[Bluetooth protocol]：BLE 5.0
[Communication distance]：150m
[Product size]：13*19mm
[Introduction]：E104-BT09 Bluetooth module is a Bluetooth-to-serial slave module based on the BLE 5.0 protocol developed by Ebyte based on the Telink Micro TLSR8208BER chip. It is small in size, has low power consumption and works in the 2.4GHz frequency band. The Bluetooth module uses ordinary AT commands to set parameters, and the operation is simple and fast. The Bluetooth to serial port module supports slave role, Bluetooth broadcast, data transparent transmission and wireless configuration. Modified Bluetooth modules can be widely used in smart wear, home automation, home security, personal healthcare, smart home appliances, accessories and remote controls, etc.
