Dear ESB technical specialist
Regarding the ESB function of nRf52833.
The datasheet explains BLE function, but there is no explanation about ESB.
For this reason, I assumed that ESB was the protocol used by the BLE HW block in the chip. However, this understanding may be incorrect.
I am investigating a question from a customer regarding product export control in Japan, and I am having trouble because there are some unclear points about the technical details.
Could you please answer the following basic questions?
(1) Both BLE and ESB are communication functions, but they are different understandings of communication methods.
Is this understanding, correct?
(2) BLE uses frequency hopping, but ESB uses fixed frequencies (Not uses frequency hopping). Is this understanding, correct?
(3) In BLE, encryption is used during pairing. Is this understanding, correct?
It is not normally used in ESB, but can it be used?
If it is used, which encryption is used, HW or SW?
When using encryption with ESB, what kind of encryption can be used?
Sorry for the inconvenience, but please reply.
Best Regards
Sato
