BLE DTM Test (nRF52840) — Direct Test Mode V1.1.7 Plugin Fails to Open After Installation

[Frank Cai]

Bluetooth physical layer Direct Test Mode testing is used to verify BLE low-level RF transceiver performance. The required software is nRF Connect for Desktop V3.7 + Direct Test Mode V1.1.7 plugin. The PC is unable to properly install the DTM V1.1.7 plugin, and the latest version of Direct Test Mode cannot be used for testing either.

Hello,

Why do you seemingly use very old nRF Connect for Desktop and DTM app?

I think the latest is v5.3.1 and v3.1.2 for those two apps.

Hello Kenneth,

Because the previous development was done using nRF Connect for Desktop V3.7 + Direct Test Mode V1.1.7 plugin.

However, recently we found that it no longer works. Also, when using the latest version of the app, Direct Test Mode cannot obtain any data.

Is it because the latest version of the app does not support the nRF52840?
