I am developing a product that requires an ad-hoc mesh network. I have a Raspberry Pi with a WiFi adapter, which I am attempting to use in an ad-hoc network with an iPad. Basically, I want to use the Raspberry Pi as an access point, but it is part of a mesh network, which is why I am using ad-hoc mode rather than infrastructure mode. I have found that the Raspberry Pi transmits beacon frames for a few minutes, allowing the iPad to connect to it. However, after about 5 minutes, the Pi stops transmitting beacon frames, and starts transmitting probe frames instead. In addition, it no longer responds to probe requests from the iPad. I have verified all of this on Wireshark. The problem only happens if no other nodes are connected to the network.
I've narrowed the problem down to a specific file in the Linux kernel: linux/net/mac80211/ibss.c (can't post link because I just joined.) What led me to this file is an error I saw in dmesg:
[ 2026.006693] wlan0: No active IBSS STAs - trying to scan for other IBSS networks with same SSID (merge)
