Thanks Akshay, everything looks clearer now 🙂

All zipfiles are now replaced with files on their actual locations. Please find RP2040_connect and XAIO_nRF52840_sense on embedded links.

Thanks again for your suggestion!

Best,

Akshay

Hi Hieu ,

Thanks for a prompt reply! The contents are listed here (on Github and the README file also has the notion link). However we will publish the sources for samples and object files for OTAinfo libraries.

The Slack channel is to support users who wish to use OTAinfo library. It is created by OTAinfo, Inc.

Best,

Akshay

Hi Akshay,

I am not the one with question in this thread but thank you for trying to help. I am sure the topic creator, vgarcive, has received notification of your response.

However, I have looked at the links you provided and would like to have some feedback.

The presentation of the library and links made it possible to see your answer as suspicious.

Firstly, please do not distribute library in .zip file on GitHub. It is not clear what the zip file contains. You should publish the source code along documentation, no matter how brief.

Secondly, as you are referring people to a Slack channel. I would like to ask you to give a few words about what the channel is about, and who are there.

My apology if you are trying to help and my words discourage you. That isn't the intention. Please take my reply as suggestions to make your contribution better received.

Best regards,

Hieu

Hi Hieu ,

Not sure if you already got a solution or not. You can checkout our sample library for XIAO nRF52840. Let us know if you face any issues on our slack channel.

Best,

Akshay

Hi there,

How low?

You can use MIT app inventor and the notify on the BLE service and Alerts are almost Immediate.

I have the Xiao nRF52840 Sense with the IMU onboard, Both notifications are sent to the MIT app instantaneously for Motion (if the device is moved or picked up) and FALL detection (tracks a free-fall ) and in the app indicates it's been dropped. I use the read and writes to set the sensitivity of each service and the read to verify. But it also could be used to read the actual DATA from the IMU btw.

HTH

GL :-) PJ

I use custom wav files also to indicate which event has occurred so If I'm not in the room I know.

Hi vgarcive,

We have generic information about bonding here: Lesson 5 - Security in Bluetooth LE communication. This is part of our free online courses on DevAcademy.

As for how to implement bonding on your platform, that is outside of my expertise, more so without knowing what platform it is. However, I am almost certain that implementing bonding is more complicated than adding a notification enabling.

Hi Hieu,

Thank you for the information given. I know that probably enabling the notifications on an app should be easy but I am kind of using a low code platform for the app so I do not have much control of the BLE, that was the reason behind asking this questions.

Do you have a link where I can check how to properly do the bonding? I think I am going to explore that solution.

Thank you!

Hi vgarcive,

There is an old DevZone case on this topic and the answer is still valid now:
RE: How to enable notification on the peripheral side?

If you really need the notification working without having to be re-enabled from the client, you can use bonding. Note that when you have a dedicated phone app for your application, enabling notification is just one line of code, and a moment in real time, not user-recognizable at all.

A more convoluted solution is to have the Server on the Central, and the Client on the Peripheral. That way, the data from the Peripheral is sent with a Write instead, not requiring Notification enabling. This approach is very rarely used and doesn't bring any big benefit though.
