BT610 - Focused Applications
The BT610 I/O Sensor is orderable alongside several sensor options (cable assemblies sold separately) for popular sensor use cases.
Thermistor Sensors
Connect up to 4x thermistors (temp range -40°C to +125°) per BT610. For remotely monitoring health and status of various environments and electrical equipment such as HVAC units in control huts.

AC Current Sensors
Connect 3x passive AC Current sensors (0-20A, 0-150A or 0-500A RMS) per BT610 into 3-phase AC power circuits. For indirectly monitoring load profile remotely via current sense method where load, torque and current are directly proportional to each other.

What is IP rating
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:
First Digit | Description |
---|---|
0 | No protection |
1 | Ingress of solid object diameter 50 mm is protected |
2 | Ingress of solid object diameter 12.5 mm is protected |
3 | Ingress of solid object diameter 2.5 mm is totally protected |
4 | Ingress of solid object diameter 1.0 mm is totally protected |
5 | Protected against harmful dust |
6 | Totally protected against dust |
2nd Digit | Description |
---|---|
0 | No protection no protection against liquid object No test |
1 | Protection against water drop vertically |
2 | Protection against water drop 15° Tilt from its normal position |
3 | Protection against water spray 60° from the vertical direction |
4 | Protection from water splash from all direction |
5 | Protection from water jets from all direction |
6 | Protection from strong water jets from all direction |
7 | Protection from water dip 1 m depth water for 30 min |
8 | Protection from water sink should be decided between customer and manufacturer |
How to Exit a smartBASIC $autorun$ Application on the IG60-BL654 Gateway
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.
Can I update the firmware of the BL654 module inside my IG60-BL654 Laird Linux gateway?
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.
