Im building a project which requires interchange of data between the two, but I dont know how to do it. Ive seen some examples online, but they all seem to be connecting an android device to the board. The ble sense is used for sensors and the 33 iot is in a motor carrier.
Welcome to the forum
Are you absolutely certain that you need to use 2 boards ?
It is very doable. The question is how and what protocol to follow. I do it a lot with CAN, 16 nodes or more is easily accomplished with a bus length of several thousand feet. Data is normally transferred in 8 blocks of 8 bytes, anything less is no problem. I am not sure what you are exactly doing or what your throughput will be but UKHeliBob's question should be checked into. Using one board greatly simplifies the code and everything associated with it.
Try putting a rough schematic together with everything on one board, do this after noting the perprial parts of the chip you will need, such as analog, PWM, etc.
