AT$P=uint

Set Power Mode

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

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

AX−SFEU 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−SFEU 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−SFEU 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, fol-

lowed 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=?

Get GPIO Pin Range
