ESP32 Arduino 2.0.0 release adds ESP32-C3 and ESP32-S2 support

As just noted in my article about LILYGO T-32C3 module, the ESP32 Arduino 2.0.0 release happened a few days ago adding ESP32-C3 and ESP32-S2 support to the Arduino IDE. But the news probably warrants its own post and it is a major release of the Arduino code for ESP32 that also includes other new features and changes namely: Upload over USB CDC. Support for the KSZ8081 Ethernet PHY. LittleFS update for partition label and multiple partitions. Added support for RainMaker. BLE 5 features for ESP32-C3 (ESP32-S3 ready). ESPTOOL update. Added 802.11mc WiFi RTT FTM (Fine Time Measurement) support. Online Documentation added (somehow it requires a login to Readthedocs). USB MSC (Mass Storage) and HID support (ESP32-S2 only). UART refactoring (SerialHardware). New examples, boards added, bugs fixed. You can find a more detailed changelog, including the exact files changes in the source code, on Github. If we want to give it […]

Compulab WILD WiFi Router Supports WiFi RTT (802.11mc) Location

When Google released the first Android P preview back in March, one interesting new feature was indoor positioning through 802.11mc WiFi aka. WiFi RTT (Round Trip-Time). That looks promising so I started to look for 802.11mc capable routers, and all I could find were some Intel cards and Marvell chips with WiFi RTT, but not actual products. Since then Android 9 has been formally released, and today I’ve learned that Compulab launched a WiFi RTT capable router that will work with Android 9.0 phones. Meet Compulab WILD. Compulab WILD WiFi RTT router specifications: SoC (from a choice among three) Intel Atom x7-E3950 quad core processor @ 1.6 / 2.0 GHz with 18 EU HD graphics; 12W TDP Intel Atom x5-E3930 dual core processor @ 1.3 / 1.8 GHz with 12 EU HD graphics; 6.5W TDP Intel Celeron J3455 quad core processor @ 1.5 / 2.2 GHz with 12 EU HD […]
