ESP32 wroom-32怎么设置BLE MESH的广播发送功率by ynyn189 » Thu Dec 23, 2021 8:09 am esp_ble_tx_power_set使用该API接口设置ESP_BLE_PWR_TYPE_ADV和ESP_PWR_LVL_N12—-12dBm,通信距离仍在4m以上,看以前的帖子,设置的参数一致,通信距离在1m以内。请问用法对吗?如何将通信距离控制在1m内...
在ESP32 IDF中BLE广播示例程序multi_adv_demo里,演示了同时广播多种不同类型的广播,其中: 1. 1M phy extend adv 使用1Mbps的PHY速率,可连接广播。 2. 2M phy extend adv 使用2MBps的PHY高速广播,可扫描。 3. 1M phy legacy adv, ADV_IND 1M 高速广播, ...
