Hello,

I am using a Raspberry Pi 4 running Buster 10. I’ve seen this problem asked on this forum recently without any answers. When running the install script, the system reboots, but the zymbit device is still blinking rapidly which indicates it is not paired. All files have been downloaded correctly, I tried running one of the python test scripts, but it fails. I’ve rebooted the device many times and have run the install script many times.

Edit: Yes, I have enabled I2C, and I believe I have switched cpu scaling from ondemand to performance but I do not know how to verify this is the case.
