esb "realtime" - timeslots - nrf51 example

[Martin]

Hi

can ESB be considered RealTime transfer as soon as it has it's timeslot?

Outline of use-case:

• Device advertises existenace on BLE
• If there is data waiting for this device, it would be notified e.g. by an attr-read
• the device turns on radio for ESB, central connects via pipe and pushes data to device.
• disconnect, reset device

Is this mixed mode scenario possible with the SD130 ?

Thanks

This scenario is possible with S130. To send data to the device (notification or attr-read) you have to be connected, so you would have to connect after advertising.

If ESB is “realtime” depends on what you call “realtime”. ESB may be the fastest way to send data as soon as you are in a timeslot or have full control over the radio.

Update 2016.08.09: Here is a project that uses esb in timeslot: ble_app_uart - ESB_Timeslot.zip

Can you hint me to an example project for SDK11 which works? I was not able to make this scenario work for the last 3 days. Also because of this problem: other question
