How Can I connect nRF51822 to a weighting scale?

adrianlee

I want to connect Bluetooth Smart chip to a weighting scale, read the data and send it to a phone. Is this possible and what requirements there are for the scale?

    I guess the only requirements for the scale are that you must be able to read out the data from somewhere, and that the voltage levels are high enough. I doubt that regular weighing scales come with any low level communication interface like SPI or TWI, but maybe you are able to decode the 7 segment display information?
