CC2650 Packet Error Rate Test Quick Start Guide
Mode menu
In the mode menu, you can select which device is transmitting and which is receiving:

BLE Transmitter

BLE Receiver
After selecting "BLE Receiver", the device goes directly into receive mode and is ready to receive
packets.
Only let 1 PER test device with the advertising address 0x264026402640 transmit packages at the
same time, as the receiver are based on recognizing a sequence number in the payload and will get
restart the receive statistics if packets with a lower sequence number arrives.
TX Power
When selecting "BLE Transmitter", you can also select which output power you would like to
transmit with. Currently, the following options are available:

0 dBm

+5dBm
Burst size
After selecting output power, you can also select the number of packets you would like to send in
one test.
This is configurable between 1000 and 1 000 000 packets.
Packet rate
To test the device with different data rates, you can also select how many packets per second you
would like to send.
This configures the 32k RTC timer to trigger an interrupt a number of times per second to send a
package.
Note:
The PER test packet rate setting is currently using a low frequency clock derived from the 48MHz
clock, meaning the packet rate is not 100% accurate. The RTC frequency is therefore 31.25kHz
instead of 32.768 kHz but this will be changed in a later release.
TX Idle
The PER test is now ready to send packages but has not yet started. To start sending packages, press
RIGHT/SELECT.
You can restart the test at any time by pressing RIGHT or SELECT.
