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.

A forum search suggests the downloaded code contains

Nordic Semiconductor\nRF51822 Beacon v1.1.0\Precompiled hex\

with the hex file in it.

Thanks for the quick response. I did originally try this, along with loading the v7.1.0 S110 supplied in the SoftDevice folder in the same location as the Precompiled hex folder. The app does not run correctly on my beacon, and it may be because all my beacons are variant nRF51822-CEAA (even those recently ordered) while that firmware may be built for the more recent nRF51822-CFAC variant. That' why I was looking for the original copy of the app that was installed on my beacon. Just for fun, I did try installing that app you pointed me to with all the variants of S110 that I have which include v7.1.0, v6.2.1 and v5.2.1, none of which worked.

Hi.

You can find older versions of the Beacon firmware here. Beacon version 1.0.x uses S110 v6.0.0 and SDK v5.1.0 (documented here).

There is a trick for finding older releases of our firmware and that is to click on the version number instead of the code:

It works for most of our software, SoftDevices, SDKs, etc.

What build code do you have on your new and old chip variants? And when did you by your latest version? There is a CEAA version of all three silicon revisions so it is letter number 5 and 6 that will tell us what SDK and SoftDevice are to be used with your particular IC. Have a look at the Compatibility Matrix to learn more.

I was able to find and download the earlier versions of beacon firmware (v1.0.0 and v1.0.1) and thanks to the above tip, was able to find and download a hex file for S110 v6.0.0 (but not 5.1.x). I did take a look at the Compatibility Matrix - it looks like I have beacons with IC Rev 2 chip. In answer to your question, the full chip variant that I see is CEAAD00. When I run nRFgo Studio to program firmware, I see displayed "nFR51822" followed by "CEAAD00 (0x004d)". and, we bought our latest two beacons during February, 2015. On the plastic envelopes that these latest beacons came in is a tag that reads "nRF6930, Rev 1.0.0, 2014.49" Hope that answers all your questions, and thanks again.

Thanks a lot. So your are up and running now? I didn't manage to find 5.1.x either.
