### 2/5 — Difficulty connecting

*2023-08-23*

When using an iPhone 13Pro, and connecting to a KH140f, it can take upto 10 scans to connect over Bluetooth (if it connects at all). The app works well once connected. When you open another of Juncteks apps, (KG for example) it connects immediately on the first try, but gives a wrong model error once connected (as it should). This appears to be a Bluetooth issue, as it connects fine with the other app. I have a video recorded detailing the issue. Please reach out to me to address this. Thanks!
