+# Magistrala CoAP Client for Zephyr
+
+This is a Zephyr RTOS application that connects to a Magistrala IoT platform using CoAP (Constrained Application Protocol) and sends telemetry data.
+
+## Features
+
+- WiFi connectivity with automatic IP address acquisition via DHCP
+- CoAP client with confirmable (CON) message support
+- UDP-based communication
+- Query parameter-based authentication
+- Simulated sensor data (temperature, humidity, battery level, LED state)
+- SenML JSON payload format
+- Automatic error handling
+- Configurable telemetry interval
+
+## Hardware Requirements
+
+- ESP32-S3 or compatible board with WiFi support
+- Zephyr RTOS support
 
 ## Requirements
 
-1. Mainflux broker details including: hostname, ThingID, Thing Credentials and Channel ID
+1. Magistrala broker details including: hostname, Domain ID, Client ID, Client Secret and Channel ID
 2. [Zephyr](https://www.zephyrproject.org/)
 
-## Configure
+## Configuration
+
+Edit `src/config.h` to configure your settings:
+
+### WiFi Configuration
+
+```c
+#define WIFI_SSID "your-wifi-ssid"
+#define WIFI_PSK "your-wifi-password"
+```
+
+### Magistrala Configuration
+
+```c
+#define MAGISTRALA_HOSTNAME "your-magistrala-instance.com"
+#define MAGISTRALA_COAP_PORT 5683
+#define DOMAIN_ID "your-domain-id"
+#define CLIENT_ID "your-client-id"
+#define CLIENT_SECRET "your-client-secret"
+#define CHANNEL_ID "your-channel-id"
+```
 
-1. Edit the [config file](include/config.h) with your broker details.
+### Application Configuration
+
+```c
+#define TELEMETRY_INTERVAL_SEC 30  // Telemetry send interval in seconds
+```
 
 ## Build
 
-The project can be built by utilising the make file within the target directory
+The project can be built by utilizing west within the target directory:
 
 ```bash
-west build -p always -b <your-board-name> mqtt
+west build -p always -b esp32s3_devkitc/esp32s3/procpu
 ```
 
 ## Flash
 
-Platform io generate a build directory with the fimware.bin within it. Use the make command to flash to board
+Use the west command to flash to board:
 
 ```bash
 west flash
 ```
+
+## Monitoring
+
+Monitor serial output:
+
+```bash
+west espressif monitor
+```
+
+## CoAP Resource Structure
+
+The client sends POST requests to:
+
+```text
+coap://{MAGISTRALA_HOSTNAME}:{MAGISTRALA_COAP_PORT}/m/{DOMAIN_ID}/c/{CHANNEL_ID}?auth={CLIENT_SECRET}
+```
+
+## Payload Format
+
+The client sends data in SenML JSON format:
+
+```json
+[
+  {
+    "bn": "esp32s3:",
+    "bt": 1761700000,
+    "bu": "Cel",
+    "bver": 5,
+    "n": "temperature",
+    "u": "Cel",
+    "v": 23.45
+  },
+  {
+    "n": "humidity",
+    "u": "%RH",
+    "v": 65.30
+  },
+  {
+    "n": "battery",
+    "u": "%",
+    "v": 85
+  },
+  {
+    "n": "led",
+    "vb": false
+  }
+]
+```
+
+## Authentication
+
+The client uses CoAP URI query parameter authentication:
+
+- Query parameter: `auth={CLIENT_SECRET}`
+
+## CoAP Features
+
+- CoAP Version 1
+- Confirmable (CON) message type
+- POST method for telemetry data
+- Token-based message correlation
+- Message ID for deduplication
+- Response timeout handling (5 seconds)
+
+## Error Handling
+
+- Automatic system reboot on WiFi connection failure
+- Automatic system reboot on DHCP timeout
+- Socket creation error handling
+- CoAP packet initialization and parsing error handling
+- Response timeout handling
+
+## Protocol Details
+
+- Transport: UDP (SOCK_DGRAM)
+- Default port: 5683
+- Message format: CoAP binary
+- Payload marker support
