Sentrius IG60-BL654 and IG60-BL654-LTE Wireless IoT Gateway

IP stands for Ingress Protection. Its a standard we use to check the sealability of a product once it is installed.

It is composed as IP## , where first digit is for dust/solid objects and the 2nd digit, is for liquids.
Here is the meaning for each numerical code:

With access to the IG60 Laird Linux console you can start the terminal program "microcom" to issue AT commands to the integrated BL654 BLE module.
The BLE modulel istens on /dev/ttyS2.

# microcom /dev/ttyS2

To exit microcom use ctrl-x.
 

There is a python script on the IG60-BLE654 LL developers SD card image called

btpa_utility.py

This can be used to upload, rename and delete sB apps to and from the IG60-BL654.

It can also be used to list the directory content and sending AT commands to the BL654.

Once you have created the soft AP on your Linux system and have successfully connected clients to the soft AP you can issue the command

# iw wlan0 station dump

to get a list of connected clients.

Note: the interface name (here: wlan0) might be different in your system.

There exist pre-defined GPIOs in the IG60 to control the BL654 module, which can be found under /sys/devices/platform/gpio:

• bt_nautorun: If set to 0 (low) autorun is active and and $autorun$ application will start after power up/reset and if set to 1 (high) autorun will be disabled.
• card_nreset: Setting to 0 (low) asserts BL654 reset and 1 (high) releases reset.

To exit an $autorun$ application nAUTORUN needs to be set high followed by a module reset.

echo 1 > /sys/devices/platform/gpio/bt_nautorun/value (disables autorun)
echo 0 > /sys/devices/platform/gpio/card_nreset/value (assert reset)
echo 1 > /sys/devices/platform/gpio/card_nreset/value (release reset)
echo 0 > /sys/devices/platform/gpio/bt_nautorun/value (re-enable autorun)

You should now be able to connect to the BL654 through e.g. microcom with access to the smartBASIC interactive mode:

microcom -s 115200 /dev/ttyS2

You can now use e.g. AT&F* to clear the flash file system before loading a new smartBASIC app to the module with the above Python script. (Note: CTRL-x will exit microcom).

Note: You can always check the current state of the above GPIOs with

cat /sys/devices/platform/gpio/.../value

See also the IG60-BL654 online documentation.

Yes, there is one pin (4) on the power supply connector that can either be configured as an input or as an output.

You can follow Lairds application note "Configuring external I/O pin of the IG60 Laird Linux variant as input or output".

You can use the Network Manager command line interface to create an open hotspot using this command:

nmcli con add con-name open_hotspot ifname wlan0 type wifi ssid yourSSID mode ap wifi.band bg wifi.channel 6 ipv4.method shared

 

Yes. There is a python script on the IG60-BL654 LL developer SD card image called
btpa_firmware_loader.py

This can be used to upload a new firmware to the BL654 inside IG60-BL654 LL.

You need to boot into Linux and after Login log in issue the command

fw_setenv ethaddr <desired MAC address> 

for example:

fw_setenv ethaddr AABBCCDDEEFF

and reboot

You can read out the address previously set with:

fw_printenv ethaddr

On the LairdLinux versions of the IG60 (455-00006, 455-00076, 455-00084 or 455-00088) you can access the console port by either attaching a USB to Serial adapter to the IG60 USB port and a null modem cable to your computer or by attaching a USB to serial cable to the IG60 USB port and a null modem adapter to your computer.

Also on the IG60-Serial (455-00006) or the IG60-Serial+LTE (455-00084), you can connect a null modem cable to the serial port on the IG60 and your computer.  

Note: You are not able to access the console on a GreenGrass version of the IG60 (455-00008, 455-00081, 455-00085 or 455-00089).
