rf51 dongle dev kit - sd_rpc_open hangs

[ble_dev]

Hello,

I just got an rf51 dongle (usb) dev kit. I have installed the latest SDK, JLINK drivers, nrfgo studio. I copied the firmware .hex file into the JLINK drive as per the readme file. I built the multilink example using MS Visual Studio Community 2015. When I run the sample, the call to sd_rpc_open never returns. Am running Windows 7 64bit.

Note sure if this is relevant but when I run nrfgostudio, it detects the dongle, asks if I want to update the firmware to the latest version. When I say yes, the firmware update always fails right at the end (last 5% or so).

Thx

I would make sure that the firmware on the Segger chip is correct. You can download the firmware here. You have to start the nRF51 Dongle in bootloader mode by holding down the button while inserting it into your computer( should now appear as BOOTLAODER). Then copy the firmware image into the BOOTLOADER drive, pull it out and then re-insert.
