Will also be interesting to see what kind of license changes come about due to this. Autodesk has recently been granting a lot of access to really good software (Fusion 360, etc) to hobbyists at no charge. I know we already have a freeware license for Eagle, but it would be nice if they removed...
Yes, I am quite sure they are connected, but the reason for them not being connected to the pins is that I manually drew the "ground plane" around the connector using the via's and tracks. I have specifically put down a "keepout" region around the connector so the ground plane would not...
I have personally found that sometimes the cell tower closes the connection from their side, and that causes the PDP DEACT message. You should simply be able to re-establish the connection using the same steps you follow to setup the connection the first time. Starting from AT+CGATT=1 should...
In regards to the antenna trace, I just want to make sure everyone understands the attached design is how I want to do it in future... below is the current layout that is giving me problems.
*Bottom ground plane not shown
As requested, here is the full design:
To understand why I have...
