Bluetooth Dtm Protocol; Example; Regulatory Testing Commands - Digi XBee 3 Cellular LTE-M User Manual

Regulatory firmware
Bluetooth DTM protocol
The Bluetooth DTM protocol is implemented as specified in
specification.
All commands are two bytes long (16-bits) and receive a response, which is also two bytes long. All
multi-byte sequences are big endian.
The protocol has also been extended with the two commands shown in the table below to allow
changing the transmit power and to override the packet type to use an unmodulated carrier.
Description
Set the transmit power.
The response is the actual
transmit power that is set,
which may be less than the
requested if the radio does
not support the requested
transmit power.
Override the packet type.
This will supersede the packet
type specified in the
transmitter/receiver test
commands.

Example

Example of a typical test sequence.
Description
Set transmit power to 10 dBm
Set PHY to LE 1M
Override the packet type
Start TX test at 2402 MHz
End Test

Regulatory testing commands

The regulatory commands are used for regulatory compliance testing of your Bluetooth and cellular
radio components. The commands work in conjunction with regulatory firmware which you must
install onto your XBee before you use these commands.
Use the commands
Before you can use these commands for regulatory compliance testing, you must do the following:
