I'm currently in the process of setting up a battery management system, but I'm encountering issues with the Bluetooth connectivity. The connection to my iPhone keeps timing out after roughly 10 seconds, which is preventing me from completing the initial configuration.

Additionally, if there are any firmware updates or specific settings that I should be aware of, please share those as well. Ensuring a stable connection is crucial for me to proceed with the setup, so your prompt support on this matter would be greatly beneficial. Looking forward to your assistance!
