Internalblue Typerror at startup on Raspeberry pi 4b #53

Closed delmarocks closed 3 years ago

delmarocks commented 3 years ago

Does anyone encountered this error on raspeberry pi 4 b 64bit version when running internalblue cli? I followed all the installation process in the documentation but still this error shows up.

This issue is due to a change in the last version of cmd2. You can downgrade to cmd2<=1.5.0 to solve this issue.

Thanks @cchaine for pointing this out. I already bought a Raspberry Pi 4B these days and wanted to check if InternalBlue runs on it, so I might as well run into the same problem :)

delmarocks commented 3 years ago

Thankyou @cchaine it did works by downgrading cmd2 to 1.5.0. 🙂

No worries. This problem has been fixed on master. You can close this issue.

Checked everything with @cchaine 's pull request on a Raspberry Pi 4B and it just worked for me :) Tested on an up-to-date Raspberry Pi OS Lite.

However, I noted that reading the Patchram Enabled Bitfield does no longer work with the current firmware. The return status of HCI is Status: Invalid HCI Command Parameters (0x12) and thus, commands like info patchram just time out. That is definitely a firmware issue, but depending on what you want to do on that chip, you might need to downgrade the firmware patch file.

Okay, quick fix to downgrade the firmware on the Raspberry Pi 4B:

cd /usr/lib/firmware/brcm/
cp BCM4345C0.hcd BCM4345C0_orig.hcd
wget https://github.com/RPi-Distro/bluez-firmware/blob/96eefffcccc725425fd83be5e0704a5c32b79e54/broadcom/BCM4345C0.hcd?raw=true
mv 'BCM4345C0.hcd?raw=true' BCM4345C0.hcd

Then reboot to load the old firmware. I will update the readme as well :)
