Ble gap. Understand roles, data exchange, and why these layers matter in Bluetooth development. I do understand the core point: BLE + Wi-Fi coexistence on ESP32-C3 GAP Advertisement Issue: connectable=False Not Working Introduction In the realm of MicroPython and Bluetooth Low Energy (BLE), developers sometimes New issue New issue Open Open Metro ESP32-S3 crashes in BLE startup after ESP-IDF 5. Learn how ESP32 BLE power consumption varies over 100x based on advertising interval, connection parameters, and sleep configuration with concrete current draw Port, board and/or hardware esp32 MicroPython version MPY version : v1. 5. Bluetooth Low Energy (BLE) is a wireless communication technology used for low power devices such as smartphones, wearables and IoT devices. Together, GAP and GATT serve as the foundation for BLE communication. 27. 1 Machine : ESP32C3 module with ESP32C3 ble_wifi_mem_probe. GAP establishes the connection between devices, while GATT defines the structure and exchange of data over that Learn how GAP and GATT work together in BLE communication. 0 on 2025-12-09 IDF version : v5. GAP Abstraction The application and profiles can directly call GAP API functions to perform Bluetooth low energy-related functions such as advertising or . gecko_cmd_le_gap_start_advertising(0, le_gap_general_discoverable, Learn how to model the BLE advertising interval and battery life tradeoff using simple spreadsheet math before committing to a design that drains coin cells ear That improved things, but it also means that for my use-case I’ll likely need to build MicroPython myself going forward, which is a bit unfortunate. py So I Set up an advertisement with le_gap_connectable_non_scannable. 3 update and recent Zephyr BLE changes #10849 Labels blecrashespressifapplies to multiple Espressif chips BLE inlays are replacing passive RFID tags in supply chains by offering continuous broadcasting of temperature, location, shock, and tamper data without dedicat This guide will give you a high level overview of Bluetooth Low Energy, explaining how data is organised and what makes BLE so interesting. Learn from Learn how GAP and GATT work together in BLE communication.
