Bluetooth Low Energy 5.1 MESH SoC

OverviewFeaturesRequest Datasheet
The Bluetooth Low Energy (BLE) 5.1 MESH chip with internal Flash and audio support combines the features and functions needed for all 2.4GHz IoT standards. It supports multiple standards including Bluetooth Low Energy (BLE) 5.1 with up to 8 antenna indoor positioning support, Bluetooth Low Energy (BLE) Mesh standards. The embedded FLASH enables dynamic stack and profile configuration, and the final end product functionality is configurable via software, providing ultimate flexibility. The SoC also has hardware OTA upgrades support and multiple boot switching, allowing convenient product feature roll outs and upgrades. The MESH SoC supports single-channel analog mic or dual-channel digital microphone, and stereo audio output with enhanced voice performance for voice search and other such applications. The MESH SoC have passed ETSI EN 300 328 and EN 300 440 Class 2 (Europe), FCC CFR47 Part 15 (US) and ARIB STD-T66 (Japan) certification. Bluetooth-Low-Energy-5.1-MESH-SoC-supplier-in-europe
