Programming nRF51822 smart beacon kit

[Sarah]

Hi,

Where can I find the instructions on what tools need to be installed to reprogram the nRF51822 beacons? I haven't been able to find it in the documentation provided with the kit. I only own the smart beacons and do not have the development kit.

Thanks

In order to program the beacon not using DFU, you will need a programmer. I would recommend you to take a look at the thread "How can I program nRF51822-Beacon" .

What's the voltage on your beacon kit? The JLink-OB on the NRF51-DK needs to see 3v (or more) on the external (Debug Out) VTG before it will sense the board and bypass the DK's nrf51822.

Other things to try, powering up the boards in a different sequence and only opening NRF studio after the boards are all connected. I believe once JLink has connected to a target, it then ignores other targets so you need to get it switched to external mode and connected to your board before the driver starts interrogating it.
