burn hex and reconnect arduino

ouki-wang commented 6 years ago

My goal is to connect this board. After an exception occurs, I can use python to burn firmata.hex and then connect again. Reconnect again with the following error：

using com COM31

Initializing Arduino - Please wait... Arduino Firmware ID: None Analog map retrieval timed out.

Do you have Arduino connectivity and do you have a Firmata sketch uploaded to the board?

I don't understand what your program does. I noticed that the baudrate being reported is 115200. Firmata expects 57600. If you are trying to integrate avrdude with pymata-aio, you may be mixing asyncio with non-asyncio code which can be difficult to do.

MrYsLab commented 6 years ago

If you are not combining asyncio and non-asyncio, then try setting the arduino_wait parameter to some high value like 30. If that works, adjust it down to a smaller value.

MrYsLab commented 6 years ago

I am closing this issue since I do not believe your problem is being caused by pymata-aio. If you disagree, please provide some detailed information about your application (like the source code, instructions on how to use it, etc.), and I will be happy to reopen and investigate your issue.
