In this esp32 tutorial we will check how to receive data on a serial connection operating over Bluetooth classic. This tutorial will be very simple since we are going to use the BluetoothSerial library for the Arduino core, which exposes a very high level API much similar to the regular wir...
BOOT(IO09)管脚上电前不能下拉,ESP32会进入下载模式。 使用到IO08管脚进行设计,不建议外部直接下拉,因为在下载烧录时,IO08管脚为低电平,不能使用串口进行下载。 IO12(GPIO12)、IO13(GPIO13)在QIO模式下为SPI信号SPIHD和SPIWP复用,为了增加可用GPIO数量,开发板选择采用2线SPI的DIO模式,IO12、IO13并未连接flas...
