What specific steps can I take to minimize interference and optimize the pairing stability between my Garmin Edge 530 and my power meter, particularly in high-traffic environments or when riding in close proximity to other cyclists devices? Are there any firmware updates, device settings, or physical placement tweaks that can significantly reduce dropped Connections and improve the overall reliability of this critical data connection? Additionally, what role do factors such as cadence sensor placement, battery life, and signal strength play in maintaining a stable connection, and are there any best practices for troubleshooting and resolving common pairing issues?
