OTA DFU of the precompiled hex to the nRF51822 Bluetooth Smart Beacon Kit

Thanks.

Zipping the precompiled wit he snippet you sent and DFU'ing it helped and the beacon is transmitting again.

However, using the same snippet I can't seem to run my own compiled HEX on the beacons. As far as I was able to under I need to compile a pca20006 s100 makefile for compatibility.

In SDK10 I found

sdk10/examples/ble_peripheral/experimental_ble_app_eddystone/pca20006/s110/armgcc

But compiling it and DFU'ing it to the beacon the bacon will not advertise anything again.

Trying to use the customized SDK for this product compiling is too hard, the Makefiles ha wrong directory depth in them and I wasn't able to get it to compile.

( nRF51822 Beacon v1.1.1/Source Code/nrf51_beacon/ble_app_beacon/pca20006/s110/armgcc )

But I'm not sure there is any point in trying if I can't seem to find another "pca20006/s110/armgcc" example that works

So you are able to do the DFU, but after the DFU, the device does not start to advertise ? Is that correct?

Could you try to create the DFU package like this?

Snippet:

nrfutil dfu genpkg .zip --application .hex --application-version 0xFFFFFFFF --dev-revision 0xFFFF --dev-type 0xFFFF --sd-req 0xFFFE

I'm using the discontinued reference kit: nRD51822 BLUETOOTH Smart Beacon Kit

I don't know which of device it comes with but judging from download it's s110

I guess I will first retry the pre-compiled HEX in the package (It flashed fine but I didn't check if it's advertising) and see

I don't really want to solder the lines even if I find them (it's a really small board)

So I guess I'm a little stuck for now

NRF51822 is the same chip, just without the ANT+ license. Not relevant for BTLE applications.

Those are for different softdevices.

You need to know exactly which softdevice is in the flash, otherwise any application (using BT LE) won't work. Warning: This includes the OTA bootloader.

Personally, I recommend soldering those SWD lines (SWDIO, SWDCLK) and using a J-Link debugger for programming and debugging. This also allows a fresh start with any softdevice version (just do a chip erase).

OK, After a long weekend trying to figure this out I gave up and I hope someone can help me.

I will explain some of the things I tried but in all honesty, I think it will great if someone can do me a huge favor just send me a zip/hex file of that updated this product to advertise my 31 bytes (Contact me and I will send them with a huge thanks and a beer/coffee gift)

Every complied example I tried didn't advertise anything. I tried examples from the product's specific SDK , from SDK 10, SDK 12.3... I tried changing the linker script of PCA20006 example to armgcc_s130_nrf51822_xxaa/armgcc_s110_nrf51822_xxaa and so on.

About this discontinued product-specific SDK(nRF51822 Beacon v1.1.1): The product download is a zip file with an MSI installer and things are pretty much windows oriented.

The main thing I wasn't able to understand is why the build targets of the examples there were for NRF51422.

Because it's not a dev board I'm unable to provide any info about why the beacon didn't start advertising anything, I only tried "app" firmware, didn't touch the bootloader

I got it to work

After searching the DevZone I figured I need to use an older nrfutil

dfu genpkg --application .\nrf51822_beacon_app.hex app.zip

And the uses nRF Beacon to update the firmware and got a success message.

I guess my next step now is to figure out how to use the toolchains and create my own hex file
