All the tutorials in ESP-IDF is really awesome. Thanks for making the series.

[acoolmastashu]

I can't believe that you have covered so much about BLE is a short span of time😍 Now i really feel like a pro. The way you showed the data exchange between the smartphone and esp32 ble is sp cool. Just loved this video.❤ looking forward for more video on BLE with some real-time projects. 🔥 Thanks for covering BLE with esp-idf 🔥👏

[jbart]

This video really helped me understand BLE on the ESP32. Some of the tutorials that came with ESP-IDF are overcomplicated. Your tutorial was concise and explained well. Very much appreciated!

[xkvvwdz]

You are great ashish sir 👏 how can you make every topic so easy to learn and apply. I just tried what you showed in the video. It works perfectly for me. 🎉 all credit goes to you 💞 please upload more videos on BLE so that i can visualise and image the possibilities with ESP32 and BLE. ❤ I'll request one thing to you. Please also make a tutorial on building a custom Android or iOS for this type of projects. 🔥
I'm waiting for the next video...😍

[santoshsaini]

Very knowledgeable video 👌 please make more videos on this topic ✌

Hi great! Just wondering where you got the espressif nimBLE libraries from as I can't find them anywhere? (Only for Arduino IDE)

[MrFaustotromba]

Thanks a lot. I have a questions. Why can you see on your phone also the uuid 0x1801. Where is it from?
If I want to send from the server to the client data, like " light now is on" how could I do?

[sridevipindi]

sir i have installed eclipse v4.3.1 in windows10.i have pasted the code in main.c file and built the project.I am getting the following errors "undefined reference to `ble_gap_adv_start'" and the type of error is C/C++ problem....could u tell me how to fix this got 32 errors and all are C/C++ errors....

[bccbzib]

Hello sir the tutorial created for BLE server is too good and It helped a lot . Everything you explained is really easy to understand . can you tell me how can i create a BLE client too? I want to make a network of ESP32 and connect multiple BLE servers to a single BLE client how can i replace ESP32 in place of smartphone ? It will be really help full if you public a video or just provide a reference for programming Client.

The "write data" always land in the else path in your video.There is something wrong with the code, but the generell idea is clear.

I also had a question, because I want to send from one ESP32 to another ESP32 some JSON (config) or blob (binary) files. How would you do this? Via notify or is there an elegant way of doing transfer of large data.

[ericmatevosian]

Hello, thank you for your great video. I have compiled the code but I have errors here, the vsc code error : No such file or directory
8 | #include "esp_nimble_hci.h"
I saw on the video that you added a path but I could not find that files, would you please help me?

[ranjithapalanethra]

I am still facing the error in that include path and not able to build the project can u please help me with that

[sridevipindi]

hello sir can u make a video on Bluetooth LED Control App with MIT App Inventor using espressif ide pls....we requested this topic almost 1 month before...u have covered the requested topic using arduino ide....but we would like to do using espressif ide ....

[claudiodechecchi]

Hello, nice video but your code go always in the final else. There is a problem with the strcmp function

[tarunjain]

hello sir,
i am installed the official esp-idf and just copy and paste the main program code on the main.c file but i have an error message is: error: esp_nimble_hci.h: No such file or directory can you help me with that and you just also mention the include path process so can you help me with that so i can include the path on esp-idf not using the vs code

[easyelectronics]

It was always entering into else statement can you explain that? I think there was delimiter added at the end😅😅😅😅
