Hi,
I have bought an nRF52DK (PCA10040 v3.0.0), which has an nRF5340 chip.
I want to use it as BLE Sniffer to debug my application, but Wireshark is giving me an error "FIFO while trying to access the nRF 52 DK.
.
I followed everything written in the documentation from:
https://www.nordicsemi.com/Products/Development-tools/nrf-sniffer-for-bluetooth-le
I installed the sniffer_nrf52dk_nrf52832_4.1.1.hex into my nRF52 DK.
Wireshark is able to detect the board at COM10.
I'm running Wireshark as an admin too.
My current setup:
Intel(R) Core(TM) i5-6300U CPU @ 2.40GHz 2.50 GHz, 8GB RAM
Windows 10 Pro 64bits
Python: Python 3.9.10
WireShark Version 4.0.5
Result from testing in the Windows cmd "nrf_sniffer_ble.bat --extcap-interfaces"
