Question
I am looking for a wireless controller with only Physical layer
I am trying to learn wireless firmware development.For that I am looking for a microcontroller with only Physical layer(ie when I place an ASCII character 'a' in an address it takes its binary value and transmit it as RF Signals).All other layer should be firmware iimplementation.I don't want any libraries pre-built because I want to built it from scratch.The controller should not have any packet or frame size limitation and entire packet right from Premeable to CRC should be cutomizable from firmware Should be compatible with 2.4 GHz WiFi and Bluetooth protocol.Please suggest a suitable controller and if possible share me the documents of the controller
