Dear,

I would like to ask for the difference between APP_EVT_TYPEC_ATTACH and APP_EVT_CONNECT.

If I want to detect TypeCCable plug in NB, which event should I detect?

Thank you.

Hello,

APP_EVT_TYPEC_ATTACH signifies Type C attach event i.e when the terminations Rp or Rd is detected (detecting a port partner is connected).

APP_EVT_CONNECT signifies Type - C connect detected i.e. the PD contract is established with the port partner.

Best Regards,

Yatheesh

Dear Kandlagunta,

I made a dock and used the CYPD4236-40LQXI_dock sample code.

Thank you.
