is it possible to add support for nrf52 series #26

excited to find this, and now trying to remap it to s132, it it possible to add a officail support for nrf52 series?

alessandro-montanari commented 7 years ago

With s132 on nrf52 you can already have multi roles. Look at the ble_central_and_peripheral examples in the SDK. I took inspiration from the ble_app_hrs_rscs_relay example to scan and advertise concurrently.

@alessandro-montanari em.. so the multi roles advertise can also send a advertise without the random 0-10ms? we wanna to do the time-sync with advertisement

alessandro-montanari commented 7 years ago

@jasonbu no, the delay is there. I see your point.

jasonbu commented 7 years ago

@alessandro-montanari so it's possible to add this feature?

alessandro-montanari commented 7 years ago

@jasonbu I guess it's possible because you still have access to the radio interface directly, without the Softdevice

@alessandro-montanari I tried using nRF5_SDK_11.0.0_89a8197\examples\ble_peripheral\experimental_ble_app_multiactivity_beacon\hrs_advertiser this sample to nRF52 and it can be work allright now. but I found questions about the accuracy of the request latency. and trying to debug with it.

alessandro-montanari commented 7 years ago

@jasonbu I'm sorry but I'm not a developer of this library, I just used in the past with SDK v6 but I don't really know how it works internally. If you are more specific with your problem I'm sure there will be people able to help. Have you also tried on devzone.nordicsemi.com?

jasonbu commented 7 years ago

@alessandro-montanari I think this issue can be closed now, time accuracy is caused by HFCLKSRC, using RC got 3 thousandths mistake, using XTAL got fixed. it's all works now

alessandro-montanari commented 7 years ago

@jasonbu that's good. Just for curiosity can you explain what you were trying to do? I am interested in time-sync stuff :)

jasonbu commented 7 years ago

@alessandro-montanari i think it's not very difficult, put the local timestamp on the adv payload, and remove the random delay. we are trying to do this, and test if it is a good solution.

ver similar with https://github.com/nordic-auko/nRF5-ble-timesync-demo but not special RX within the HOST
