Tool/software:
Hi team,
For the HCI_LE_ReceiverTestCmd() I typically see 0x21 for the number of packets received. I am not in a chamber, so I assume the radio is picking up signals on the frequency that I configured the radio (which is 2402 MHz – channel 0) in my current environment. Therefore, if I went to a more controlled environment like a chamber where I can control RF environment, I would expect the number of packets received to increase or decrease. Is this correct? Do you know how long the LE Receiver Test runs once it is started? Does it run until LE Test End is sent (although the number of packets returned will be zero)? Or does it run for a fixed duration?
Is the implementation of the LE Test End command different in the CC2340 vs the CC2541? In our previous design with the CC2541 we would call HCI_LE_ReceiverTestCmd() and then call HCI_LE_TestEndCmd(). HCI_LE_TestEndCmd would return the number of packets received during the LE Receiver Test. But it seems the CC2340 operates differently - HCI_LE_TestEndCmd returns the number of packets received.
The CC2541 design is about 12 years old so things may have changed. If that is the case, we just need to communicate the change to the rest of the team and update our documentation.
Best,
Luke
