Am using DeviceOS 1.5.2 and suffering the same “long term” issue of flashing cyan and not recovering connectivity.
Is there a definitive reason for this ongoing and frustrating issue?
Dare I say this is my last problem to solve before I am comfortable going into production…
The number of contributors and contributions to this post is a testament to how bad this issue is.
IMHO it is really poor that after all these years that it has not been sorted by official Particle advice, and/or DeviceOS fix.
