Chengdu Ebyte Electronic Technology Co., Ltd E104-BT5032A User Manual 1. Overview 1.1 Introduction Small in size and low in power consumption, E104-BT5032A is a serial-to-BLE module based on BLE 5.0 working at 2.4Ghz. It works as both Bluetooth master and slave. Based on nRF52832 from Nordic, the E104-BT5032A module is developed by Chengdu Ebyte. AT commands are available for parameter setting, thus operation is simple and fast. There are Bluetooth master, slave and observer modes.

Chengdu Ebyte Electronic Technology Co., Ltd E104-BT5032A User Manual In actual applications, the MTU value of different devices will be different. For example, the iPhone's MTU is 185 bytes, and users cannot change it. 2.1.3 Distance response for data rate With ceramic antenna，compared with PCB antenna, ble signal on external antenna has poor TX and RX ability. The longer the distance, the slower the data rate. 2.1.4 Module advertises data in multi-connection The module supports multiple connections.

Chengdu Ebyte Electronic Technology Co., Ltd E104-BT5032A User Manual 2.1.8 Solution to broadcast data problem This method is only for versions below V1.3, excluding V1.3. Problem description: For versions below V1.3, if the user sets the broadcast data to {0x01,0x02,0x03,0x04}, the actual scan result is {0x02,0x01,0x03,0x04} At present, it is compatible with the broadcast data of other models of BLE, which will be modified to {0x01,0x02,0x03,0x04} in V1.3.
