How to adjust carrier frequency accuracy

Hello Cypress community,

I hope you're all doing well. I'm currently working on a project involving CY8C4245-AXI and CY8C4246LTI-M445 controllers for a Touch Switch application, and I'd like to discuss the implementation of an Over-The-Air (OTA) update feature for these controllers. I believe this feature will greatly enhance the flexibility and long-term viability of my project.

I'm reaching out to the Cypress community to gather insights, best practices, and potential solutions for implementing OTA updates on the CY8C4245-AXI and CY8C4246LTI-M445 controllers. If you have experience with similar projects or have expertise in OTA update implementation, your input would be greatly appreciated.

Thanks and Regards,

Pankaj

Where can I find firmware and instructions to update my CYBLE-212006-01?

CYBLE-212006-01 is having issues connecting to devices with Bluetooth versions 5.1 and 5.2.

CYBLE-212006-01 is able to connect to devices with Bluetooth version 5.0.

I understand this module is a PSoC 4 BLE based device that only supports Bluetooth 4.2. Bluetooth specification states that all Bluetooth Versions shall be backwards compatible. I understand there are optional features in Bluetooth 5.0 and above that may not be compatible with a Bluetooth 4.2 device. Those optional features should NOT prevent a simple connection and basic communication.
