Our product use CYW20704UA2 for BT4.2 HOST application.
But refer Qualification and Certification – KBA222020 CYW20732/20736/20737/20706/20707 Qualification and Certification – KBA222020 & find at Launch Studio - Listing Search
When we provide QDID#104467 for certification, LAB mention this QDID is BT5.0 not BT4.2.
Then we provide another QDID#72771 ,LAB also mention this expired over 3 years.
Have any wrong for the communication?
Now I can't find suitable QDID for certification.
Yes the QDID 72771 is expired, we have new QDID 115853 registered for WICED BT stack which is BT5.0 compliant.
Also, please note that CYW20704 is not a broad-market chip. Please contact your local cypress point of contact for more support regarding this.
