FAE Expert Insights
"CH582 offers excellent value for BLE applications. The BLE 5.3 long-range mode provides 2-4x range improvement over BLE 4.2, making it ideal for industrial IoT. The integrated RISC-V core eliminates need for separate host MCU. Power consumption is competitive with Nordic and Silicon Labs alternatives. The SDK includes comprehensive BLE stack and examples. One limitation: the RISC-V core is not as fast as Cortex-M4, but sufficient for most BLE applications."

Frequently Asked Questions
What is the range of CH582 in long-range mode?
In BLE 5.3 long-range mode (Coded PHY, 125kbps or 500kbps), CH582 can achieve 2-4x range compared to standard 1Mbps mode. Actual range depends on environment, antenna design, and obstacles. Typical indoor range is 50-100m, outdoor line-of-sight can exceed 300m. Use with appropriate antenna for best performance.
Use long-range mode for maximum distance. Standard mode for higher data rates. Contact our FAE team for antenna design.
