original nRF51822 beacon firmware backup

[EdCubic]

Gentlemen: Do you have posted a copy of the original firmware that comes installed on the nRF51822 beacon? I have been experimenting writing my own app on that beacon, and so replaced that firmware with my own. But now, I need to put this aside for a while and would like to re-install the original app and bootloader (I presume I can used the S110 v6.2.1 with this). Thanks.

Yes, so far as the beacon app is concerned. If I just load the appropriate S110 hex file and firmware app, it will run on my beacons. In fact, I've been able to make all 3 versions of the app run - including the latest one indicated in your first response above. It turns out that the bootloader hex has been the problem all along. If you load that on, it seems to damage the image of the beaconware app in memory, and the beacon is always in bootloader mode. It will not respond to presses of SW1 or SW2, nor to a power recycle. I have tried this on several of my beacons. There could be a problem with my beacon version and the bootloaders that I have access to.

Maybe this thread can help you on your way?

I will take a closer look at that thread. FYI I am using the Nordic DK (the PCA 100028 board) and a Tag Connect cable connection to program my beacons. But for now, the beacons are running well enough for my experimentation. If I have further questions, I'll be contacting you again. Once again, thank you much for your time; your suggestions were very helpful.
