✅ 1. Check the Official Website

Go to Arad Connectivity’s official website and navigate to:

• • Products section: Each product page usually lists supported communication protocols (e.g., BLE, Bluetooth Mesh, Zigbee, etc.). Clicking on each protocol icon will also bring you to a related Tach-article. 
  • News or Technical Documentation: These often provide detailed specs and test reports (like this BLE Mesh article).

✅ 2. Download Technical Datasheets

Most Arad modules (like MN52H, MN53, etc.) have downloadable datasheets that specify:

• • Wireless protocols (e.g., BLE 5.0, BLE Mesh)
  • Supported profiles (GATT, GAP)
  • Certifications (FCC, CE, etc.)

✅ 3. Contact Support or Sales

For custom requirements or detailed protocol stacks (e.g., MQTT over BLE, proprietary mesh), email or call Arad’s technical team directly. They often provide:

• • SDK/firmware details
  • Integration support
  • Roadmaps for protocol upgrades

✅ 4. Look at Partner Ecosystems

Arad products integrate Nordic SoCs—these chips support multiple protocols, and Arad builds on their capabilities.
