Again post "Bluetooth device development + associated iOS code"

Hi all, Goal is to improve upon a device (bluetooth recording device) and associated iOS code that will record conversations, save them on the device, and sync to an iOS based app. The current device has two issues and one improvement needed. THIS IS THE PROJECT. 1) Issue: Conversations saved to the SD card do not sync quickly to the iOS App 2) Issue: Multiple conversations saved on the SD card sometimes do not sync to the iOS App and crash 3) Improvement: Currently, recording starts when the user press a button on the device. We want the enable speech recognition recording. So when the user says "Device record", we want the recording to start from then. Current device: Specifications attached .hex file will be shared
