can we make a mobile phone to act as a peripheral

[ps_anu]

hi... how to make a nordic app to act as a peripheral , i have read one post , in that they mentioned set up to be done in gap peripheral mode . how to do that

It depends on the phone - not all phones have the capability.

It probably also depends on the version of the phone's OS.

On Android (I know nothing about iOS), nRF Connect can act as a peripheral - if the phone supports it.

As Andy says, this has nothing to do with Nordic - you need the developer support resources for the mobile OS in question...

On a phone that can do it:

On a tablet that can not do it:

thank you so much , how can i connect  my phone to central , i hope i need to connect by using uuid and how to do that ?explain me

Again, that has nothing to do with Nordic.

You will have to study the developer documentation for whatever mobile OS(es) you're using - Android, iOS, or whatever.

eg,

https://developer.android.com/guide/topics/connectivity/bluetooth-le

https://developer.apple.com/bluetooth/

You will need to go to a mobile OS developer forum for mobile OS development support.

okay i got it peripheral part , what about central part which is our board nrf52840 if i enable gap peripheral mode in my mobile, it start to advertise how to get connection with nrf52840 central

[awneil]

The whole point of standards like Bluetooth is that this stuff does not depend on particular devices.

The nRF52840 as Central just sees Bluetooth packets;  it neither knows nor cares whether they come from a phone or a PC or another nRF chip - The behaviour is identical, as specified in the BLE standards.

 I  am working on multi link central example program , i have debugged the program in development kit . as per the program the device will scan for specific uuid , name  , so i have set the same uuid and name in nrf connect advertiser , it is not working . keep on scanning .

thanks in advance
