To calibrate the temperature sensor, locate the Tinymesh

module in a temperature controlled

environment, enter

CONFIGURATION MODE

and make sure the module is given sufficient time to adapt

to the environmental temperature.
Read back the current value of the temperature sensor using the

GET TEMPERATURE

command.

Calculate the actual temperature using the formula in

TEMPERATURE READING (U- COMMAND),

and

find the offset as the difference between actual room temperature and the sensor reading.
Multiply the found difference by 4 and subtract from the

TEMP OFFSET

, if the sensor is showing too high

value, or add to the

TEMP OFFSET

if the sensor is showing too low temperature.

Verify the sensor calibration by repeat readings using the 'U' command

Example:

To calculate a new temperature offset
Room temperature:

24 [°C]

Module reading (U- command):

0x9A = decimal 154

1) Convert module reading to temperature in °C:

154-128 = 26 [°C]

2) Calculate the temperature error reading:

24 – 26= -2 [°C]

3) Calculate the compensation offset:

-2 * 4 = -8

4) Calculate the new Temp Offset value:

Temp Offset= TempOffset -8

TEMP OFFSET

is currently set at the factory default 128, the new

TEMP OFFSET

will be 120

The Tinymesh

protocol runs through a full Power On Reset Cycle,

to ensure all configuration changes are applied.

Setting and Changing the Network ID (NID)

The Tinymesh™

NETWORK ID

is an additional level of network addressing that may be deployed to

distinguish between multiple Tinymesh™ networks sharing a common platform or server, such as the
Tinymesh™ Cloud service.

The

NETWORK ID

needs only be entered in the Gateway Device(s), and has no effect on the internal

addressing in the individual Tinymesh™ networks. By entering unique

NETWORK ID

s in the Gateway

Devices, different local networks having identical

SYSTEM_ID

, may still be differentiated on a larger

platform, as the

NETWORK ID

will serve as an additional level of systems identification that provides

differentiation between messages originating from different systems with identical

SYSTEM_ID

The

NETWORK ID

is stored in the Calibration part of Flash memory. This part of flash is retained even

after a

RESET MEMORY

command, and may only be changed using

WRITE CALIBRATION MEMORY

command from Configuration Mode. The

LIST CALIBRATION MEMORY

command may be used to read

back and verify the contents the

CALIBRATION MEMORY

. The following steps should be used to program

a new

NETWORK ID

with value 4 3 2 1.
