Hi,
My development tool can connect to CY5677 usb dongle, but it can't work correctly when I pressed "pair" button to enter pairing flow(LE Secure Connections and Justwork authentication).
At first, CY5677 would send pairing request, then I send "pairing response" and followed by "pairing confirm(slave)". But CY5677 seems not to receive "pairing response" because CY5677 don't send "pairing random" and CySmsart pop up "AUTH_ERROR_AUTHENTICATION_TIMEOUT" a few seconds later.
I found it strange that after we sent "pairing response", my ble sniffer showed "crc error packets" from CY5677 at the next connection event.
However, I tried to set "SC bit(secure connection)" to 0 to request LE legacy pairing, it works fine!
I don't know why happened with CY5677 and how to pair with LE Secure Connections properly.
thanks!
