Tool/software: Linux

Hello,

my board :

wl1837

Bluetopia Platform Manager 4.2.1.1.1.0

After rebooting my board, I have a problem to write an encrypted characteristic,

I have the error "Encryption is insufficient" with Ios.

After this reboot, I observed a change in the BTPMLECFG.btc file.

the parameter SC-00000000 has changed:

before the reboot :

SC-00000000=AED4F5DBF5F40203FFFF

after the reboot:

SC-00000000=AED4F5DBF5F400000000

My pairing configuration :

st_authResponseInfo.BD_ADDR   = pst_iRequestData->BD_ADDR;
st_authResponseInfo.AuthenticationAction  = DEVM_AUTHENTICATION_ACTION_IO_CAPABILITIES_RESPONSE;
 
if(!LowEnergy)
{
  st_authResponseInfo.AuthenticationDataLength                                   = sizeof(st_authResponseInfo.AuthenticationData.IOCapabilities);
  st_authResponseInfo.AuthenticationData.IOCapabilities.IO_Capability            = (GAP_LE_IO_Capability_t)icDisplayOnly;
  st_authResponseInfo.AuthenticationData.IOCapabilities.MITM_Protection_Required = true;
  st_authResponseInfo.AuthenticationData.IOCapabilities.OOB_Data_Present         = false;
}
else
{
 st_authResponseInfo.AuthenticationAction                                       |= DEVM_AUTHENTICATION_ACTION_LOW_ENERGY_OPERATION_MASK;
 st_authResponseInfo.AuthenticationDataLength                                    = sizeof(st_authResponseInfo.AuthenticationData.LEIOCapabilities);
 st_authResponseInfo.AuthenticationData.LEIOCapabilities.IO_Capability           = (GAP_LE_IO_Capability_t)licDisplayOnly;
 st_authResponseInfo.AuthenticationData.LEIOCapabilities.Bonding_Type            = lbtBonding;
 st_authResponseInfo.AuthenticationData.LEIOCapabilities.MITM                    = true;
 st_authResponseInfo.AuthenticationData.LEIOCapabilities.SC                      = true;
 st_authResponseInfo.AuthenticationData.LEIOCapabilities.P256DebugMode           = false;
 st_authResponseInfo.AuthenticationData.LEIOCapabilities.OOB_Present             = false;
 st_authResponseInfo.AuthenticationData.LEIOCapabilities.Keypress                = false;
}

My question :

What is this SC parameter in the BTPMLECFG.btc file and why is it changed?

Best regards,

Thomas.

Can, you take BTsnoop logs, from the beginning after reboot?

Thanks

Hello Hari,

you will find in attachment 2 logs.

As you wished, a log after reboot (BTPMHCILog)

And a second log named Log_with_paired, contains the paired process and the error enrcrytion.

thanks for the analysis

Best regards

Thomas

Hi Thomas,

I tried the scenario with 'LinuxGATM_SRV' demo and it seems to work fine.. I do not see any changes to the 'BTPMLECFG.btc' file either in between reboots or reconnects.. Attached is the log.. Can, you also try to reproduce with GATM_SRV demo?

Hi Hari,

Yes I can reproduce with GATM_SRV demo.

I do the following actions :

//start SS1BTPM and GATM_SRV

SS1BTPM& ./LinuxGATM_SRV

1 1

10 1

registerauthentication

registergattcallback

StartAdvertising 0x77 100

41 1 3 0 GattDebug2.log

ChangeLEPairingParameters 1 1 1 1 0

registerservice 3

//On the smartphone, I write the encrypted characteristic, with uuid :

//{ 0x6A, 0xFE, 0x77, 0x51, 0x6C, 0x52, 0x10, 0x14, 0x8B, 0x7A, 0x95, 0x02, 0x01, 0xB8, 0x65, 0xBC },

//This action starts bonding process, I must confirm user :

UserConfirmationResponse 1

//I disconnect my smartphone. I must restart advertising :

StartAdvertising 0x77 100

//I write the same characteristic, it is ok

//I stop GATM_SRV and kill SS1BTPM

//I restart the scenario:

SS1BTPM& ./LinuxGATM_SRV

1 1

10 1

registerauthentication

registergattcallback

StartAdvertising 0x77 100

41 1 3 0 GattDebug2.log

ChangeLEPairingParameters 1 1 1 1 0

registerservice 3

//I try to write the same characteristic, but it is NOK.

//I look the debug file (GattDebug2.log) with wireshark

//and I see error "Insufficient Encryption"

You will find in attachment the file GattDebug2.log.

Thank you for your analysis.

Hi Hari,

Did you manage to reproduce the problem with GATM_SRV demo ?

Hi Thomas,

Yes.. I was away and could n't get back earlier.. Will, get back in couple of days..

Hi Thomas,

Instead of killing the daemon, on the 2nd try, i powered down the controller and restarted it.. It worked fine.. Can, you try this.. I wonder, if killing the BTPM sever is corrupting the BTC file..

Hi Harry,

I'm Thomas coworker. He is currently on vacation, he's coming back next week. I'll try to reproduce what you describe but i haven't got all elements for this.

I will let Thomas try it and he'll respond you as soon as he came back.

Thank you for your help.

Hi Harry,

Yes, it works correctly without shutting down SS1BTPM (just a few tries).
But we have to stop SS1BTPM (restart by user or by empty batteries).

What do you advise?

Best regards.
Thomas

Hi Thomas,

I believe, it is a question for general embedded linux forum. I would tend think, the file system should ensure to recover properly in the event of a power failure. It appears Journalling EXT3 file system would take care of it.. Please, check your host file system.

Thanks

Hi Hari

yes, I can ask this question on another forum but I have the impression that it's not a generic file problem. That's my opinion.

I checked the integrity of the file by checksum (md5sum BTPMLECFG.btc)
Before and after "Encryption is insufficient" error.
The checksum is ok. the file is not corrupted.
SS1BTPM seems manage to read but not write.

My filesystem is EXT4, I think it's a good filesystem.
Moreover, I never had a corrupted file after hard-reset or restart.

I can write BTPMLECFG.btc to linux command "vi".
Do you think SS1BTPM can't write it ? and why ?

Thanks,

Thomas.

Hi Thomas,

Try, launching the daemon with sudo (i.e root privileges) and see if it helps..

Thanks

Hi Hari,

I'm always in root privileges.

Thanks.

Hi Thomas,

Not sure, what else could be causing the issue.. I will try some more tests early next week..

Thanks

0 Thomas Rauturau over 6 years ago in reply to Hari Nagalla

Hi Hari ?

Did you try any tests?

The mobile application would be released soon. encrypted chacteristic is necessary to start bonding process.

it is becoming urgent, I really need help.

I find some thing that could help us:

At first everything works fine, the phone is paired, no encryption error.
I disconnect the phone. I save the files (BTPMCFG.btc, BTPMDEV.btd, BTPMLECFG.btc)

After a shutdown, or a sigterm of SS1BTPM, the encryption problem is always present.

If I replace the configutaton files with those saved and I restart SS1BTPM.

I don't have the encryption error, but only for the first connection.

I tried to analyze the files but it's complicated for me.
I noticed that when the "PropertiesLE" parameter (BTPMCFGd.btc) changed, it's not good.

What is this parameter?

Thank you for your help

Anyone ?

Hi Thomas,

I sent a message.. We, are simply not able to reproduce the issue with our EVMs, even after multiple power cycles..

Thanks
