Hi,

Power SDK doesn't explicitly identify SDP. According to BC protocol primary detection separates SDP from CDP/DCP. Please refer to bc_fsm_sink_primary_charger_detect() function where non CDP/DCP port is directly treated as "Type-C only source connected"

Best regards,
Pranava

Dear Sir

What we need is detailed reasons why the Power SDK doesn't explicitly identify SDP.

Hi,
Apologies for delay in response.

All other legacy charging protocols begin with DCP/CDP detection initially. SDP state detection is not explicitly implemented and is directly considered as Type-C only Source.
