coming Bluetooth: hci0: Frame reassembly failed (-84) while connecting bluetooth

in flag

Downloaded and flashed the "ubuntu-20.04.2-minimal-armhf-2021-02-07.tar.xz" file as rootfs to embedded board and trying to connect to bluetooth using below commands.

$ hciattach -t 30 /dev/ttymxc0 any 115200 flow
$ hciconfig hci0 up
$ hcitool scan

sometimes its connecting and able to scan the devices but sometimes its throwing errors while giving hciattach command.

    root@arm:~# hciattach -t 30 /dev/ttymxc0 any 115200 flow
    Device setup complete

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.
