nRF Connect Programmer does not recognize hardware

Jim R

Have used nRF Connect V3.30 for the past year to program nRF52DK with USB and nRF52832 BLE modules with Segger J-Link Base programmer without issue.  Updated programmer app yesterday and now the programmer does not recognize the nRF52DK or the Segger programmer.  The devices show up in the Select Menu but give an "Unrecognized device.." message when selected.  Have uninstalled nRF Connect and all Segger programs and drivers and re-installed the latest versions several times but get the same results.  Tried installing old V3.30 nRF Connect but get message that Programmer app is only compatible with nRF Connect V3.60.  It appears that installing the old nRF connect still installs the latest individual apps.  How do I either get V3.61 to work or get the old Programer app?

    Hi Henry

    What kind of device are you using in conjunction with the nRFConnect Programmer, is this seen with a Development Kit or some third party device? Also, what version of J-Link do you have installed? Can you provide the full log as well?

    We are currently looking into this issue and seeing the logs would help a lot. I'll see what I can do in order to provide the older v1.4.7 for you.

    Best regards,

    Simon
