Qn908x OTAP Question

[Corgi]

Hello,
I'm a newbie developer in which to develop a code for OTAP on the QN9080SIP-DK.

I use sample codes from the sdk examples:

bluetooth_otap_client_att _freetos
framework_bootloader_otap_bm

And read Bluetooth Low Energy Demo Applications User Guide.pdf

Before Usage IoT Toolbox, I should Flash the OTAP Client ATT and OTAP Bootloader into my board (Qn9080), What should I do?

Environment:
MCUXpressoIDE v11.2.0
SDK Version 2.2.5 QN908XCDK

I guessed maybe use QN908x Programming Tools, Is there any user guide for QN908x Programming Tools? I don't know how to Flash OTAP_CLIENT_ATT and OTAP_BOOTLOADER on my board.

I just want to achieve OTA by Sample Codes.
Thanks,

Hi @mario_castaneda ,

Final question, Is there have Toolbox OTAP source code or SDK for us develop our app(iOS/Android)?

Or Protocol, Related documents

The use situation is that I need to develop in my APP

Hi @Corgi,

The IoT Toolbox source code can not be shared. Please get in contact with your DFAE for more information about this.

Hi @mario_castaneda ,

How about Programming Tool Source Code or Protocol Docs ? Or I also need to get help from DFAE,

Are there any other documents about integration? When I conduct OTA on my project, it will fail at 8%

Hi @Corgi,

Sure, for more information about the IoT Toolbox, please get in contact with your local DFAE.

You can follow the next document to integrate OTA into your project.

Hi @mario_castaneda 

OK,I will contact with DFAE.

Can I programming on MCUXpressoIDE? After complier it will not work, but work by qn908x Programming Tool, What should I setting about bootloader and otap project?

[mario_castaneda]

Hi @Corgi,

Sure, I used the MCUxpresso IDE for this OTAP test and it works.

What is the issue that you have?

Hi @Corgi,

I confirmed internally, the IoT Toolbox does not support .s19 file, only supports .srec and .bleota file. You can change the .s19 to .srec directly，then the firmware can be updated successfully.

Hi @mario_castaneda,,

Yes, I use SDK Example "bluetooth_otap_client_att" & "framework_bootloader_otap", and Steps by QN908x Programming Tool User Manual 4.4.5

So, I program the otap bootloader and otap_client_att on my board,
After press ADVSW I can see my device in the list of scanned devices,

but when I try to connect device, I see Status shows that connecting -> connected (only 3secsonds) -> disconnected,

Why is it disconnected ?

Another problem is I selected my .s19 file , but File Infomation No any changes,

Is it because the device is disconnected? Or is my .s19 file something wrong?

.s19 file is also use SDK example "otap_client_att"

Environment:

IoT Toolbox: 5.1.11

QN908x Programming Tool: 1.0.2

Hi @Corgi,

So, I program the otap bootloader and otap_client_att on my board,

What is the process that you followed to program these 2 codes?

but when I try to connect the device, I see Status shows that connecting -> connected (only 3secsonds) -> disconnected,

Did you enable some security features? Just to confirm, are you using the IoT ToolboxApp?

Is it because the device is disconnected? Or is my .s19 file something wrong?

Does this happen when you try to update the firmware?

Mario

Hi @mario_castaneda,
What is the process that you followed to program these 2 codes?

I just build the project, Go Binaries/ file .axf Binary Utilities / Create Bin and Create S-Record, (MCUXpress IDE)

So I got the bootloader_otap.bin, otap_client.bin, otap_client.s19 and programming by use Qn908x Programming Tool,

Today I use another iPhone I can correctly connect my device, No disconnection.

But I Tapped Open and selected my .s19, File Infomation is still no change,

Can you give me demo .s19 file?

Hi @Corgi,

I programmed the device using the same examples that you are using.

It works by my side. Please look at the bin and s19 files, and also look at the images.

Hi @mario_castaneda ,

It is still not working on iPhone, but working on Android,

in iOS 13.1.2 I can connect my device but can't select .s19 file (File info no change),

in iOS 14.0 and 14.5.1 will auto disconnected (File info no change),

in andoid 8.0 as iOS 13.1.2 can connect my device but can't select .s19 file (File info no change),

successfully work in android 9.0.

All App Version: 5.1.12

Hi @Corgi,

I reproduced the issue using an iPhone and it is not working. we are checking and get back to you as soon as possible.

Is there any Reference or Doc about otap_client_att integrated into my project

[mario_castaneda · Accepted solution]

Hi @Corgi,

Sure, you could take as reference the next App note

4 Customizing a based Bluetooth LE demo to integrate the OTAP service.

https://www.nxp.com/docs/en/application-note/AN12970.pdf

Keep in mind, that the AN is for the KW36, but you could look at the application level.

Hi @Corgi,

Have you programmed a simple example using the IDE that we provide?

Before Usage IoT Toolbox, I should Flash the OTAP Client ATT and OTAP Bootloader into my board (Qn9080), What should I do?

Yes, you have to program the bootloader before using the OTAP Client example, you could import the example and flash the code using the MCUxpresso or you could use the Jlink commander to load the bin file.

Mario
