I have multiple devices that working with this system:

Linux Variscite imx6 Linux 4.9.88-10180-gaaecf09-dirty #2 SMP PREEMPT Wed Dec 26 14:04:36 IST 2018 armv7l armv7l armv7l GNU/Linux

with WL1837 wifi module : chip.fw_ver_str = Rev 8.9.0.0.79 chip.phy_fw_ver_str = Rev 8.2.0.0.242 wpa_supplicant v2.6

I see that we have latency sometimes 10 sec and I need to improve that. When I installed tcpdump on this linux and recorded pcap file I saw that this devices communicating with each other via XID LLC tcpDump PCAP

Captured PCAP

Why this is happening and how I can stop the devices communicating with each other? I need that the devices will communicate only with the gateway.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
