使用 idf.py erase_flash 对 flash 进行擦写,然后在 menuconfig 里开启1.png,再重新烧录程序

一樣的問題,但用了建議方法問題依然。

Re: RTC 时钟问题

我查了差不多所有ESP32 的各系列,发现用电池供RTC时,主CPU也在用电,引至功耗比外置的RTC大好多。
对比STM32, 他们的MCU在用VBat供电时,CPU core是不工作的,有些产品是需要这样以减Vcc 时的功耗。

另外是应用线路如要power off reset, 这样设置是没法重置CPU的。

我一直认为这是ESP32设计缺陷。所以还是在用STM32。

ps:内部RTC时钟精度差,这很正常,不然要外部晶振做什么?

Max Mesh network size

As per the ESP Mesh document, The size (total number of nodes) in an ESP-MESH network is dependent on the maximum number of layers permitted in the network, and the maximum number of downstream connections each node can have. Both of these variables can be configured to limit the size of the network...

Re: "Mwifi also supports the way to fix the root node" What does this mean?

So it is "no_router" mode in the examples, right? But I think the wording is confusing.

Thanks!

Re: Problem using IDF master with MDF

Hi,

What I get is from IDF is v4.0-dev-1191-g138c941fa, is this stable yet?

"Mwifi also supports the way to fix the root node" What does this mean?

In Mwifi API, https://docs.espressif.com/projects/esp-mdf/en/latest/api-reference/mwifi/index.html Mwifi also supports the way to fix the root node. In this case, the nodes in the entire ESP-MESH network cannot communicate with the external IP network through wifi. What does this mean? What is "FIX"?

How to use modified ESP32 library in PlatformIO

I have made some changes to BLE library. And I can add the library to lib folder in PlatformIO project.

But as the same time, there is original library. I know PlatformIO project is using my own one. Is that harmful without removing the original one? Or shall I replace the original one with mine?
