You should only have to reset the baud rate if you factory reset the bee or update it’s firmware – neither of which you can do by accident.

In the case of a lot of inexpensive sensors sold as breakout boards, the Mayfly connects and talks directly to the sensor, but most of the not-bare-circuit sensors have black-box layers between the raw…[Read more]

Yes I2C is too short range for the applications I have in mind, but I have some experience with RS485 so that sounds like a good option.

I’m not very familiar with your ecosystem, but would using ModularSensors require the Mayfly to be connected directly to the sensor? So if my sensors are natively I2C, I…[Read more]
