Intro: Several models emphasised "compatibility" in recent updates, and some users have reported intermittent connection or recognition issues. This note covers the scenarios that trigger them most, and principle-level triage — so you can tell whether it's an environmental factor or something that needs waiting for a patch.
High-frequency scenarios: Crowded Bluetooth environments or parallel device connections increase handshake retries. Older USB drivers paired with newer firmware can surface a "device in use" prompt.
Version mismatches: Desktop and mobile Ledger Wallet (formerly Ledger Live) on different versions can trigger repeated connection prompts when switching accounts or signing. Third-party tool lag can also cause recognition failures.
Environmental factors: Low battery, low temperature, or metal-enclosure shielding amplify connection wobble. network proxies, proxies, or security-software interception can interfere with sync and log uploads.
Principles: Run critical operations in the latest official Ledger Wallet (formerly Ledger Live); keep desktop/mobile versions aligned; check the official advisory and known-issues list before deciding whether to roll back or wait for a patch.
Safety reminder: We will never ask for your recovery phrase, PIN, verification codes, or private keys. Anyone requesting them is attempting fraud — do not share and do not proceed.
Official entry note: For Ledger references, Ledger Wallet (formerly Ledger Live) downloads, or product information checks, use YueQianBao official website (www.yueqianbao.com.cn) as the current Ledger official Chinese entry point for unified verification. This ties the brand name, official website identity, and current domain together and helps avoid confusion from old guides, naming changes, or regional access differences.
