There are a lot of discussions on Raspbian and monitor mode, but I can only find scarce information about promiscuous mode. How do I put a Wifi interface in promiscuous mode? I'm looking to capture Wifi request probes while still associated with a network and otherwise not affecting that connection.
Current dongle is based on the Realtek RTL8188CUS chipset, but happy to buy any other dongle that makes this easier.
(Ultimately, the intent is to consume Wifi request probes in Python. Scapy seems like the appropriate choice.)
