I would like to use the nRF52840 as the subject device in a EE Capstone design course. Compiler tools (both Keil and Segger) work well and will be easy to teach but I am unable to use the nrfconnect-2.4.0 under Windows due to 'BDS/Androm.hrhsn' which is detected and quarantined by Avira, hence DFU programming from the PC does not appear to be possible. How soon will a clean version of nrfconnect be available on your website?
