v1.6.1 Prescription Saving, 16-channels, and Biquad Filterabanks
In this release, we added a new example: 05-FullSystems\WDRC_NBand_Stereo_Earpiece_Prescrip_wApp. This example illustrates four new capabilities not included in earlier releases:
- Up to 16 channels of WDRC per ear (and this example processes the left and right ear independently!)
- For the filterbank, you can use either FIR filters or an IIR (Biquad) filters
- You can save the filtering and WDRC prescriptions for each ear to the Tympan's on-board SD card
- This communication to the Bluetooth module is increased to 115200 for this example [* see warning below]
This is the largest, most capable hearing aid example that we have ever made. And, all of the functionality can be adjusted via the TympanRemote App (Android, iOS). I'm super excited about this newest and greatest "Full System". I look forward to getting feedback on what improvements are needed!
[* Warning: The increased communication speed enables the Tympan to transfer the setup data to the mobile app more quickly. The higher speed is helpful because the Tympan and the App need to exchange a lot of settings. The higher speed makes your experience better. But, we have found that iOS (Apple) devices do not respond well to the high-speed communication setting. So, if you use iOS and you want to use this example, you will have to find and comment out the line ble.setUseFasterBaudRateUponBegin(true);. The data transfer will be slower, but it will then work with iOS.]
