LAUNCHXL-CC2640R2: Did not ask Passcode

I used two different iPad BLE applications, Light Blue and TI SimpleLink Starter. Neither one got the 'Passcode' request.

Hi,

Thanks for the reply.

I am also using CCS8.3 with simplelink_cc2640r2_sdk_2_40_00_32.

I looked at the my CCS Installation Details and attaches a screen capture here.

What compiler version are you using? BTW, I am using Windows 10 with Lenovo Laptop.

I looked at the release note:

SimpleLink CC2640R2 SDK 2_40_00_32 was built & tested on a Windows host platform using the following Integrated Development Environments (IDEs) and components. Using an IDE or toolchain version not listed below may result in compatibility issues with this SDK release.

• IAR Embedded Workbench: EWARM-8.20.2
• TI Code Composer Studio: CCS-8.3.0.00009
• TI Code Generation Tools for ARM: 8.1.4.LTS
• XDCTools: 3.51.01.18

Any suggestion?

Thanks,

Steven

Hi,
On the release notefor SDK 'simplelink_cc2640r2_sdk_2_40_00_32', it states the test is for "TI Code Generation Tools for ARM: 8.1.4.LTS".

My CCS ARM Compiler Tools is: 18.1.5.

Is this correct version?

Thanks,

Steven

Hi,
More information:

The following code did get call during bootup stage. The breakpoint was triggered.
*****************************************************
static void multi_role_processPasscode(gapPasskeyNeededEvent_t *pData)
{
// Use static passcode
uint32_t passcode = 123456;
Display_print1(dispHandle, MR_ROW_SECURITY, 0, "Passcode: %d", passcode);
// Send passcode to GAPBondMgr
GAPBondMgr_PasscodeRsp(pData->connectionHandle, SUCCESS, passcode);
}
************************************************************

However, I was never asked a 'Passcode' when I tried to make the connection from iPad application.
How can I make this happen: Ask for 'Passcode' on the iPad application?

Thanks,

Steven

Can you attach sniffer log?
can you reproduce it using phones?

Can you specify the iOS and iPad version?

Hi Christin,

I don't have a BLE Sniffing device right now?

Yes, my Android phone had the same problem.

I used two differ iPad, iPad 5 (iOs version 12.1.4) and iPad 2017 (iOs version 12.1.1).

In this version of mine, I changed the predefined symbol 'MAX_NUM_BLE_CONNS' from 1 to 3 since I wanted my board to be able to do 'Advertising' when there were still connections.

More information: 

Yesterday, I used a different computer (windows 10) to import a fresh new 'Multi-role' project. Did not make any change and tried.

In the first few times, the iPad did pop-up 'Password' window and I had to enter the passcode, 123456. But, after a few time, it never asked anymore. I could access all BLE data on the LaunchPad immediately.

Thanks,

Steven

Hi,

Thanks for the reply. I read your link and understand much better now.

Do you have a way to clean the Paired and Bonding cache so the Passcode will be asked every time when I try to connect to the LaunchPad?

Thanks,

Steven

Hi Christin,

Thanks for the reply.

I tried the tasks on your link: dev.ti.com/.../

It worked.

Based on your link, I also tried your suggestion. It did ask me the password when I tried to access the 'encrypt' Char. value.

But, I still got in immediately when I got connected to the LP.

In other words, GATT encryption worked as expected. But, I still did NOT see the password pop-up window when my iPad tried to connect to the LP.

How can I make this happen?

BTW, I also did your suggestion to let iPad forget my LP BLE device.

Thanks,

Steven

I am not following what you are saying here:
You first said "It did ask me the password when I tried to access the 'encrypt' Char. value." and then you said "I still did NOT see the password pop-up window when my iPad"
Can you provide more detail? Are you talking about different devices?

Your iPad has never managed to ask you for the passcode?

Hi Christin,

In the project that you provided the link: dev.ti.com/.../

When the iPad application tried to connect to the LP, it was never asked passcode. Instead, iPad application would be asked the passcode when it tried to access the 'encrypted' Characteristic Value (see the Task 2 and 3 in the above project link) in the same LP.

My 'multi-role' project performed the same.

In other words, my iPad was never asked passcode when it connected to the LP. But, when it tried to access the Characteristic Value with 'GATT_PERMIT_ENCRYPT_READ' permission in the same LP, it would be asked the passcode.

Thanks,

Steven
