RC7620 module AT command interface

From the RPi command line (shell)

AT commands can be set from the Raspberry Pi via

  1. AT commands sent from the Raspberry Pi Physical UART /dev/ttyAMA0 on the 40W header to the PiloT RC7620 physical UART
  2. AT commands sent from the Raspberry Pi Virtual USB UART /dev/ttyUSB2 to the PiloT RC7620 virtual AT command UART

For example (assumes modem physical baud rate has been set to 115200)

sudo minicom -D /dev/ttyAMA0 -b 115200

or

sudo minicom -D /dev/ttyUSB2

IP connectivity

At the time of testing the RC7620 supported two HOST IP connection methods

  1. PPP
  2. RMNET

For information how to use PPP and RC7620 see this

Sierra Wireless currently supply their Mobile Broadband Package (MBPL) for Linux which supports the USB RMNET protocol. The MBPL components and documentation can be downloaded from https://source.sierrawireless.com/

LEDs

The PiloT LEDs are connected to the RC7620 GPIO. The state of the LEDs

LED D6

Configure the RC7620 GPIO 7 as an output which sets the LED on when the PiloT is powered up

AT+WIOCFG=7,4,1,1

Turn the LED D6 ON

AT+WIOW=7,1

LED D5

Configure the RC7620 GPIO 7 as an output which sets the LED off when the PiloT is powered up

AT+WIOCFG=8,4,1,0

Turn the LED D5 ON

AT+WIOW=8,1

RC7620 USB port composition

Default USB composition is

diag,nmea,modem,rmnet0,ecm
