Change Description Product Name: EZ-BLE PRoC Module FCC ID: WAP2005 IC Model No.: CYBLE-222014-01/ CYBLE-222005-00 IC : 7922A-2005 Modules CYBLE-222005-00 AND CYBLE-222014-01 have the same PCB, periphery parts and the encapsulation of the main chip. The difference of the main chip is Bluetooth version it supports. Module IC Part Number CPU Flash Package Bluetooth Speed Size version (MHz) (KB) CYBLE-222005-00 CYBL10573-76FNXI 48 256 76-WLC- 4.1 SP CYBLE-222014-01 CYBL11573-76FNXI 48 256 76-WLC- 4.2 SP The RF character of these two modules is the same. 1/2

Below is detailed difference between BLE4.2 and BLE4.1 chip: 1) 4.2 has improved security compared to 4.1 – this is ECDH on top of AES-128 in 4.2, whereas 4.1 is AES-128 only. This allows for transfer without having to exchange keys over the air. ECDH essentially embeds the key changes into the data transfer. 2) 4.2 has improved privacy compared to 4.1 – MAC address changes after a period of time for the BLE device. This is the same in 4.1 and 4.2, however in 4.2 the MAC address changing is happening in the link layer (where it was done in the GATT layer in 4.1). This change makes it so that you can use the feature without waking the entire system/stack. 3) Increase the maximum packet length from 37 bytes to 255 bytes.
