Hi Bina. I have a problem I'm facing and have spend countless hours communicating with Chinese manufacturers on Alibaba over the last year with no success. You seem to know allot about this stuff. Can you perhaps give me some ideas if I explain my problem.

[@BinaBhatt]

@@louisr5208 sure. I'll try..

Wow! Weeks of wrestling with arcane and oscure articles, and this lass nails it in 40mins! I really do recommend this to anyone who has to get to grips with BLE and can't make head or tail of the buzz words. This is way, way above its competition.

Great work mam.. BT 5.0 , 5.1, 5.2, 5.3 core specifications features enhancement could be next subject we would like to understand

[@kolekarsachin]

Bina, This video is a good place to start understanding BLE. I was confused about BLE, but now have clarity. Thanks.
I might need some help to kickstart with BLE on CC2541 chip. I go for this chip as there is already a module named HM-10 available in the market and I do not have to worry about the PCB aspects of it.

[@BinaBhatt]

Thanks for the feedback. I will upload more videos on this topic, make sure you've subscribed to the channel. Do let me know if you would like to see anything specific.

Great Work Bina Keep It up. Do you have a video for a detailed explanation for Classic Bluetooth Protocol?

Thank you, not yet. I'll plan it soon!

[@YousufAlam-jx4qd]

Hello mam, can I used deep sleep features in ble connectable device?

[@runsuckerrun9034]

Great video. I was confused when the concept of server/client was introduced at the end. How to those relate to central/peripheral?

[@BinaBhatt]

I recommend you to check this video on my channel: th-cam.com/video/ccVYPDtlhps/w-d-xo.html
Do subscribe to the channel for more content related to BLE and embedded systems!

[@nitindeokate]

Hi Bina
Great videos(part1 and part2)
Two questions:
1. Where can I find the details on Central to peripheral commands/request format details?
2. Do central and peripheral have to define GAP/GATT and ATT on each of their sides?

[@BinaBhatt]

Hello Nitin, could you specify the details of the module that you are using?
2. GATT roles are of server and client. Server holds the ATT lookup data, service and characteristic definitions. The GATT client sends request to the server.

[@clapBoxguy]

Hi, thank you for good information, I want to send advertise data size of 32 byte and android not support it, hope you will suggest please how to send and share if any code or tutorials do you have.

[@iamcalledusman]

nice explanation ! impressed ! i have a question can u please answer , i m embedded system developer . As you explained in your video 10:26 , if indication send then ack will be send by the client that it receives the indication correctly .My question is that , if no indication received then protocol will send the indication again ? and how can we enable and disable this feature in ble5.0 ? i am using esp32c3 (esp-idf ) . If you could help me in this regard. Thank you!

[@BinaBhatt]

Kindly check the datasheet of your device

[@anandlekhnivlogs9701]

[@sebastiantu6212]

I'm a little confused on GAP. You say that it provides access to the Link layer operations, but isn't the HCI supposed to manage all the connections between the Host and controller layers?

[@BinaBhatt]

Check Part 1 of this series: th-cam.com/video/_CKlkHJROqw/w-d-xo.html
I've explained the operation of each layer in that one!

[@chaitanyachirravuri1173]

Hey, Is this GAP adv system possible for multiple observers and one advertiser ?

[@BinaBhatt]

There is no restriction in BLE specification on the number of observers the broadcaster can broadcast to.

[@krishnakhandelwal9466]

So is it possible for a developer to stop the advertisement once the connection is established between peripheral and central?

[@BinaBhatt]

@@krishnakhandelwal9466- check the datasheet of your BLE device. Usually, the peripheral stops advertising automatically once a connection is established.

[@rabeezyoud]

What about ble descriptor?

[@BinaBhatt]

Descriptors provide metadata/additional information about the characteristic to the client.

[@otagophysio]

can u suggest any free ios app which can collect bluetooth data from adafruit feather M0 board and plot it. thanks

[@BinaBhatt]

Not particularly sure about this. Please check the Bluefruit LE Connect on iOS.
