Hello,

This is common behavior as the receiver accumulates the total count of received packets from the moment the test starts until TEST_END.

''The PC starts the test by setting up the DUT in receiving mode and the TESTER to transmit packets. The test parameters, including the frequency, packet length and packet type, must be matched between the TESTER and DUT. Otherwise, the test fails. At the end of the test, TEST_END is sent to the TESTER to stop the transmission and then to the DUT to stop reception. The DUT responds with the total number of packets received.''

I had to use another device to send BLE packets for RX test. What I have seen is the BLE receiver shows accumulated packets if I keep sending packets form the TX device. For example, when I send 10 packets, I can see the RX device shows 10 packets, but when I send another 10 packets, then the RX shows 20 packets and so on. Is it what I should see from the receiver?

Hello,

''Do you have an example of waveform file in Matlab format for testing?''

Sorry, we do not have it.

The address used in radio test is not the same as for DTM. It's not using the standard Bluetooth sync word. The instrument you are using is not a Bluetooth tester so it's not immediately possible to use that. It is better to use a DK with radio test as generator.

or Rohde & Schwarz can provide the waveform files for BLE testing.

My Sig. Gen can generate data packets. Somehow it still doesn't work, 0 packet received

I run commands:

#start_channel 2

#start_rx

#print_rx

RF level = -60dBm

Do you have an example of waveform file in Matlab format for testing?

Thanks,

Hello,

If the signal generator you have can generate BLE packets, you can use radio test to count the number of received packets.

Hello Kazi,

I think those Anritsu and CMW500 are radio test sets, which allows to test both TX and RX performance. The equipment, which I have now is a pure Sig. Gen, which is R&S SMCV100B. Let me know if you have an idea how to test RX sensitivity with a stand alone Sig. Gen.

Thanks,

Hello,

It is possible. You need to use a BLE tester, like Anritsu or CMW500 if you want to use DTM. You can try radio_test sample also if you have spectrum analyzer.

Thanks.
