The EY-23A module has clear advantages: it supports SPP for PC Bluetooth communication and BLE 5.0 for mobile apps or WeChat mini programs. It can work with an EY-34 as a master to form master-slave communication with EY-23A as slaves. In EY-34 multi-connect mode, one EY-34 can connect to up to seven EY-23A slave modules simultaneously.

The EY-34 transparent-transmission module is based on Bluetooth BLE 4.2 and Bluetooth 3.0 standards. It supports BLE and SPP operating simultaneously, and SPP supports multi-connection as well as master/slave operation at the same time—there is no need to separately configure the module as master or slave.

5 16
In multi-connect mode SPP supports up to 7 SPP peer connections (Android or PC) plus 1 iOS phone. BLE also supports connections from Android or iOS devices.
