AT$P=uint

Set Power Mode

To conserve power, the AX−SFJK can be put to sleep manually.

Depending on power mode, you will be responsible for waking up the

AX−SFJK again!

0: software reset (settings will be reset to values in flash)

1: sleep (send a break to wake up)

2: deep sleep (toggle GPIO9 or RESET_N pin to wake up;

the AX−SFJK is not running and all settings will be reset!)

AT$WR

Save Config

Write all settings to flash (RX/TX frequencies, registers) so they

survive reset/deep sleep or loss of power.

Use AT$P=0 to reset the AX−SFJK and load settings from flash.

AT:Pn?

Get GPIO Pin

Return the setting of the GPIO Pin n; n can range from 0 to 9.

A character string is returned describing the mode of the pin,

followed by the actual value. If the pin is configured as analog pin,

then the voltage (range 0…1 V) is returned. The mode characters

have the following meaning:

Mode

Description

0

Pin drives low

1

Pin drives high

Z

Pin is high impedance input

U

Pin is input with pull−up

A

Pin is analog input (GPIO pin 0…3 only)

T

Pin is driven by clock or DAC (GPIO pin 0 and 4 only)

The default mode after exiting reset is U on all GPIO pins.

AT:Pn=?
