https://devzone.nordicsemi.com/f/nordic-q-a/110134/not-able-to-determine-ble-encryption-after-enabling-from-nrf-sdksHello All, I am using nrf52805M from fanstel (LINK) , and code which is based on nrf sdk softdevice S112. Things works great normally, but in order to satisfy the cyber security requirements I am enabling BLE encryption and MIMA protection using belowen-USTelligent Community 13Tue, 23 Apr 2024 04:58:01 GMThttps://devzone.nordicsemi.com/thread/480086?ContentTypeID=1Tue, 23 Apr 2024 04:58:01 GMT137ad170-7792-4731-bb38-c0d22fbe4515:324aa380-9fe7-4489-939d-29f636cc0340vaibhavkambli<p>&nbsp;I am able to achieve encryption using BMS module</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/478242?ContentTypeID=1Thu, 11 Apr 2024 09:22:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:04130a05-3214-4b96-892b-5283d3635e08Einar Thorsrud<p>Hi,</p> <p>What you have shown here is that you have chagned the security requieremetns for some characteristics.&nbsp;That only affect these characteristics though, and does not change the security level of the link. As you got the error you got, that indicate that you have not paired or bonded with high enough security (using MITM)?</p> <p>PS: If you are starting development now you should consider the nRF Connect SDK.
