Re: bluefruit le friend sniffer firmware version

Typical of forums we have to answer our own questions. After adding an SWD connector to my Bluefruit LE Friend Sniffer V2 Firmware device, I was able to flash the latest Nordic Sniffer V3 firmware "sniffer_pca10028_129d2b3.hex" to the device and it seems to work well with the minor exception that the blue led no longer lights. Even after re-flashing the V2 beta firmware "sniffer_pca10028_51296aa.hex" file, which is supposed to be the pre-loaded version, the blue led still didn't work. To perform the flashing I used the Nordic "nRF Connect for Desktop", Programmer module, and my Segger JLink EDU mini programmer hardware. Upon opening the Programmer module the JLink EDU mini showed up as a selectable device and the Add HEX File option allowed browsing to the location of the new firmware. Then it was as easy as selecting "Erase & write".
With the V3 firmware installed the device appears to work seamlessly with Wireshark 3.2.4 and Python 3.8. Previously with V2 firmware I experienced some Wireshark crashes when starting, stopping and refreshing the sniffer capture.
Eventually I'll try flashing some non-sniffer firmware to the device to see if the blue led is dead (I'm sure, however, that it was lit just prior to flashing so I don't think it was damaged due to soldering).
