PSoC4-BLE Integrated Test Code User Manual

Purpose:

The purpose of this document to explain the usage and features of the PSoC4-BLE Integrated test code (ITC)

Features

The firmware supports the following test modes

  1. MTK mode (AT like commands)
  2. BLE two wire mode (Only 1 Mbps supported for now)
  3. Regulatory test modes (button press based mode change)

Option 1 and 2 are recommended for regulatory tests if there is an UART port available, otherwise Option 3 can be used.
For qualification test and for testing using and standard Bluetooth testers, it is recommended to use the Direct Test Mode example project (which basically provides HCI over UART)

BLE two wire mode

This mode supports the 2 wire commands defined in the BLE specifications. This mode can be used with most test equipments to test RF-PHY.
Select the port pins of the UART component to match the target hardware to use 2-wire test mode. The baud rate is set to 115200 bps by default. It can be changed by double clicking the UART component from the TopDesign.cysch file and choosing the desired baud rate from the drop down menu in the baud rate field.Community-Cypress-PSoC-4-BLE-Integration-Test-Code-

Regulatory Test Mode

This mode can be used for regional regulatory testing like FCC, IC, CE, KC, MIC, etc,. This mode supports putting the Bluetooth device into various transmit and receive modes needed for regulatory testing. A button trigger is used to switch between various modes. Please configure the GPIO named Button to any available button/GPIO in the target hardware.
The radio starts in idle mode and cycles through the mode defined with each button press. The suffix indicates the frequency in MHz, RX indicates reception, TX
indicates modulated packet (burst) transmission, TXC indicates career wave
transmission mode. The device operates in 1 Mbps mode for the first cycle. After
completion of all the modes, the device restarts from DUT_RX_2402 in 2 Mbps mode.

MTK Test Mode

MTK mode allows users without sophisticated test equipment to put the put the DUT in any of the test modes simply by typing simple commands from HyperTerminal or Teraterm (or any serial port console)
MTK can be disabled by commenting #define MTK in Config.h
The following are the list of supported commands

Command Parameters Comment
TXP Channel, Power, Number of packets Transmits the specified number of DTM

packets in the specified channel at specified

output power level in dBm.

RXP| Channel| Puts the device in DTM receive mode in the

specified channel

RRS|  | Stops ongoing DTM mode
PST|  | Prints the current status
SPL| Packet length| Sets the length of the DTM packet
SPT| Payload type| Sets the payload type of the DTM packet
TXC| Channel, power, duration| Transmit carrier wave in the specified channel at specified power level in dBm for the specified duration
ADV| Channel, Interval| Transmits a single DTM packet once every

‘Interval’ number of BT slots.

2WC| MTK_ON/OFF| This is available only when both Two Wire
 |  | and MTK are enabled. TwoWire has the control on UART by default. This command with parameter 0 should be sent to change the control to MTK or parameter 1 to give the control to TwoWire when MTK has the

control.

---|---|---
RXC| Channel, RX_Window| Resets receiver in the specified Channel for RX_Window number of packets and prints the number of packets. This is repeated

until another MTK valid command is issued

SRP| Phy| Set the radio PHY to either 1 mbps or 2

mbps

TXM| Channel, power, duration| Transmit continuous modulated output in the specified channel at specified power level in dBm for the specified duration

The following table explains the valid values for each parameter

Parameter Valid inputs Default Comments
Channel 0 to 39 0 BLR RF-PHY channel
Power -18, -12, -6. -3,

-2, -1, 0, 3

| -18| Transmit power in dBm
Num. of packets| -1 to 65535| 1000| -1 for indefinite transmission
Packet length| 0 to 255*| 37| 255 bytes is supported only in devices with Bluetooth 4.2 support; otherwise, the

maximum length is 37

Payload type| 0 to 7| 0| 0  Pseudo-Random bit sequence 9

1  Pattern of alternating bits ‘11110000

2  Pattern of alternating bits ‘10101010’

3  Pseudo-Random bit sequence 15

5  Pattern of All ‘0’ bits

6  Pattern of alternating bits ‘00001111

7  Pattern of alternating bits ‘0101’

Duration| -1 to

| -1| -1 for indefinite transmission

Any other value is time in ms

Interval| 32 to 16384| 32| Specified number of BT slots (625uS) plus a random delay.
MTK_ON/OFF| 0 1| 1| 1  – Two Wire owns the UART port

2  – MTK owns the UART port

RX_Window| 100 to 65535| 1600| Timer is set to receive the number of packets
 |  |  | specified for each update of number of packets

received

---|---|---|---
Phy| 1 or 2| 1| 1-1 Mbps, 2-2Mbps

Examples:

  • TXP 19 3 1500 – transmits 1500 packets in Channel 19 at 3 dBm power level
  • RXP 39 – starts receiving DTM packets in Channel 39
  • RRS – stops DTM mode; prints the number of packets transmitted when issued after
  • TXP; prints the number of valid packets received when issued after RXP.
  • PST – prints the number of packets transmitted when issued after TXP; prints the number of valid packets received when issued after RXP.
  • SPL 37 – sets the packet length to 37 bytes
  • SPT 0- sets the packet type to PRBS9 sequence
  • TXC 0 3 1000 – transmits unmodulated carrier wave in channel 0, at 3 dBm for 1000 milliseconds
  • TXC 0 3 1000 – transmits modulated carrier in channel 0, at 3 dBm for 1000 milliseconds
  • SRP 2 – Sets the PHY to 2 Mbps
  • ADV 39 32 – transmits one DTM packet in Channel 39 every 32 BT slots
  • RXC 10 1600 – Starts the receiver in Channel 10, sets timer to receive 1600 packets
  • (1600*0.625 us), stops the receiver after the timer interrupt, prints the actual number of packets received. This is repeated until the next MTK command is received.
