Feb 27, 2023 · WiFi BLE coexistence adjustment for BLE disconnect Postby esp32person » Mon Apr 14, 2025 11:33 pm Hi, Anyone know how to adjust the WiFi BLE coexistence % (or priority ) adjustment? 1. You have to remember its shared radio and you have to give some time to wifi and ble to operate. I'm still studying the BLE Mesh architecture, it's a pretty steep learning curve and confusing, but as far as I understand so far Sep 7, 2022 · I am trying to see if it is possible to setup a BLE mesh and wifi coexistence on an ESP32-c3-M1 dev kit. So I am slightly confident that it has something to do with radio sharing between BLE and Wifi. Espressif is a global high-tech leader in wireless communication, IoT, AI SoCs, software, and solutions, for a smarter and greener future. There are two parts: a. I heard that there is CONFIG_ESP_COEX_SW_COEXIST_ENABLE Enable option in menuconfig. In such scenarios, ESP32-S3 employs the time Jan 16, 2024 · As the document say, for most coexistence cases, ESP32-C3 will switch the coexistence status automatically without calling API. When I remove this, most of the espnow transmissions get lost. My suggestion is to start with very simple app with 2 tasks, 1 for wifi and 1 for ble. Under such circumstances, ESP32 uses the me-division mul plexing method to receive and transmit packets. To ensure better communication performance of Wi-Fi and Bluetooth in the case of coexistence, run the task of the Wi-Fi protocol stack, the task of the Bluetooth Controller and Host protocol stack on different CPUs. Is this assumption correct? What effect does this have on the coexistence of WiFi on the ESP32? How is that problem of the radio being occuppied by BLE or WiFi Project template is designed to provide a starting point for building projects that require both WiFi and BLE functionality on the ESP32 microcontroller.

In such scenarios, ESP32-C3 employs the time Jun 1, 2022 · The ESP32 Sparkfun Thing was also tested but did work successful as a single board BLE to WiFi bridge A number of other projects use a two board BLE to WiFi bridge, Simple WiFi to Bluetooth Low Energy (BLE) Bridge, BLE Room Temperature controlled Heater with Timer Switch and BLE Low Power Indoor/Outdoor Weather Station. 4. In the wifi + espnow setup, esp_wifi_set_ps is set to WIFI_PS_NONE. Wifi is OK (pings works), but scanning is very poor. I changed it for BLE scanning (like in 'blecent' example) because I need to have connection with wifi and scanning BLE advertiser (my other BLE device - sensor). I use ESP32-C3, so according to Oct 17, 2024 · In case of wireless coexistence of BLE connection + WiFi STA mode, part of BLE connection events (15ms interval) will be pre-empted by Wi-Fi activities, however, the SupervisionTimeout is as long as 6s, which allows at most 400 chances for two devices to communicate and restore synchronization. There is BLE advertising implemented and wifi pings. May 23, 2025 · Many modern IoT applications require ESP32 devices to handle multiple wireless communication tasks simultaneously. In the configuration on the Arduino IDE, I Jan 28, 2021 · I tried 'bleprph_wifi_coex' example. 4 GHz ISM band RF module, which is shared by Bluetooth (BT & BLE) and Wi-Fi, so Bluetooth can’t receive or transmit data while Wi-Fi is receiving or transmi ng data and vice versa. You can use this template as a starting point for your own ESP32 projects that require both WiFi and BLE functionality. In such scenarios, ESP32 employs the time RF Coexistence [中文] Overview ESP boards now support three modules: Bluetooth (BT & BLE), IEEE 802. 4 GHz ISM band RF module, shared by two or three modules. Here in this example if I adds functionality for Wi-Fi smartconfig (ESPTOUCH) then smart configuration do not works. In this demo, The Wi-Fi function is demonstrated by measuring its transfer rate, using the iperf protocol; The Bluetooth function is demonstrated by the fast provisioning function.
