nRF8001 Sleep mode Pairing

[Florent Muret]

Hi Support team,

I am looking to replace my BLE chip by a nRF8001. I am currently using a DA14580 (Dialog Semiconductor), in  Beacon mode or pairing mode. I saw that the nRF8001 cannot works in Beacon, so I am wondering about pairing mode : is that possible to connect/pair the BLE chip to a device (smartphone), to do advertising, and then put the nRF8001 in sleep mode and still keep the connection between the phone and the BLE chip in the same time ? Then I will be able to trigger an interupt, go out of the nRF8001 sleep mode and do another advertising without needed to connect the device again. Is this behavior possible (as I would like to use pairing mode with the smallest amount of current as possible).

Thanks by advance for your help,

Best regards,

Florent

Ok thanks for thoses links. I guess you can have pre-made code in C as well on nRFgo studio as well ? 

[David Edwin]

you can but typically it is preferable to just use the services.h which contains the #defines and not use the generated C code.

You mean the services.h auto generated by nRFgo studio ? 

And so do you have an idea of the speed of the data transmission while using pairing or beacon  ?

[David Edwin]

While advertising (paring/paired) the data transmission is at 20 ms per interval and you need to replace the data being sent every advertising event. The data available for transmission per advertising event using the Service Data AD type is approximately 20 bytes.

When running the broadcasting using advertising (ACI broadcast) the interval is 100ms.

Does this answer your question ?
