Hi Abhijith,

I resolved this by add timer3 in prj.conf

Thanks for the effort.

Jeeva.

Hello,

I tested this sample here now for nRF52840dk, and it is working fine on my side. Have you changed anything inside the sample? Please share the whole log by using the insert tab.

Delete the generated build folder and try to build it again.

Kind Regards,

Hi Abhjith,

I am trying to compile DTM code for nrf 52840 from NRF example(samples/bluetooth/direct_test_mode).

My build config:

board: nrf52840dk_nrf52840

Path: boards/arm/nrf52840dk_nrf52840

prj.conf is

# Configure assertions

CONFIG_ASSERT=y

CONFIG_ASSERT_NO_COND_INFO=y

CONFIG_ASSERT_NO_MSG_INFO=y

CONFIG_HW_STACK_PROTECTION=y

CONFIG_CONSOLE=n

CONFIG_UART_CONSOLE=n

CONFIG_LOG=y

CONFIG_LOG_PRINTK=y

CONFIG_USE_SEGGER_RTT=y

CONFIG_LOG_BACKEND_RTT=y

# Use necessary peripherals

CONFIG_NRFX_TIMER0=y

CONFIG_NRFX_TIMER1=y

CONFIG_NRFX_TIMER2=y

CONFIG_FEM_AL_LIB=y

But i am receiving the following compilation (attached as file).But able to compile for 52832 sucessfully.

Can you shed some light on this.

Hello,

You can find more details inside the Bluetooth:direct test mode section. See the section on testing.

Hi Abhijith,
Sadanam undu.

Can you point me to the latest DTM code base and the command set ? Any link will would be helpful.

Hello,

When the Direct Test Mode app is taken, it always validates the firmware, and it's prompting you to programme the available firmware inside the DTM application. But you can always opt out by clicking the NO button to test your updated or custom firmware.

I recommend reading the blog post, which will give you an idea of testing.

Hi Abhijith,

Thanks for your response.

what i am looking for, is to compile and build the compatible DTM code that supports DTM-desktop app ,reprograms.

(ie, DTM- desktop app will find my custom- DTM firmware compatible and it will not ask to reprogram).

I assumed the DTM code from NRF examples and the DTM-desktop app reprogramming is same.But it obvious they are different as the DTM-desktop asks for reprogramming.

My aim is to modify the DTM code and flash into the device and test it with

1.DTM-desktop app and

2.Via any uart terminal(sending hex code commands)

so that i can test my custom DTM firmware with the DTM-desktop app.

Can you shed some light on this?

Regards,

Jeeva.

Hello,

The nRF Connect for Desktop app communicates with the device using the Direct Test Mode (DTM) commands. The DTM commands are sent via a serial connection, which could be a UART or a USB connection. The app does not directly use Jlink for sending DTM commands. However, Jlink is used for programming the device, which is a separate process from sending DTM commands. See this blog post.

[quote user=""]Eventhough i flashed the DTM firmware , still the NRF desktop app is asking to reprogram?[/quote]

Yes, the application always prompts you to programme the device. I think the application is designed in such a way to make sure the correct version of the firmware is installed.

Abhijith
