Hi, is it possible to have a Master Writer/Slave Receiver configuration via bluetooth with two arduino Nano iots? Long story short I'm wanting to have an EMG feeding bio-electric information to an Arduino that will in turn wirelessly relay that information to another Arduino across the room. I've seen similar things done with HC 05 bluetooth modules, but never with a nano iot alone. Any information is appreciated 
You can do even better. You can provide the information with Bluetooth LE as a service and get it with another Arduino or anything else that has Bluetooth LE.
You can start with the ArduinoBLE library. It has two samples sub sections. You need one central and one peripheral device.
The examples LED and LEDControl work together and show you what you need to do. Some Bluetooth LE knowledge will help you a lot understanding what is going on.
Feel free to ask if you have any specific questions.
