What is need of addition authentication in case of #BluetoothMesh if ECDH public key exchanged over OOB ?
#bluetoothmesh
Hi, If #BluetoothMesh DEVICE ECDH-public key (oob public key) is exchanged over OOB channel then what is further need of authentication using input-OOB or output-OOB or static-OOB ? Thanks,

Hi, I think we can do OOB pairing, even if Device doesn't have display to share Passkey with user App. 1. Create ECDH public-private key pair (only once in Device life) 2. Read ECDH-Public key via Dev

Hi Vakul, Thanks for reply !! No, APP can't differentiate between Genuine & Fake device. And Yes, user by mistake can connect with his neighbor/attacker Device. solution - 1) APP will check RSSI signa

Driver API conference calls
Hi Carles, I would like to inform you that #nRF52 i2c driver is still buggy because we could read but can't write using it on I2C devices. I've tested it using AT24Cxx EEPROM. Thanks, vikrant8051
