AT Command Name
API Enable. Set/Read the API mode of the
radio.
Interface Data Rate. Set/Read the serial
interface data rate (baud rate) used between
the RF module and host.
GPO2 Configuration. Select/Read the
behavior of the GPO2 line (pin 3).
GPO1 Configuration. Select/Read the
behavior of the GP01 pin (pin 9)
Software Flow Control. Enable/Disable
software flow control (XON/XOFF).
Flow Control Threshold. Set/Read the flow
control threshold. When FT bytes have
accumulated in the DI buffer (UART Receive),
CTS is de-asserted or the XOFF software flow
control character is transmitted.
Parity. Select/Read parity settings.
Packetization Threshold. Set/Read the
character threshold value. RF transmission
begins after receiving RB bytes, or after
receiving at least 1 byte and detecting RO
character times of silence on the UART.
