title: Bluetooth LE - Single Characteristic with Large Payload or Multiple Characteristics with Small Payload?
body: <p>I'm using Bluetooth Low Energy to connect a device in Central mode to several devices in Peripheral mode. The Peripheral device would need to send 4 strings (all fewer than 20 characters) to the Central device.</p>
  
  <p>Is it better to create 4 characteristics and have the Peripheral make 4 write requests to the Central? Or is it better to have 1 characteristic and combine all 4 strings into a JSON object as to make only 1 write request?</p>
  
  <p>Simply put - is it better in this instance to small chunks of data multiple times or send a larger chunk of data once?</p>
  
  <p>Which approach would be better for allowing as many Peripherals to connect to a Central as possible? Does it matter?</p>
  
  <p>Thanks.</p>
