MKW30Z FCC, EU CE qualification

lucianfiran — Wed, 17 May 2017 09:20:37 GMT

KW40Z_Connectivity_Software_1.0.1 (KSDK_1.3.0); IAR 7.50

2.4 GHz Bluetooth Low Energy version 4.1 compliant

From what I understand the FCC CE compliance test for a product requires 3 samples:

1. normal config, end user configuration

2. radiated config - some test software that enables the product to emit at max power

- max chip power or software set power in end user product ?

MKW30Z Programmable Transmitter Output Power: -18 dBm to +5 dBm

- the chip should send pseudo-random data continuously on each channel at max power

- the chip transmits only in one modulation GFSK ?

- the chip should transmit each data package (DH-1, DH-3, DH-5) Is this request applicable for MKW30Z ?

There are different data packages that can be tested ?

- does the chip uses different data packages, there is a test mode to enable them ?

- transmit on each channel - what channels does the MKW30Z chip uses - can we enable / disable them in test mode ?

3. conducted configuration - coax connector on antenna port (SMA or MMCX, ...)

- I assume the same connector as in development board (MKW40Z FRDM)

- some info about antenna gain

MKW30Z chip Bluetooth module can be put in some "Test Mode" for radiated config for FCC, CE tests in the SDK ?

Hi Lucian,

For testing BLE radio, there is the HCI Application in the connectivity software that can be used to test the radio with HCI commands. Please take a look at this document that gives an overview on how to test KW40Z for FCC/ETSI Certification. Let me know if you have a question.

The HCI app is located at:
\KW40Z_Connectivity_Software_1.0.1\ConnSw\examples\bluetooth\hci_app

Hi Gerardo,

In summary:

Channel count: 40x (BLE Channel 0 to BLE Channel 39)
Modulation: 1x GFSK (1 Mbps GFSK modulation)
Data packet types: 2x advertising and connection

Total max 80x tests.

Connect some serial convertor to RS232 on following pins:
32 Laminate QFN
TX Pin31 PTC17 or Pin27 PTC2
RX Pin32 PTC18 or Pin28 PTC3

Port from MKW40Z to MKW30Z the hci_app
\KW40Z_Connectivity_Software_1.0.1\ConnSw\examples\bluetooth\hci_app

Send via terminal:
-> 01 03 0C 00
For advertising
-> 01 1E 20 03 00 1F 00
....
-> 01 1E 20 03 27 1F 00
To send PRBS9 = x^9 + x^5 + 1 on all channels as 31 bytes lenght packets.

For GATT communication
-> 01 1E 20 03 00 14 00
....
-> 01 1E 20 03 27 14 00
To send PRBS9 = x^9 + x^5 + 1 on all channels as 20 bytes lenght packets.

For PRBS15 = x^15 + x^14 + 1 the last byte should be modified from 0x00 to 0x03

Best Regards,

Lucian
