Part Number: CC2564
CC2564BRVMR module(BT) gives error reply when MCU tries to create connections.
I tried to detect the BT pins logic using Logic analyzer and scope, such as TX/RX pins.
MCU sends the correct command data to BT, but BT replied seems crazy data.
This capture shows only the BT TX pin reply(0xFF), I assume the BT works un-normally.
You maybe ask "Are you sure you sent the correct data?"
I am pretty sure, because I can see the correct data using logic analyzer and I also use the BT TX_DBG pin to see thee correct configurations
Here is the TI Logger shows as blow tables

I donot know what is the difference between Process type: Weak and Process type: Nominal.
But we can see BT accepted the command and gives the reply
HCI Send Event: HCI_COMMAND_COMPLETE_EVT
BT send the wrong data from the TX pin.
My questions:
1. How to see what kinds of raw data the BT sending or receiving using the TI Logger or other SW tools?
2. How to confirm what is the reason cause this problem? It is so weird about this BT.
We have ZT9Y, ZKD1 and ZKD2 BT modules.(Assembly lot code)
ZT9Y can work normally, but ZKD1 happens this issue.
