| GPIO | Support | |
| UART | Support | Using LUATOS_ESP32C3 development board requires connecting serial port to USB chip UART0_TX and UART0_RX (such as CP2102) |
| JTAG debug | Support | ESP32C3 usb-linked development boards can be debugged |
| WIFI | Partial support | There are currently some problems, such as `rt_mq_recive` cannot be used in ISR, etc., and we are still trying to solve it |
| BLE | Partially supported | There are currently some problems, such as running errors caused by the same `PC` and `SP` pointers after `NimBLE` is started for a period of time |
| WIFI | Partial support | There are currently some problems, such as `rt_mq_recive` cannot be used in ISR, etc. |
| BLE | Partially supported | There are currently some problems, such as `NimBLE` running errors after starting for a while |
| GDBStub | Support | You can use the GDB provided by ESP-IDF by turning on the `BSP_ENABLE_GDBSTUB` switch, which will enter GDB mode after a chip error |
Note:
1. WIFI and BLE cannot be enabled at the same time. When using the BLE driver, be sure to turn off the `RT_USING_WIFI` and `LWIP` switches in `menuconfig`. In addition, due to limited personal abilities and lack of debugging equipment, there are problems with the operation of WIFI and BLE drivers. If you can solve it, please contact me [timwcx@qq.com](mailto:timwcx@qq.com), I will be grateful.

2. The BLE driver only supports `NimBLE` and is provided by the `bluetooth` component in `esp-idf`. To use the BLE driver, please refer to `bsp/ESP32_C3/packages/ESP-IDF-latest/examples/bluetooth/nimble` Sample program, please note that the `esp_timer_init()` function must be called to initialize the clock driver before calling the `NimBLE` related interface.

| GPIO | 支持 | |
| UART | 支持 | 使用LUATOS_ESP32C3开发板需要在UART0_TX和UART0_RX连接串口转USB芯片（如CP2102）|
| JTAG调试 | 支持 | ESP32C3采用USB方式和PC链接的开发板可以调试 |
| WIFI | 部分支持 | 目前存在一些问题，例如不能在ISR中使用`rt_mq_recive`等，还在尝试解决中 |
| BLE | 部分支持 | 目前存在一些问题，例如`NimBLE`启动一段时间后`PC`和`SP`指针相同导致运行错误 |
| WIFI | 部分支持 | 目前存在一些问题，例如不能在ISR中使用`rt_mq_recive`等 |
| BLE | 部分支持 | 目前存在一些问题，例如`NimBLE`启动一段时间后运行错误 |
| GDBStub | 支持 | 通过开启`BSP_ENABLE_GDBSTUB`开关即可使用ESP-IDF所提供的GDB，其会在芯片出错后进入GDB模式 |
注：
1、WIFI和BLE不能同时启用，在使用BLE驱动时注意在`menuconfig`中关闭`RT_USING_WIFI`和`LWIP`开关。另外由于个人能力有限且缺乏调试设备，WIFI和BLE驱动运行都有问题，如果可以解决联系我[timwcx@qq.com](mailto:timwcx@qq.com)，本人感激不尽。

2、BLE驱动仅支持`NimBLE`，并且由`esp-idf`中的`bluetooth`组件提供，使用BLE驱动可以参考`bsp/ESP32_C3/packages/ESP-IDF-latest/examples/bluetooth/nimble`下的样例程序，注意在调用`NimBLE`相关接口之前要调用`esp_timer_init()`函数初始化时钟驱动。
