We are using the MT8852B and I can't say that I have had any problems with this, other than the occasional bug all these testers seems to have. What error does the Anritsu give you?

Hi Ketiljo

I'm using DTM 15.3 to test nRF52840 RF performance by testing equipments. I have three type of equipments : MT8852B/CMW500/IQexl, all of these equipment can not smoothly complete their BT5.0 testing script. Seems the connection between DUT and equipment easily broken during test, especially for RX and long range testing items. And we test 52840 DK also have this kind of situation. Equipments vendor mentioned never this kind of issue for other BT5 chip. Do you have suggestion for this issue ?

Thanks

DTM itself hasn't changed. But DTM for Bletooth 5 will have support for coded phy (long range) as well as the normal command set. See the Bluetooth core spec for the details
