Hi.
Developing PAwR in project, I have some Question.
before Asking, My Project Structure is below.
1 Gateway (Advertiser) - Node1 (Scanner)
- Node2 (Scanner)
- Node3 (Scanner) ... More
Most of all is Done, but Some Encryption is Question.
1. my understanding is correct under below?
EAD in Ble 5.4, for Encryption, need Encrypted Data Key Material characteristic, and it's characteristic require Encrypted and authenticated permission.
for this permission, security Mode need mode1, level 3. and for that, it need OOB.
2. if question 1 is correct, my project can not use OOB. so for Encrypt, need app level encryption?
3. I Saw ESL Example, the project is seem to use EAD, the EAD and Question 1 EAD is Not same?
4. in ESL Service , I think for EAD use AP Sync Key Material, ESL Response Key Material. What difference this and Encrypted Data Key Material characteristic?
in ESL no need OOB?
5. I also Saw ESL Example video, ( Getting started with Bluetooth Electronic Shelf Labels (ESL) and Periodic Advertising with Responses (PAwR) )
There was nothing about how to do bonded. how satisfy AP, response key material characteristic permission?
thank you
