    Peter Dontsendmespam
    Hello everybody, I have some problems with the Java SimplePeripheral program. It does not enable the keys of the keyfob. I think the problem is somewhere in the connectionManager in the method simpleKeysEnabler(), where the bytes are written in the outputBuffer. public void simpleKeysEnabler() {...

    Didier, The first place to start in order to get more information about the BLE stack would be to read through the TI BLE Software Developer's Guide that is installed together with the software. This describes how the stack is organized, and also contains links to other documents that provide...

  • Forum Post: Re: BT LE versus ANT or proprietary scheme

    Karl T.
    Hi Jim, For every new technology, there is going to be a period when the supply of devices that support it is limited. BLE is no different in that regard, but has an advantage in that BLE support is very easily integrated with the next series of Bluetooth chips, so that it comes "for free"...

    I just today started using the CC2540 and I've already run into trouble on step 4 of the quick start guide. It gives me instructions on how to use the "Bluetooth LE Demo" but I don't see that under the installed software. The software I installed was the BluetoothLE setup file that...

    Karl T.
    Hi Dan, I cannot provide any information on the schedule yet. As for work-arounds, connecting and disconnecting is very fast in BLE, so as long as your connection interval is not very short, you could connect and disconnect every time you fetch data. There has been some discussions in the SIG about...

    Hi Austin, We have certified our IC and software as Host (upper-layer) and Controller (lower-layer) sub-systems. Sub-systems support modular certification, so we have covered large amounts of the needed test already. However, because PCB layout etc. will be different in each case, there is a minimum...

    Karl T.
    Hi Thomas, Your steps are correct when you are in connection. This is OK as long as your XX and the mobile phone remain within range of each other. If they go out of range, then the link will be dropped after a time out. Your device must then advertise (send packets on the 3 advertising channels)...

  • Forum Post: Re: Design with CC2540, consumption question

    Karl T.
    Hi Thomas, This basically means you will be in advertising mode most of the time, and then only be in a connection when you are actually communicating with the phone. We are planning to put a calculation of advertising mode into our Excel sheet, but have not had time to do so yet. It is not so...

    Karl T.
    Hi Michael, No phones have been released yet with BLE support. We estimate that the first BLE phones will start shipping in the middle of 2011. As for the longer run, we expect adoption of Bluetooth 4.0 (BLE) to follow the same curve as earlier Bluetooth releases. You can get more information about...

  • Forum Post: Re: BTLE profiles?

    Karl T.
    Hi, Yes, there will be BLE profiles, just as there are BR/EDR profiles. The reason you aren't seeing a lot of information on them yet is that no profiles have yet been officially adopted, therefore they are not publically available yet. There are multiple profiles in the works, including Proximity...

  • Forum Post: Re: 2540 Transmit Power

    Karl T.
    Christian, It is actually also possible to send embedded HCI messages on the keyfob side as well, but as you say I don't think that is the main point here. I believe the default power setting is 0 dBm, so if you are seeing much less than this, then the problem is likely hardware related. You...

    Hi, Karl, I've already done a project with Zigbee in which one CC2531 USB Dongle was coordinator and ten CC2530EM were End Device and recently my client asked me to do this job with BLE (one CC2540 USB dongle and ten CC2540 keyfob). So you mentioned CC2540 cannot support multiple simultaneous...
