Fix a bug: sample loss in Android app when retrieving data via BLE

I'm developing an Android app which retrieves data via BLE from a device in real-time. As stated in the device's datasheet, BLE uses a 20-ms connection interval. Twenty user-data bytes (which is equal to 2- samples for each channel and 2-bytes running counter) are sent in GATT notifications. Data from the device is ping-pong buffered and up to six BLE-notification packets are sent every 14 ms based on an OSAL timer. The sample rate is set as 160 samples/sec. Each sample is 3 bytes and is sending 3 channels. Each notification packet consists of 20 bytes containing the following: Measurement Sample 1 (Raw ADC data): - Channel1 (3 bytes) - Channel2 (3 bytes) - Channel3 (3 bytes) Measurement Sample 2 (Raw ADC data): - Channel1 (3 bytes) - Channel2 (3 bytes) - Channel3 (3 bytes) Afterwards I plot this data, but it looks like that I am only getting a sample rate around 105, while there should be 160 samples/sec. It just looks like some samples are missing looking from the signal. I would like you to fix the bug. Here's a code that I use: [login to view URL]
