Hello
I just bought a NRF51422 (PCA10031 v1.1.0) dongle. It worked for sniffing, but after I upgraded the bootloader as indicated in the MBED post (developer.mbed.org/.../), it does not work anymore.
So I understand that MBED bootloader is not suitable, but I can't find a vanilla bootloader to restore my dongle. I tried to flash the sniffer firmware but it does not work... and nrfgoStudio never see my dongle...
How can I find a factory bootloader ?
Thx in advance :)
