scanning and decryption of data

[Naralasetty Praneeth]

I had two nRF52832 where one broadcasts with encrypted data of advertising beacon info and another nRF52832 should only scan without connecting and should decrypt the data of beacon which is broadcasting.

for that what should i do?

please give me any sample code if available

Hi @Simon

ok with the decryption part but now my problem is mainly about the Scanning part

I need to scan the beacon's MAC address,UUID,Major,Minor,battery level etc the scanner should only scan beacons it should not get connected after detecting. 

Thank you

The links I provided you are not about connection. When connected the Peer Manger handles the encryption/decryption for you, but if you want to encrypt/decrypt the advertsing data you need to perform it yourself, and the links provided will show you how.

Take a look at the code provided in this thread, which shows how to encrypt and decrypt data.

Best regards,
