I received an unverified report that the serial console was “broken” by the firmware update from 1.1.8 to 1.1.12. Specifically, that the GTM unit no longer responds to commands on the serial port configured at 9600 8n1. Bluetooth pairing appears to work OK, however without a console it’s hard to tell.
Is this a known problem and does anyone have a solution?
I’m having the broken unit sent to me for further investigation and have instated a firmware freeze to 1.1.8 until clarification, but was wondering if anybody else is experiencing this, as I found no mention of the problem on any public forums.
