Hey everyone,
Just a heads up, as per our release topic Gen 3 improvements update 2/2/19 an issue in regards to causing a deadlock for the NCP is addressed as per device issue #3. I highly suspect this is the issue you are experiencing and that this should be resolved in v0.9.0-rc2.
For now, I would sit tight until you’re able to try 0.9.0-rc2 and see if this issue persists post update.
