WL1835MOD Bluetooth Low Energy

Beatriz Soriano Saura

Other Parts Discussed in Thread: WL1835, CC2540, WL1835MOD

Dear Sir,

I am trying to connect WL1835MOD Bluetooth Low Energy(Bluetopia stack on Linux) with CC2540(we call the instrument LBT). The connection is created succesfully but it lasts less that 1 sec.
I connect the WL1835MOD BLE with BLED112 dongle(from Bluegiga, built around CC2540) with no problem.
If I try Dongle-LBT connection, there is no problem too.3286.ProblemConnect.rar

Following you can see the command and responses of the first scenario process and attached are the FTS logs of WL1835+ bluetopia enabled stack debugging

Hi Beatriz,

From the logs what I can see is that.

WL18xx has initiated a LE connection and is been accepted by CC2540.
After connection complete the CC2540 device, sends the L2CAP_Connection_Parameter_Update command to update the connection parameters with the parameters: Connection interval Min = 7.5, connection interval Max=7.5, Connection supervision timeout =10000.
But it is rejected by the Bluetopia stack(WL18xx), as the min/max connection interval as set to 10 and 20 respectively by the Bluetopia stack device (and the spec allows the master to reject the connection_parameter_update from slave).
After this, I think the connection is dropped because of LSTO.

I have try to test the same scenario on my side with the same connection parametes, unfortunately the CC2540 does not send any update parameter request, so my connection does not disconnect (same as with Dongle).

I think you can try changing the Connection interval Min value to >= 10 and Connection interval Max value to >= 20 on CC2540 and try the same scenario.

Alternatively, you can try to use the “Bluetopia” binaries (example on how to run: ./LinuxSPPLE 1 1 3000000, located at BluetopiaPM\Bluetopia\bin) where there is no restriction on connection interval min/max.

Please, see here feedback from the Customer:

Hello,

I am afraid I can´t modify CC2540 software. I have tried the other way you propose:

Now the CC2540 is on::

Client>ConnectLE 1CBA8C1B7635

Connection Request successful.

Client>DiscoverSPPLE 1CBA8C1B7635

No Connection Established

Function Error.

Client>

Client>DisconnectLE 1CBA8C1B7635

Unable to disconnect device: -1.

Function Error.

Now the CC2540 is off:

Client>ConnectLE 1CBA8C1B7635

Connection Request successful.

Client>ConnectLE 123456789123

Connection Request successful.

Client>

The device 123456789123 doesn´t exist.

It doesn´t work apparently, why?

Hello again,

The result has changed, I don´t know why, maybe is for a RF reason. Now apparently there is communication between both LE devices, but now the behaviour of the bluetopia stack + CC2540 is similar to the one we observed at the beginning with LinuxSPPLE_SPP:

Client>ConnectLE 1cba8c1b7635

Connection Request successful.

Client>etLE_Connection_Complete with size 20.

Status: 0x00.

Role: Master.

Address Type: Public.

BD_ADDR: 0x1CBA8C1B7635.

LE>

etGATT_Connection_Device_Connection with size 16:

Connection ID: 1.

Connection Type: LE.

Remote Device: 0x1CBA8C1B7635.

Connection MTU: 23.

LE>

etGATT_Connection_Device_Disconnection with size 16:

Connection ID: 1.

Connection Type: LE.

Remote Device: 0x1CBA8C1B7635.

LE>etLE_Disconnection_Complete with size 16.

Status: 0x00.

Reason: 0x13.

BD_ADDR: 0x1CBA8C1B7635.

As you may see, after a successful connection, very quick the disconnection happen.

Hello,

I just replied with the feedback from the Customer, is there a way for you to move this post to a public forum? I posted it in the internal forum by error and I would like the Customer to be able to see the answers and reply directly. Thanks, Beatriz.

Hi,

Could you please let me know what is the Bluetopia version and for what platform you are using?

The Init script(Service pack) you are using?

Bluetopia V4.0.1.3 is available http://www.ti.com/tool/linuxezsdk-am335x-wilink8

I have tested the same "LinuxSPPLE_PM" on Sitara(Am335x) + WL18xx. I don't see the issue see the logs

Hello,

Bluetopia version:

Hi,

Thank you for providing the complete details.

I suspect the Bluetopia package "AM335xBluetopiaLinuxEvaluation-4.0.1.3-linux-installer.run.exe" you are using.

Could you please take the pain of downloading the Bluetopia package again from http://www.ti.com/tool/linuxezsdk-am335x-wilink8 It should look something like

AM335xBluetopiaLinuxEvaluation_4013_linux_installer.run - if you have downloaded evaluation version.

AM335xBluetopiaLinuxProduction_4013_linux_installer.run - if you have downloaded Production

I think there was a mistake in the files uploaded to the site, and later got corrected.

I hope this will solve the problem.

Hi Francisco,

Let me summarize.

You are using BeagleBone white + BeagleBone white 18xx cap + Bluetopia version 4.0.1.3(LINUXEZSDK-WILINK8-BT-BB)
You tried to establish LE connection with CC2540, using the BluetopiaPM demo “LinuxSPPLE_PM” (executables located at BluetopiaPM\bin) and the connection is getting dropped.
You have also tried to establish LE connection with CC2540, using the Bluetopia demo “LinuxSPPLE” (executables located at BluetopiaPM\Bluetopia\bin) and the connection is getting dropped.

I don’t see this problem with the same set up and same remote device. You too don’t see the issue when you use BLED112 dongle.

You can provide me the air sniffer logs for both cases mentioned above. But It looks like the problem is in CC2540(The image you are using on that).

Dear Sundeep,

Hi,

I hope you are having problem with the "IndigoBLE_V1_1_1_3.hex" image, right?

I have tried it on my side and I don't see any disconnection even after 1 minute.

I think I have not mentioned that I am using the https://github.com/TI-ECS/bt-firmware/blob/master/Bluetopia_InitScript_for_TI_WL8.zip service pack.

and also It will be great if you can provide the sniffer logs in ".cfa" format as provided initials.

DEar Sundeep,

I got the air sniffer log from TI packet sniffer, and cfa logs from bluetopia stack. I don´t know how to convert between each other.

Hi,

Yes, I have tried with "IndigoBLE_V1_1_1_3.hex" and it connects fine.

From the logs(.psd format) you have provided, I can only see the Advertising indication, I don't see any connection happening.

Hi,

What I can see is you have provide me the logs with WL18xx and LBT for failure case and Dongle and LBT for successful case logs.

My analyses provided in the first post stands.

Successful case( SIG_Connection_Param_Update_Req is accepted):

Failure case( SIG_Connection_Param_Update_Req is rejected):

The SIG_Connection_Param_Update_Req, rejected case is not handled properly by CC2540, so the connection is dropped. Please check it on CC2540 forum.
