Firmware Sketch Firmata Version not Found #27

Closed thomasarmstrong98 closed 3 years ago

thomasarmstrong98 commented 3 years ago

Hey, using the latest update of pymata4 and having an issue with error: "Firmata Sketch Firmware Version Not Found". I checked the docs and saw the troubleshooting steps although I am not sure what the problem is exactly. I am trying to retrieve data from an I2C temperature sensor on an Arduino. I can run tasks on the arduino using pyfirmata - so I know that the Firmata sketch is installed correctly but it is not picking it up when using pymata4. It is identifying the board but that's about it.

Wondering what steps I can take to fix or troubleshoot this further? Thanks.

If you are using pyfirmata then I am assuming you are using StandardFirmata. I recommend using FirmataExpress which runs at twice the link speed of StandardFirmata. However, if you wish to still use StandardFirmata, you will need to manually set the baud rate to 57600 when you instantiate pymata4.

Please let me know if you are able to resolve your issue.

Thank you, I worked this out eventually around 5 minutes before your response! First time working with microcontrollers, so everything is a bit new - thanks for this great package!

@thomasarmstrong98 I am glad it's working. If you need to extend the sketch to support devices that are not i2c, you might want to check out Telemetrix. It is similar to Firmata but simpler to extend. The Telemetrix client commonly supports Arduino boards via serial, the ESP-8266 via WiFi, and STM32 boards via serial. There are separate sketches for each of the board types. Again thanks for letting me know and closing the issue.
