Rapid IoT Bluetooth problem

[gaubuali01]

Hi,

I recently received the NXP Rapid IoT kit.

I have followed instruction from Internet to turn on the built in Bluetooth.

On the Rapid IoT kit itself, it shows the Bluetooth has been activated. However, I cannot find any Bluetooth devices by scanning from my phone or my PC.

Please advise.

Hi Richard,

I included the pictures again.

So both accounts wont work on Samsung using the newest App from G-playstore.

Then sometimes the screen shows RELOAD and ask again for username/password.

regards Ron

Thanks!

Hi Ron,

- What is your phone model? We know old BLE stacks in older phones are not very robust and Rapid IoT cannot connect to those.

Make sure the  OOB app referred above is flashed in the kit:

https://community.nxp.com/docs/DOC-342913

because this updated kit app version allows for UART over USB.

Via a terminal (like Tera Term) you could capture a log of what happens when you are connecting via BLE.

Provide me with this log so I can analyze what is happening.

Looks like

Eric,

I tried it on Nexus5X android 8.1.0 All standard BT settingss used.

I installed the new sw package. After Reset of the device and enabling Teraterm, this was the logging:

==============

But since I cannot connect anymore to https://rapid-iot-studio.nxp.com/  I was not able to get it running on a newer phone yet. Just can't login.

Can you help me on this one too? I deleted the original account on the development site, but I cannot get it running it back on again. I tried several attempts to register with different accounts.

It wont send me a confirmation message to accept the account.

thanks again

Ron

Hi Ron,

The log you provided looks ok, except that there is no indication you tried to connect via BLE. Looks to be a normal log for the boot sequence.

I would like you to capture the log during provisioning and BLE connection.

In the mobile phone application got there:

and tap either the top right icon or the ' + ' in the middle of the screen, then selcet your kit and provision it.

This will/should trigger:

[NFC] Registration Set                                    <=== This is where you stopped

GAPConnectionEventConnectedIndication   <=== Here he BLE phone connection ' request"

I need the missing part of the log to figure out what is the potential root cause.

Hi Eric,

I will try but I am stucked when I am requested to login in the app, so I wont get the screens you showed.

"But since I cannot connect anymore to https://rapid-iot-studio.nxp.com/ 

I was not able to get it running on a newer phone yet. Just can't login. 

Can you help me on this one too? I deleted the original account on the development site, but I cannot get it running it back on again. I tried several attempts to register with different accounts.

Hi Eric,

I used another laptop, another  account and another browser (first chrome now FF) to recreate a new IDE environment on my laptop. The acceptance message came directly. I reset the device to factory.

So I can connect to the IDE.  This works so for far with this laptop and FF. In the IDE the IoT device is not recognised in this new setup. The icon "add device"is not displayed. so no provisioning can be performed.

I am not able to connect using the same user and passwd via de RIoT app on my smartphone and so no provisioning via this way is possible. also after reinstalling this app I get the "message not found (404)".

Not able to connect to the UART anymore via tera term either.

NO "Mass storage attachement" works anymore.

Perhaps I need to flush some caches and etc. Where can I start.?? 

=========================================

Finally removed the (beta) app from smartphone and installed an older version (1.1.4) as found in one of the earlier posts.

This seems to work amd starting to authenticate BLS.

I could add and provision the device and then it responded.

I saw this happening 1 time  before in the first minute I unpacked and installed the device. So see what will happen after ..

1 minute:  no samples received anymore. (Could this be caused by opening the browser screen on the laptop)?

                  time still runs op the device.

Back to beginning of this tread.......

Hi Eric,

Spamming you again (but today is my hobby day) ;-)

Also rebooted the laptop. This enables teh com port over USB again. 

still no access from app on phone.

But manual BT connection request says: I tried 0000 and 1234 to connected and the device responded with pairing failed.

Hi,

I have tried pressing all 4 buttons until Orange Led blinking. However, there is nothing appeared on Folder Explorer. I have also check the dmesg, there is nothing changed.

I can confirm that the USB cable and my USB port are still working fine.

[frq05186]

Both should work. 

Now I am trying to duplicate your issue with W10

[gaubuali01]

Thank you. 

I will try it tonight.

To check if it is visible in file explorer, can I use my Mac or I have to use Windows 10 ?

[gaubuali01]

Hi,

It is still Out of the Box application. I cannot connect to the Rapid IoT with Bluetooth or via USB.

Yes, I beleive the the LEDs blinking is correct based on Rapid IoT instruction.

[frq05186]

That makes 2 different issues:

Issue 1: BLE connection

Issue 2: Switch to kit programming over USB mode

Both issues are likely fully independent.

Am sorry to go step by step but the failure mode you are reporting is a first of a kind.

Issue 2 first: 

==> Could you please try pressing all 4 buttons at same time until the top left LED blinks Orange? 

When the case, please check again that your kit is visible in the file explorer. 

If LED blinks orange and you still do not see your kit in explorer I will explore a potential driver issue.

Should you succeed in setting the kit in programming mode,  please flash this binary:

https://community.nxp.com/docs/DOC-342913

and try BLE connection again.

Hi,

• I am using iPhone, Macbook and Windows 10. All of them cannot see the Rapid IoT Bluetooh.
• I am using the application firmware delivery with the Rapid IoT. When I change to USB storage mode (top left and bottom right buttons), there is no USB found from my Mac or Windows 10 PC.

I followed the instruction from Internet how to program the Rapid but not succedded because I cannot communicate with it.

[frq05186]

Ok, 

The configuration you are using has been tested several time without issue -  so I am puzzled.

• From Macbook and Windows 10 you will not be able to connected over BLE via our embedded FW (Out of the Box application)
• iPhone should work perfectly using our application 

I certainly overlook an important information.

==> Can you confirm you have installed Rapid IoT application and it is the latest one ? From your text it is not clear to me whether you try connecting direclt via the iPhone bluetooth menu or via the app.

==> Are there any diode blinking on the kit ? (I mean one the kit has fully completed booting sequence)

[frq05186]

Hi,

In order to support you effectively, I need to know a bit more about your setup.

- Which phone are you using ?

- Can you confirm you are using Rapid IoT Studio to generate your project ?

- Were you able to connect to the Out of the Box or Weather station example projects available in Rapid Iot Studio ?

Do note the following:

   - the kit will not connect to a PC via Bluetooth if you are using code generated directly out of Rapid Iot Studio

   - you must have device location turn on on your phone to enable BLE connection.
