Adafruit Sniffer initialization error, Ctrl-R

[Aeneas]

I have the Adafruit Sniffer which is based on the nRF51822 Bluefruit LE Friend, which contains the Raytac MDBT40 . After searching and finding the CP2104 drivers, I can speak to the device but the BLE Sniffer software says I need to use Ctrl-R to re-program the device.  However, when I type Ctrl-R, I receive an error.  What is the step by step method to initialize this device, either with the BLE Sniffer software or with nRFgo Studio ?

Hey Aeneas,

Our sniffers does not support the Adafruit sniffer HW. We use an on-board SEGGER debugger chip on our nRF51 dongle to program the nRF51 with the sniffer FW. 

I suggest you get your hands on a nRF52832 DK (PCA10040) and use our v2 sniffer nRF Sniffer User Guide v2.1. 

Cheers,

Håkon.
