Need a mini (width not more than 1 cm) wireless communication structure, can carry on the data transmission and single chip microcomputer, communication distance can reach more than dozens of meters, best used to do a small volume of works, have who can give me some advice? Is relatively simple for beginners, best can be off-the-shelf modules, also can use chip assembly, thank you very much,

Esp8266 series or esp32 series wireless module, bluetooth, support 2.4 G and there are a lot of models, itself is a MCU, also can be a wireless module, using the at command to passthrough, some models can be an external antenna, small size,
If the width must be limited within 1 cm, try not to bring a peripheral circuit chips,
