Hello, does MMR have a possibility to send data using wires, like I2C or SPI? We've wish to integrate MMR into our PCB and there is no need for the BT communication. Thank you
Yes it does. Please read our tutorials and datasheets.
I2C contacts are on the board, but the documentation suggests that they are there for adding sensors, not communication with the MMR. I can't find any tutorial about wired communication, can you point me to some example?
Well you can't send commands to the MMR via the SPI/I2C.
What we mean by "adding a sensor" is that the SPI/I2C line is to add peripherals and sensors to the MMR on that line.
Take a UV sensor for example. You can add it to the MMR SPI/I2C bus and then send it commands as per the UV sensor spec.
Here is an example:
1. You could add this sensor to the MMR (attach the power and I2C proper)
2. Then you can read the datasheet and information here:
3. Learn how to interact with it and the I2C commands you need to send to retrieve UV data.
3. Then implement it on the MMR:
Thank you. As questioned - we wish to use SPP/I2C intead of the BT for communication with our gateway. Therefore: MMR using SPP/I2C sending all of its sensor data to gateway. Based on what you have wrote that is not possible, right? I just wish to be 100% sure because we are in hurry currently, sorry.
No this is not possible.
