  • Forum Post: HostTestApp on CC2540EB -- invalid Profile Role??

    Miles Guidon
    I have The CC2540EB configuration of HostTestApp running on the CC2540 key fob that comes with the TI mini dev kit. I have a PIC24 MCU providing UART HCI to the key fob, and I am trying to send the three GAP commands to make the device discoverable by the USB dongle, using BTool during a "Scan"...

    Kjetil
    Hi. If you can't use the internal one then Texas Instruments has a whole range of temperature sensors: http://focus.ti.com/analog/docs/sensorshome.tsp?familyId=353&contentType=4 I'm sure you can find one suitable for your needs. Regards, Kjetil

    Karl T.
    Mike, On question 1), yes, you should connect your external 2.2V reference to AIN7. Make sure to select AIN7 as a reference rather than the internal one (ADCON2). Karl

  • Forum Post: CC2540 Detailed Data Sheet

    Kay Reiche
    The data sheet for the CC2430 has 212 pages, including a bit-by-bit description of all registers and much more. That one I found for the CC2540 has 33 pages and does include almost nothing. Is there any detailed data sheet available for the CC2540?

    Karl T.
    Hi Christopher, There are a lot of different crystals that can be used, with different size/cost trade-offs. In general, the most important things to look for is accuracy (a certain number of ppm over a certain temperature range), and load capacitance. As noted in the data sheet, we recommend the...

    Thanks, Karl. I've since learned that some limited BLE support has made its way into the Android source tree (or at least into the BlueZ source tree). So, for now, I am going to bridge from an emulated Android phone to the CC2540 kit USB dongle. As soon as it's feasible, I might try to put...

    Hi Team, I have two SDK for CC2540 and I am wondering if there's a way to set up one as a host and the other as a slave. If so, can I also use the test pins to read data off the master keyfob? My plan is to use the proximity code to communicate between different devices using the keyfob reference...
