Detailed Description

BLE example showing a minimal custom service with READ + WRITE characteristics.

This example demonstrates how to implement a custom service using:

• a .gatt profile (compiled into app_profile.h)
• AttributeServer to locate services/characteristics by UUID
• Characteristic::EventHandler to react to reads and writes

---

GATT layout

Service UUID: 0xFFE0

• PublicValue (UUID 0xFFE1): READ (dynamic)
• WriteValue (UUID 0xFFE2): WRITE / WRITE_WITHOUT_RESPONSE (dynamic)

---

How to test (nRF Connect / LightBlue)

1) Connect to "c7222-rw-demo" 2) Read "PublicValue" -> returns the current value 3) Write any bytes to "WriteValue" 4) Read "PublicValue" again -> it becomes whatever you wrote
