Re: how to set BLE transmit power above 3dB?
Hello. This function is provided by ESP-IDF. And you can use it in following ways. /** * @brief Set BLE TX power * Connection Tx power should only be set after connection created. * @param power_type : The type of which tx power, could set Advertising/Connection/Default and etc * @param power_level:...

Re: Support for Bluetooth 5.1 or 5.2 ?
ESP32 has just passed BLE 5.0 certification. However, at the moment, we don’t have any plan to upgrade the existing ESP32 hardware to BT/BLE 5.1. Thanks.

Re: esp32 ble开启后,导致GPIO39中断不正常
你好,我用你的代码尝试了在 SPP 例程中添加了 GPIO39 的中断程序,但是并没有发生你提到的中断会被一直触发的情况,当引脚碰到其他地方时确实会多次触发中断,这是因为引脚采集到了毛刺信号。BLE 工作时会发送射频信号,这个操作的顺时电流较大,我建议你首先检查一下你的电路供电是否稳定,再检查该引脚是否受到其他电信号的干扰,如果有示波器可以显示在示波器上观察一下是否外部引入了毛刺信号。
