Cypress Semiconductor Class II Change Letter Date: 2016-09-07 To whom it may concern, Request for Class II Permissive Change Product Name: EZ-BLE PSoC Module FCC ID: WAP4008 Model No.: CYBLE-014008-00; CYBLE-214009-00; CYBLE-214015-01 IC Certification Number: 7922A-4008 Modification: 1. Modules CYBLE-014008-00, CYBLE-214009-00 AND CYBLE-214015-01 have the same PCB, periphery parts and the encapsulation of the main chip. The difference of the main chip is Bluetooth version it supports. 2. We declare that we have applied for Existing Family for ISED: 7922A-4008. The model number is CYBLE-214015-01. Module IC Part Number CPU Flash Package Bluetooth Speed Size version (MHz) (KB) CYBLE-014008-00 CY8C4247FNI- 48 128 WLCSP- 4.1 BL483 68 CYBLE-214009-00 CY8C4248FNI- 48 256 WLCSP- 4.1 BL483 76 CYBLE-214015-01 CY8C4248FNI- 48 256 WLCSP- 4.2 BL583 76 The RF character of these three modules is the same.

Cypress Semiconductor Specifications of EUT Operating Frequency 2400-2483.5MHz No. of channel 40 Channel Spacing 2 MHz Modulation GFSK Transmit Power (ERP) 2.16 dBm / 1.64437 mW Data Rate 1 Mbps Antenna Type PCB Antenna Number of Antenna One Antenna Gain -0.5 dBi Supply Voltage 1.9 V to 5.5 V(3.3V nominal for test jig) Dimension 11 mm x 11mm Environmental Operating: -40 ℃to 85 ℃ 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. 2/ 4
