Here are some common AT commands I have most frequently while working on XBee projects. Remember, ALL NUMBER VALUES ARE IN HEX!
- ATID – PAN ID
- ATDH/DL – Destination address high/low: which local address to send ADC data
- ATMY – Local address of this unit
- I/O:
- ATD0…D8 – digital pins I/O enable
- ATP0…P1 – PWM output enable
- ATIU – I/O output enable (UART) – send out through serial
- ATIA – I/O input address – address to pay attention to for serial output
- ATIT – ADC Samples before TX
- ATIR – ADC Sample rate (ms)
- ATBD – Baud Rate:
- 3 = 9600
- 4 = 19200
- 5 = 38400
- 6 = 57600
- 7 = 115200
- ATWR – Write parameter values
Remember to ATWR to save changes to parameters.
Interesting note from the manual: “The maximum sample rate that can be achieved while using one A/D line is 1 sample/ms or 1 KHz (Note that the modem will not be able to keep up with transmission when IR & IT are equal to “1”).”
