Unstable communication with a razberry2 (blue card) and pi4.

[boggibill]

Hi there.

I have installed buster on a pi4 and zwave.me to it. The communication seems to be stable, using a 14 units setup it most of the units included into the device to be dead. Meshing does not work and it seems and im having problem including more devices. I have tested with multiple pi4's and multiple razberry blue cards with the same issues.

I have tried disabling bluetooth adding the following to /boot/config.txt
dtoverlay=disable-bt
enable_uart=1

I have also tried different version of zwave.me:
3.1.0
3.0.6

Event tried degrading to 2.3.8.

When testing the same on a pi3b+ it all works as supposed to.

For some reason I just can't get it to work.

Other information:
I have tried updating the firmware on the pi4 using rpi-update and I have installed the latest boot firmware to be able to boot a pi4 using USB boot following this instructions:
https://www.raspberrypi.org/documentati ... teeprom.md


Anyone here that could give me some guidance on how to debug why the communication is working so bad?

Just an update if anyone experiencing the same problem.

What helped was installing the razberry image found here:
https://storage.z-wave.me/z-way-server/

After that upgrading the buster image to be bootable using usb on pi4.

For some reason upgrading the provided image instead of installing buster, upgrading it to be bootable for usb and install zwave.me to it.

Im not sure if the provided image is fitted somehow to support pi4.

I have been able to use the Razberry board with PI 4B's. There is probably an issue in your /boot/config.text file that was preventing it from working.

I have this in mine:
