Hello,

I'm working on CYW20719, I'm using Bluetooth as with SSP profile and NVRAM to save paired host (a windows PC in my case), It works well, even after power on/off the device remember the host key and allow connexion.

But after doing some modifications in the application and downloading back the firmware, reading in NVRAM seems to be impossible. I have to impair the device from Windows and pair it again. It is an impossible workflow will application development, is there a way to get rid of it ?

Best regards

Hello,

The NVRAM data will overwrite while programming the device. Thus bonding data will be lost.

Regards!
