ESP32 Examples

[anteph]

Hi,

I'm creating some tutorials / examples for the ESP32 Arduino support at my blog:
https://techtutorialsx.com/category/esp32/

I'm covering both basic topics and also some more advanced ones, such as the use of some FreeRTOS functionalities. I'm also including some explanations and images of the expected results.

Hope it helps others getting started with ESP32 development.

Best regards,
Nuno Santos

I saw your blog. Looks interesting will be useful to me and others. Request you to do tutorials / examples on bluetooth BLE client and server.

But according to me this should not be created as an issue. You could put it on ESP32 Forum under sample code etc. - https://www.esp32.com

Maybe we can link the tutorials to the documentation :)

@tushaar , thank you for the feedback :) As soon as I have some time I will test BLE and try to post some content about it. Right now I'm playing with RTOS and the execution of code in the two cores of the ESP32.

I didn't know where was the best place to post the link, so I opened the issue in hope someone would see it and move it to the appropriate place. Thanks for the recommendation, I will share at the forum. Should I close this issue or the appropriate action is to wait for a collaborator to close it?

@me-no-dev let me know which links you recommend me to include in the posts, I have a related content section that I usually use to complement the information of the tutorials. I also try to include references and links to the content I consult when creating the tutorials. Thanks :)

@anteph You could ask http://esp32.net to add your blog under reading and videos. I used that site to get started.

can you post an example for BLE on esp-32 arduino?

Yes, do need a BLE/WIFI for ESP32 ,On 05/14/2017 05:22, SarahAshraf wrote: can you post an example for BLE on esp-32 arduino? — You are receiving this because you are subscribed to this thread. Reply to this email directly, view it on GitHub, or mute the thread.

Hi! I haven't yet played with BLE sorry. But as soon as I have some content about it I will share here.

For WiFi I have this one bellow, which explains how to connect to a WiFi network. It's a very simple example and the method for connecting is similar to the one used in many of the examples of this repository.

Then, I have some more complex examples, built on top of the WiFi functionality, on how to publish and receive MQTT messages:

https://techtutorialsx.com/2017/04/29/esp32-sending-json-messages-over-mqtt/

Since this is a topic that I think will be of interest, I will also leave the link for this post on how to run FreeRTOS tasks on the two different cores of the ESP32, so we can start exploring some dual core functionality:

Did you ever end up working BLE in arduino with the esp32, would love to see a tutorial for that.

Hi! Unfortunately I haven't explored BLE yet, although I've been looking into Bluetooth Classic features. I have a couple of tutorials on those, although they are for ESP32 IDF. If they are of interest, let me know and I will share the links here.

Best regards,

Hi anteph,

I would actually greatly appreciate that Bluetooth Classic tutorial for arduino. Thanks.

Hi anteph, I would greatly appreciate those links. Thanks, Skyler

Hi! Here are the links, hope they are helpful. As mentioned, they are for IDF, not Arduino:

• Using the BTStack Library: https://techtutorialsx.com/2017/07/08/esp32-bluetooth-using-the-btstack-library/
• Advertising a service with spp: https://techtutorialsx.com/2017/07/17/esp32-bluetooth-advertising-a-spp-service-with-sdp/
• Receiving data with RFCOMM: https://techtutorialsx.com/2017/07/09/esp32-bluetooth-rfcomm/
• Finding a ESP32 BT device with Python: https://techtutorialsx.com/2017/07/09/esp32-bluetooth-finding-the-device-with-python-and-btstack/

Would be awesome if someone could find a way of using the BTStack library on the Arduino core!
