case about dtm and RF Channel

user83603

Hi,

IC nRF52833

sdk:nRF5_SDK_17.1.0

1. Does BLE have the concept of signaling test mode and non-signaling test mode?

2. Is DTM in signaling mode or non-signaling mode?

3. How do I enter the signaling test mode?

4. How to enter non-signaling test mode in BLE?

5.How to configure the RF frequency range in the program:

In Japan, for example:

In Spain, for example:

In France, for example:

6.Can you turn off part of the RF frequency range, because some part of the frequency range interference is too large

    Hello,

    I assume what you are interested in here is performing radio tests for instance to test radio performance and/or at a test house to measure output power and spurious emissions. In that case I suggest to use the radio test example project:

    https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.1.0/nrf_radio_test_example.html

    In the above radio test example you control the nRF52833 through a UART interface to set it up to different test modes. It is also possible to make fixed test firmware without UART interface as for instance shown here:

    Since you are using the nRF52833 you should open the \examples\peripheral\radio_test\pca10100\blank project. 

    There is also a DTM example project in the nRF5 SDK, however DTM will only run commands specified by BT Sig (described in BluetoothRegistered Core Specification: Version 5.2, Vol. 6, Part F.), for instance to measure electrical parameters are according the BT spec, however DTM commands are typically not used by a test house to test radio regulations.

    Best regards,
    Kenneth
