CC2650: CC2650: research transmit Bluetooth Low Energy

lxrd knows

Part Number: CC2650

Hello.

I'm investigating the transmission characteristics of BLE between two CC2650lp.

Im flashed one board host_test and second project zero then via app Btool and command HSI_ReadRSSI() tested the dependence of the RSSI level on the distance.

Now i want to research something parameters else, for example - immunity noise: transfer N-packets from host_test to simple_peripheral and tested the dependence of the Packet Error Rate on the distance between the boards.

How can I do that? And what transmission BLE parameters can I check yet?

Hello,
You can set up packet error rate test in SmartRFStudio. That way you do not have to create any custom firmware on CC2650.

To implement per test in simple_peripheral you can refer to the TI_BLE_Vendor_Specific_HCI_Guide.pdf and the command HCI_EXT_PacketErrorRateCmd. This require you to write some code and Note: The counters are only 16 bits. At the shortest connection interval (7.5 ms), this provides a little over 8 minutes of data before the counter overflow. This is based on the connection event packets that occur at every effective connection interval.
