BLE GATT Server functionality

I need to send a packet to a connected device as a server. In nRF Connect I do this without problems on the “server” tab. Is it possible to implement such a function in Garmin?

Also, the nordic samples in the SDK.

Also, see https://forums.garmin.com/developer/connect-iq/w/wiki/19/getting-started-with-connect-iq-ble-development as you need some nordic HW to test in the sim

Not everything you see with nRF Connect can be seen with CIQ BLE. Here's and app where you can see what CIQ BLE sees on a garmin device: https://apps.garmin.com/en-US/apps/9bcc8b66-8385-4afb-b93e-f69e01422284

Jim, I have no problems scanning, connecting to the device, or receiving notifications on Garmin. But I don’t know how to send a notification to device as a server, not a client, I don’t even know where to start. I don’t see any functionality in the Garmin API in creating a GATT server.

You can't with CIQ BLE You can only connect to something else. A sensor can't connect to the garmin

I found a post with a similar problem to mine, unfortunately there is no answer in it, how can I replace the functionality of the command notifyCharacteristicChanged. But it looks like there is really no solution at the moment... forums.garmin.com/.../ble-how-to-notify-characteristic-change-on-device
