Serial preventing boot about homespan HOT 5 CLOSED

I should also add that the code I'm using on this device is the tutorial "15-RealPushButtons" with minor changes.

Hmm. I think I understand the problem but unfortunately not sure how to fix it. It may be possible to use the Arduino if(Serial) command to check whether the Serial port is active, but even if this works this would likely require every Serial.print() command to check as well to avoid hanging. I don't have an FTDI so unfortunately can't test this hypothesis.

I had the same thought but I'm struggling to understand why it is blocking. I'm not sure how it's any different to any prebuilt board. I'll need to read more about the blocking nature of serial with FTDI.

With the Wifi bug fixed, my need to use the serial commands is lessened.

I will provide any updates if I get some.

I have localised the issue to within the homespan.poll() function where it checks for any available serial. If I comment out the if block, the module works. See below:

Solution for this specific case was to add a high value resister between RX and VCC to pull the floating RX line high.
See comment in issue 131 for more detail.

Closing this as it is now being tracked in #131.
