I was checking the operation waveform of the example with an oscilloscope.
After sending the HCI_RESET command, RTS does not return from High to Low during the response as shown in the figure below, and the response data is interrupted.Is this normal?
What can I do if this is not normal?
Correspondence with each signal.
A0:TX(OUT) / A1:RX(IN) /
Ch1:BT_REG_ON(OUT) / Ch2:RTS(OUT) / Ch3:CTS(IN)
Solved! Go to Solution.

It was caused by mixing paths for different modules in IAR-EW's optional include settings.

Hi @hi118
Could you please clarify if you are referring to the RTS of the controller side or the host side?

It becomes the host side (the side that outputs BT_REG_ON).

Hi @hi118 ,
I see that the RTS line is low when the controller is transmitting data. Are you referring to the intermittent peaks in the RTS waveform? Do you have a Digital Oscilloscope such as Salae to show a complete waveform?
