I have a wearable running Android OS. I want to make it possible to pair mobile phones(Android+iOS) via Bluetooth and see all the notifications over MAP. Could somebody help me on what I need to implement on my wearable to achieve this? From what I understood MAP services are enabled by default with modern Android and iOS phones. I believe this is the same technology used by connected devices in smart homes and car stereo. Should the goal be to implement a GATT client?
You can take Android native MAP client MAP client. It uses OBEX (Rfcomm connection). When notifications are enabled your MNS server will receive them. But I am not sure if such solution will work if your OS already has a working MAP client.
