Thank you very much jock, I still don't have all needed knowledge, but I am lucky to have the H5 working, so before reading your answer I tried two script that are in my H5 and not in the H3 image, such as /etc/default/ap6212 and /etc/init.d/ap6212-bluetooth. Especially the last is invoking, among the other things, just the hciattach you were mentioning, and also devmem2* and rfkill that were missing in the h3 environment (very strange the rfkill missing!) Now, invoking ap6212-bluetooth by hand, I finally had the bluetooth working, but wifi stopped working and I had to relaunch it via armbian-config (deactivate/reactivate with my wifi ESSID). Now the last missing piece of the puzzle is: who and when should launch /etc/init.d/ap6212-bluetooth at startup, especially in order not to mess up bluetooth and wifi?** I'm continuing to investigate, anyway thanks a lot for the very useful overview *: I took it from here https://github.com/henla464/WiRoc-StartupScripts/blob/master/devmem2 , thanks to Henrik Larsson **: UPDATE: I found how it works and used sudo update-rc.d ap6212-bluetooth defaults that makes the correct links for the boot execution levels described in the script header. Now everything works, bluetooth+wifi. Thank you for having triggered the right path of searching! ap6212 ap6212-bluetooth

Hi I'm adding details to my question, if somebody can help it would be very appreciated. To resume, my problem is that I have a Orange Pi Zero Plus2 H3 with Armbian Buster mainline based kernel 5.10.y, and Bluetooth is not working (hciconfig -a does not report any controller); I also have a Orange Pi Zero Plus2 H5 (64bit) with Linux orangepizeroplus2 4.17.2-sunxi64: here Bluetooth is working correctly, with hciconfig -a reporting a controller with its parameters. Here is the H5 dmesg output for the part related to bluetooth: [...] [ 4.789119] cfg80211: Loading compiled-in X.509 certificates for regulatory database [ 4.797546] cfg80211: Loaded X.509 cert 'sforshee: 00b28ddf47aef9cea7' [ 4.851379] brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac43430-sdio for chip BCM43430/1 [ 4.879043] EXT4-fs (mmcblk0p1): re-mounted.

Hi everybody, I'm using the Armbian Buster mainline based kernel 5.10.y image on https://www.armbian.com/orange-pi-zero-plus-2-h3/ but I also tried the Focal one. I searched the forum deeply and I saw that someone in the past (forum post closed, otherwise I would have continued there) managed to have BT working by "faking" the /lib/firmware/brcm/brcmfmac43430-sdio.bin, that boot tries to load having error -2, copying the ap6212/fw_bcm43438a1.bin in its place. But it seems that it only works with legacy images, infact, with my mainline image I keep failing. Which legacy image should I look for? I was thinking that https://www.armbian.com/orange-pi-zero-plus-2-h3 already lists customized images, but I think I completely misunderstood. Thank you for any help
