PB2

That part of the library is commented out because Arduino core developers are stupid and have different SPI APIs across different boards - making SPI data transfer libraries like this...

This error doesn't make sense considering the first argument for `SPITransfer::txObj()` is templated: https://github.com/PowerBroker2/SerialTransfer/blob/c596233371af2735c1a20be8f70f5e5ce30bb278/src/SPITransfer.h#L27-L49 I honestly don't know what's going wrong - perhaps someone on the Arduino forum would be...

There's a chance you already have a phone or laptop that is already connected to the OBD2 scanner and won't let the ESP connect. Try turning off all other BT...

I use [this one](https://www.amazon.com/gp/product/B005NLQAHS/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) and it works like a charm

If your OBD2 scanner is BLE, then it isn't supported by this lib, unfortunately

Thank you for the proposal and kind words - I'm glad you find the software useful, and I'm super appreciative of your contributions to the projects. Here's my 2 cents:...

@drmpf Let me know if you want me to merge

The way to fix this would probably to have a debug flag - something for users scripts to control when you want these debug prints and when you don't. I...

@odwdinc Is this repo abandoned or is it still maintained?

There are a couple places where the class can detect a good connection: In `get_response()` we have: https://github.com/PowerBroker2/ELMduino/blob/5d041617e79bad7487e69f722f8719f9f6ef4155/src/ELMduino.cpp#L2313 And in `initializeELM()` we have: https://github.com/PowerBroker2/ELMduino/blob/5d041617e79bad7487e69f722f8719f9f6ef4155/src/ELMduino.cpp#L126 https://github.com/PowerBroker2/ELMduino/blob/5d041617e79bad7487e69f722f8719f9f6ef4155/src/ELMduino.cpp#L148 https://github.com/PowerBroker2/ELMduino/blob/5d041617e79bad7487e69f722f8719f9f6ef4155/src/ELMduino.cpp#L169
