Soft Manager? Do you mean Device Manager? Please see this question. If you have more questions, I suggest you add them separately. I would also appreciate if you could accept my answer by clicking the grey circle with a check mark, if you feel it answers your question.

First thank you very much, your answer is very useful. but I'm still confused what the Nordic51822 should do when bonding. I found the Bond Manager had been changed to Soft Manager since S110 V7.0. Is there any applicantion note I can reference ?

The Bluetooth Specification 4.1 explains bonding, see Vol. 3, Part C, Section 9.4 and Part H, Section 2.4.1. There is a couple of BLE books available, this and this. In addition, there are some training videos here.

On Android API level 19 and above I believe you can use public boolean createBond (), see this, but I haven't tested this myself.

On lower API levels bonding must be triggered by accesing a characteristic that requires the link to be encrypted. The link requirement can be set with:

BLE_GAP_CONN_SEC_MODE_SET_ENC_NO_MITM(&attr_md.read_perm);
BLE_GAP_CONN_SEC_MODE_SET_ENC_NO_MITM(&attr_md.write_perm);

This corresponds to

Security Mode 1 Level 2: Encrypted link required, MITM protection not necessary.

See the Bluetooth Specification 4.1, Vol. 3, Part C, Section 10.2 for more information.

The Glucose Meter example in our SDK uses BLE_GAP_CONN_SEC_MODE_SET_ENC_NO_MITM(&attr_md.read_perm);, please examine glucose_feature_char_add(...).
