STM32MP135F-DK Discovery STMicroelectronics STM32MP13micro-processor is based on Arm Cortex-A7, and a lot of work went into not only adding support for it in Zephyr—PR#87687—but basically also introducing Zep
Instead of using an ESP32 and a separated LoRa transceiver module, there are ESP32 development boards with a LoRa chip and an OLED built-in, which makes wiring much simpler. If you have one of those boards, you can follow:TTGO LoRa32 SX1276 OLED Board: Getting Started with Arduino IDE....
The ESP32 adds anextra CPU core, fasterWi-Fi,more GPIOs, and supportsBluetooth 4.2andBluetooth low energy. Additionally, the ESP32 comes withtouch-sensitive pinsthat can be used towake up the ESP32 from deep sleep, andbuilt-in hall effect sensor. Both boards are cheap, but the ESP32 co...
The ESP32 comes not only with Wi-Fi but also with Bluetooth and Bluetooth Low Energy (BLE). This post is a quick introduction to BLE with the ESP32. First, we’ll explore what’s BLE and what it can be used for, and then we’ll take a look at some examples with the ESP32 usin...
