Is it possible to upload a SoftDevice over BT onto a fresh, brand new chip, or must one first flash a specific OTA-compatible FW onto the device via UART/JTAG with a SWD programmer? I haven't found this stated anywhere explicitly.
If not, is there a plain list of requisite steps like this that must be done in order?
If so, which tools would do this - nRFgo, MCP, or nRF Tools?
I tried flashing the s140 stack with nRF Tools, but got the error "DFU Service Not Found", which would make sense if I first need to install a compatible FW over wire to enable OTA.
Thanks!
