## Description

BLE 5.0 module for low-power wireless connection between Arduino and other Android or iOS boards and phones, based on TI CC2640R2F. Works as Master and Slave, supports AT commands type HM-10, provides authentication and encryption for more secure connections. Adjustable RF power and coverage up to 100 m in open field, power supply and logic level 3.3 V.
Bluetooth BLE 5.0 module, compatible with Arduino and other development boards, which uses the integrated master from TI CC2650R2F. It is compatible with Android and IOS phones but may be incompatible with some Bluetooth 2.0 SPP devices.
You can use the "DSD TECH Bluetooth" applications from Google Play and the App Store.
This module works both as a Master and as a Slave.
