Comprehensive Guide in Building

proDev-Theron commented 4 years ago

I already installed the idf [https://github.com/espressif/esp-idf] and I'm sure because I can run it . The only thing missing is how to build the edited main.c and flash it to the esp32 board. I hope you can make a comprehensive guide, preferably with video or screenshot.

proDev-Theron commented 4 years ago

I think I'm making progress. Forgive me for I'm such a newbie. I'm still hoping for a comprehensive guide.

proDev-Theron commented 4 years ago

I ran idf.py app I hope I can make this work soon. though I've been waiting for 10 minutes already, I hope it's building now.

proDev-Theron commented 4 years ago

I think I already built and flashed this to the ESP32 board, but nothing happens. It's not yet connected to the router nor displaying an Access Point to other devices.

proDev-Theron commented 4 years ago

I think It's done. Though no one answered me, I want to thank the author for this post. Finally after days of searching and an hour of installing and configuring idf. Next step I want to know is how can I monitor it remotely.

Thank you again @jonask1137

Sze-Huang commented 4 years ago

Can you make a comprehensive guide based on what you did? I am new to this too

proDev-Theron commented 4 years ago

I just figured it out a while ago and the process just took me an hour all in all. I update here live despite of the slow internet connection.

First I did was to download esp-idf(link in the first post) I just read the docs on how to install. This is where I spent most of my time because of big file sizes you'll need to download.

Then proceed to copying @jonask1337 lwip to esp-idf/components/lwip folder as he instructed in the original post.

Clone the example he provided and modify it according to your needs

After that just build it and flash to your esp32 Instructions are on esp-idf docs

proDev-Theron commented 4 years ago

I guess we're on the same time zone, please do yourself a favor, sleep.

jonask1337 commented 4 years ago

Hi, does everything work for you now? Sorry that the installation caused problems, I will add a more detailed installation guide in the next days.

Sze-Huang commented 4 years ago

I am able to do all the steps following the instructions. But I dont have connection to the internet. Anyway to debug it?

@Sze-Huang Looks like NAT is not enabled. If the lwIP library with NAT is used correctly by the ESP-IDF there should be a "NAT is enabled" message in the log.

Did you clone the lwIP library with NAT or did you just download it? It is only working if you clone the lwIP library with NAT and copy the repository to /esp-idf/component/lwip (after renaming or deleting the old /esp-idf/component/lwip/lwip directory).

So make sure you do the following steps:

Get the lwIP library with NAT git clone https://github.com/jonask1337/esp-lwip.git
Rename or delete original lwIP library folder (/esp-idf/component/lwip/lwip)
Copy the lwIP library with NAT repository folder from step 1 to /esp-idf/component/lwip and rename it to lwip.
Build and flash the example project again.

jonask1337 commented 4 years ago

I added a short instruction for the setup of the project to the readme here: https://github.com/jonask1337/esp-idf-nat-example

I hope this can clarify the installation process for you. If there are any suggestions for improvement please let me know.

Sze-Huang commented 4 years ago

I understood step 2 wrongly and deleted /esp-idf/component/lwip folder. I had redo again, but still unsuccessful. Still no connection to the internet.

@Sze-Huang Ok, NAT seems to be enabled now. Did you set the "Enable copy between Layer2 and Layer3 packets" option via menuconfig? (Just added this step to the Readme of the esp-idf-nat-example project because it was only in the Readme of the lwIP library)

Sze-Huang commented 4 years ago

@jonask1337 Thanks for the help! I am now able to connect to the internet after the menuconfig steps, guessed I missed that too. Appreciate your detailed instruction :)

proDev-Theron commented 4 years ago

@Sze-Huang Looks like NAT is not enabled. If the lwIP library with NAT is used correctly by the ESP-IDF there should be a "NAT is enabled" message in the log.

Did you clone the lwIP library with NAT or did you just download it? It is only working if you clone the lwIP library with NAT and copy the repository to /esp-idf/component/lwip (after renaming or deleting the old /esp-idf/component/lwip/lwip directory).

So make sure you do the following steps:

Get the lwIP library with NAT git clone https://github.com/jonask1337/esp-lwip.git

Rename or delete original lwIP library folder (/esp-idf/component/lwip/lwip)

Copy the lwIP library with NAT repository folder from step 1 to /esp-idf/component/lwip and rename it to lwip.

Build and flash the example project again.

I guess it's better if it will be visible on the README Thank you @jonask1337

Here's mine for the mean time: I put it inside an old flashlight for protection against water and dust. I used a 5V battery from an old bluetooth headset connected to VIN and GND but I think I'm hurting the board so I switched to using power bank connected to the USB port.

I want to add functions such as: 》blinking the other built in LED when there is data transfer 》Signal strength represented by LEDs in the GPIOs 》Live Monitoring via Web Browser (bandwidth, connected clients and their MAC Addresses, Plot Monitor of Current Speed, etc.) PS: I plugged this repo on a facebook group. Some showed interest about this project. They're asking for code so I referred them here. @jonask1337 https://www.facebook.com/groups/esp8266microcontrollers/833783540404465/?comment_id=833801633735989&notif_id=1578591678996951

@proDev-Theron Thanks for your feedback and sharing your project status! It is always interesting to see what other people come up with. ;)

I updated the Readme. For a detailed instruction I would refer to the Readme of the https://github.com/jonask1337/esp-idf-nat-example project. It should be easier to follow now...
