implementing custom service

[Srikara]

product details:

nRF52840 custom board

nRFConnectSDK 2.2.0

we want to implement custom service interacting with the Android app.

Where we will receive on command from Android app and we will do some processing and sending the data back to the android app.

For this what and all we need to do.

for ex: service

what characteristics and what descriptors are needed and their properties.

All we need to know is how to write custom service and for our requirement what we need to add.

Hi,

Here in Norway we have had the Easter holidays, causing the delay in the answer. But we are all back in office now.

To learn how to add new services to a BLE device, I recommend our Bluetooth Low Energy Fundamentals guide.

Hi

Sorry i was completely occupied with multiple objects. Did not get time to look into this.

Got some breathing time. This we are planing initially as POC.

THe requirement is: Custom service where

1.From APP to NRF initially one request comes to send the data

2.As the request comes the data will be sent from NRF to Android App.

3.One main thing is this service and characteristics should run parallelly with the SMP service which as part of other PRIVATE case is handled.

SO DFU and this custom service should work parallelly.

For Both to work, how two services need to be implemented and what should be the custom service characteristics.

Did you look at the course I linked to?

Were you able to add a custom service?

Hi

Sorry for the late response. I was on leave for last 2weeks. I was able to understand how to add custom service. But Now how to add the two services and in the advertisemnet packet i may need to have both DFU service and the custom service as the app will intiate the connection if the custom service is implemented. But for the FW upgrade if we are using nRF Device manager app it will shortlist by the DFU service right? ot is there any other way we can do DFU over BLE.: devzone.nordicsemi.com/.../ncs-dfu

Yes, but in the settings for the app you can choose to list all devices instead, and then choose device, even if it is listing the DFU service or not.

Does that answer your question?

Ok Ok got it. You are saying in the settings we can select to see all the device instead of running with SMP server.

Will test that, may not be now as busy in other project/issues. \

Thank you.

Yes.

And if you make your own phone app later you can make that phone app sort for your UUID specifically
