I’m trying to send the present latitude and longitude from an android tablet to an Arduino Uno through Bluetooth. I would like send the latitude coordinates as 64 bytes, and the longitude separately as 64 bytes. I’ve already connected/paired the tablet with the bluetooth module: https://www.sparkfun.com/products/10393
…but I am unsure how to proceed. I read something about big endian and little endian, but do not know which one my tablet uses(Nexus 7). How would I transmit the data between the tablet and the arduino? Would I have to use Serial.readBytes()? If so, could you please provide some sample code. I am in Grade 10 and do not have much coding experience, so any help would be appreciated.
