I would like to migrate from a BGX-based design and keep using Wireless Xpress. Is the Lyra (22) series pin-to-pin compatible with the BGX13 and/or BGX220?

Answer

The Lyra (22) series was introduced as a 100% software functional replacement for both BGX220 and BGX13 parts. We do support running the latest available Wireless Xpress v1.3.2XXX.X on it. Please find here the official Wireless Xpress release notes document.

From a pure hardware perspective, the BGX13 is not pin-to-pin compatible whereas the BGX220 is (except for the BOOT pin). See also: What is the difference between the Ezurio (formerly Laird Connectivity) and legacy Bluetooth Xpress (BGX) bootloader you provide for Lyra? 

Please make sure to carefully review our latest Lyra Series – Bluetooth Xpress (BGX) Migration Guide when migrating from a BGX-based module.
