with the low level HW on the Bluefruit LE module, such as reading or toggling the GPIO pins,
performing an ADC conversion ,etc.:
AT+BAUDRATE
Changes the baud rate used by the HW UART peripheral on the nRF51822.
Codebase Revision: 0.7.0
Parameters: Baud rate, which must be one of the following values:
1200
2400
4800
9600
14400
19200
28800
38400
57600
76800
115200
230400
250000
460800
921600
1000000
Output: The current baud rate
# Set the baud rate to 115200
AT+BAUDRATE=115200
OK
# Check the current baud rate
AT+BAUDRATE
115200
OK
AT+HWADC
Performs an ADC conversion on the specified ADC pin
Codebase Revision: 0.3.0
Parameters: The ADC channel (0..7)
Output: The results of the ADC conversion
AT+HWADC=0
178
OK
AT+HWGETDIETEMP
Gets the temperature in degree celcius of the BLE module's die. This can be used for debug purposes (higher die temperature generally means
higher current consumption), but does not corresponds to ambient temperature and can nto be used as a replacement for a normal temperature
sensor.
Codebase Revision: 0.3.0
Parameters: None
Output: The die temperature in degrees celcius
