LED Indicators
Module pins
RSSI/ TX LED
and
CONNECTION/ RX LED
are designed to directly drive LEDs. The Red
LED (D1) of the Radiocrafts Demo Board is connected to module pin
RSSI/ TX LED
, and the Yellow LED
(D2) is connected to module pin
CONNECTION/ RX LED
.
We recommend that these LED outputs are also implemented in target hardware. The LED signals will
be useful for system deployment and configuration.
Flash patterns as documented in the data sheet assume the outputs to be sourcing power to the LEDs.
This is the recommended configuration, that will also work for low power, battery operated devices while
in sleep mode.
If using the outputs as power sinks, the LED flash patterns will be inverted, and connected LEDs will
leak power while the module is in sleep mode.
LED Indicator Time-Out
In many applications, the LED indicators will be useful during installation or for field service purposes.
After installation, the indicators may in some applications no longer be desirable. For battery operated
End-Devices the indicators will represent an undesired power consumption.
The configurable
INDICATORS ON
8
parameter determines the time the indicator outputs are active after
a power-up reset. By default, this parameter is set to 255 = permanently ON for Gateway and Router
Devices. For End Devices, the parameter will automatically be set to default value 1 for a one-minute
time-out, when using the 'N' -
SET END DEVICE MODE
configuration command to change between
operational modes.
Setting the
INDICATORS ON
to 0 will permanently disable the indicator function.
Pulse Counter Feedback Indicator
Any GPIO may be configured as a feedback output for the pulse counter mode. Please see
PULSE COUNT
Verification for details on the Pulse Counter Feedback function.
The duration of the pulse counter feedback is also controlled by the
INDICATORS ON
parameter, which
will optionally disable this output after a pre-set time-out.
RSSI Indicator LED
When configured as a Router or End Device, an LED connected to module pin
RSSI/ TX LED
(Radiocrafts Demo Board Red LED, D1), will function as an RSSI indicator for Tinymesh™ Router or
End Device modules. The LED will flash with one of the following frequencies/ intervals, based on RSSI
level for the established connection:
1. Very fast flash (Five flashes per second):
RSSI is better than configured
EXCELLENT RSSI LEVEL
2. Fast flash, (Two flashes per second):
RSSI is good, at least
CONNECTION CHANGE MARGIN
better than
RSSI ACCEPTANCE LEVEL
3. Moderate flash, on for 1 second, off for 1 second:
RSSI is acceptable for reliable communication
4. Very slow (2 seconds ON, 2 seconds off):
RSSI is below the
RSSI ACCEPTANCE LEVEL
that will allow new connection. No new
connections will be established at this low RSSI, but existing connection may still exist if the
Connection LED is still flashing
Connection Indicator LED
When configured as a Router or End Device an LED connected to module pin
CONNECTION/ RX LED
(Radiocrafts Demo Board Yellow LED, D2), will function as a connection indicator. The LED will flash
with one of the following patterns:
