nRF in V2V ?

Hi,

Can we use nRF in vehicle to vehicle communication V2V ? And how max nodes can we have ? As I know, the nRF don't need authentication when we send data, is it true ?

  • Hi, you seems to be mixing chip vendor/family (=nRF), application (V2V) and protocol (=max nodes, authentication). These things are pretty independent: yes, Nordic nRF51/52 family chips probably can be used in "vehicle to vehicle" (or M2M in general;) communication, specific topology and security largely depends on protocol stack and profile/application you design on top of it. If you talk about BLE then latest Nordic stack on nRF52 support up to 20 simultaneous connections, however there are other options like open source stacks (some seems to support 32 concurrent connections or even more) or some non-BLE protocols/technologies where some might be running with hundreds/thousands of nodes in the network (of course with much lower bandwidth then BLE). Similar answer to "authentication: question. Could you maybe provide much more details to your questions so we can give you better answer?

    (also note that if you need chip with automotive-grade spec - e.g. temperature ranges, vibrations' endurance etc. - then Nordic might have no suitable offer for you today...)
