They are all V2.0 chip and should work fine with the sniffer firmware. I have no further solution for now. If you want you can send us one of your board here and we can test and find a fix.

Devices we have tried are: PCA10001 V2.2.0 G0 chip PCA10001 V2.0.0 C0 chip PCA10000 V2.2.0 G0 chip 2 pieces PCA10000 V1.0 CA chip All work with Master Control Panel We have seen various difficulties with these devices on different PCs with MCP, unplugging the device and reconnecting seems to resolve the MCP problems.

@Gus Gustafson: this is pretty strange. If it was the issue on the firmware of the dongle, reflash (erase all+ program) it should make it fresh and run again. We actually haven't experienced this before. Could you read the laser marking on top of the chip on your kits ?

One more note. Just discovered that if I program the PCA10000 with the MCP firmware then put it back to the sniffer firmware it runs until the next time it is disconnected.

OK, have tried several Jlink drivers, no help, Clearing the comm port with F, no help, Different USB port, no help, and un-installing all the different PCA10000 and PCA10001s that I have tried. None work.
I had one last PCA10000 that had never been connected, tried it this morning. Worked after programming. Used nRFgo Studio to program it. Logged out of Windows, logged back in, still working. Now unplug the dongle and plug back in. Device manages shows comm port exists, but Sniffer does not find the device. nRFgo studio verifies that the hex image is still correct. Serial port sniffing software shows that Sniffer.exe is writing to that comm port but nothing is coming back from the device.

I will report this to the sniffer developer to see if he has a solution.

I guess you may already tried the following, but just in case:

Could you tried to

Update to latest Jlink driver
Press F in the console to clear out the COM port.
Connect the dongle to different USB port.
Uninstall the COM port in Device Manager and install it again.
Try to manually modify the COM port to another number in device manager.

Been there, done that. Have tried several PCA10000 and PCA10001, several different revisions. All work only one time and then after a reboot nothing.

Hi Gus,

You may need to unplug and plug the dongle back when the console's looking for the COMPort. I usually have to do that.

If that doesn't work you can try to reprogram the dongle again by pressing Ctrl+R.

Please let me know if the issue remain.
