I have a Bluz DK and a Gateway Shield. The DK connected to the Gateway shield and everything was working fine for a couple of weeks.
I made a minor change to the Electron on the Gateway and uploaded the new firmware. Now, the DK would not connect and keeps flashing green. The change I made was not related at all to the Gateway parts.
Also, I tried connecting to the DK through the phone (it should not connect because it is in SYSTEM_MODE(MANUAL); mode). It did connect! Even though it is breathing cyan, it cannot be seen on the IDE. It is also not found in a Bluetooth scan.
What could have happened?
Thanks in advance.
