About NRF52840 RF testing issue

[Mike Hsieh]

Hi Sir

I am testing nRF52840 product with CMW500 BT5.0 testing script. But the testing is easily stop due to connection broken, especially for RX and long range testing. CMW500 vendor told me it's should be DTM issue. My DTM version is 15.3. Is there any suggestion for this situation ?

Thanks

DTM 15.3 is extensively tested so this is most probably a tester issue: Make sure thy are using DTM over UART only as the nRF52840 doesn't support HCI.
