Multiple devices trying to ABP

Hallo seniors and anyone help me please,
If I have several devices (example 100 devices) trying to use ABP method.

  1. How often and how long does the activation take for each device, because it will takes time and consider about the efficiency and security part.
  2. Is physical access to device necessary (e.g press button)?
  3. Do all devices consider the security part use the same key?
  4. When does ABP needs to be re-initialized?

Thank you very much :grinning:

Have you read the LoRaWAN specification on ABP? That might be a good start to understand how ABP works and what limitations there are :slight_smile:

As @brocaar has mentioned, this is a clear instance of you needing to RTFM.

However, I just want to point out that the answers to your questions are highly dependent on the device you are deploying.
