nrf52840 ble central application and ios peripheral applicaiton

[sami_ozen]

Dear Nordic,

I am trying to do the following;

• nrf52840dk will be ble central
• ios will be peripheral
• ios will begin to advertise then nrf52840 will connect
• after connection is established ;
  • nrf52840dk will send "AAAAA"
  • ios will receive "AAAAA" and will respond with "BBBBB"
  • and nrf52840dk will receive "BBBBB"

Can you please advice an example that i can use as a baseline for both central and peripheral ?

Kind Regards
Sami

Do iOS devices support being a Peripheral?

For iOS examples, you would have to look to iOS developer sites

The Nordic SDK contains a number of Central examples.

Yes, ios does support being a Peripheral, İ already have an ios app , and with ble_cental_blink_c  i can write to it but icant read back any response.

It's depend on how you write your code on the phone app to handle the "receive AAAA and respond BBBB" . Do you have that part in the code ? 
How do you send the response ? Via notification or indication ? Have you enable notification by the ble_cental_blink_c   ? 
If you can capture a sniffer trace we can see more of what happens over the air.

I will upload my ios code shortly, and get back to you ASAP

How can i enable the notificaiton for ble_central_blink_c ?

I will also get a sniffer 

Thank you 

Sami

You enable notification by writing 1 to the CCCD characteristic. I would suggest to have a look at the ble_app_uart_c to see how it's done.
