ESP32S3, How to close flow control of USB CDC
Posted: Fri May 03, 2024 8:14 am
Hi Team,
Is there any way to close flow control of USB CDC?
When dtr = 0. CDC CONNECTED. USB CDC write OK.
When dtr = 1. CDC DISCONNECTED. USB CDC write failed. Host can't get response from the device.
Ken.
16:09:32.971 -> CDC LINE STATE: dtr: 0, rts: 1
16:09:33.910 -> CDC CONNECTED
16:09:33.910 -> CDC LINE STATE: dtr: 1, rts: 1
16:09:34.988 -> CDC DISCONNECTED
Hardware: ESP32-S3-DevKitC-1
