I'm reaching out regarding an issue I'm experiencing with my BMS for the lithium iron phosphate batteries I have. I'm trying to connect it to the Smart BMS app on my phone via Bluetooth, but unfortunately, the app doesn't seem to launch anymore. I'm unable to diagnose the issue, and it's been quite frustrating trying to troubleshoot this on my own. I would greatly appreciate any assistance you can provide to help me resolve this connection problem. If there are specific steps or tips that you recommend for troubleshooting or resetting the connection, please let me know. Thank you for your support!
