HI,

I want to implement the software security to NRF52832 such a that no one should be able to read the memory or tap the data during Bluetooth communication.

Hi Manoj

There are multiple ways to ensure the safety of your data during Bluetooth communication. I suggest you check out the ble_app_hrs and ble_app_hrs_c examples, which uses the LESC module and bonding to keep the data safe.

Best regards,

Simon

Hi

I linked to the LESC module in my last reply with this link https://infocenter.nordicsemi.com/index.jsp?topic=%2Fsdk_nrf5_v16.0.0%2Fgroup__nrf__ble__lesc.html&resultof=%22%4c%45%53%43%22%20%22%6c%65%73%63%22%20. You can also check out this thread from the official Bluetooth blog: https://www.bluetooth.com/blog/bluetooth-pairing-part-4/

I your last reply  https://infocenter.nordicsemi.com/index.jsp?topic=%2Fsdk_nrf5_v16.0.0%2Fgroup__nrf__ble__lesc.html&resultof=%22%4c%45%53%43%22%20%22%6c%65%73%63%22%20. it just the information of the statements used regarding LESC. It doesn't tells how it works.

One more thing, is LESC module is only for Bluetooth 4.1. because in the blog https://www.bluetooth.com/blog/bluetooth-pairing-part-4/ it is mentioned liked that.
