    Dzuong Nguyen
    I'm having trouble erasing the CC2540 flash. I've just assembled my own CC2540 (256K) pcb using the keyfob layout as reference. I'm using a 3.3V regulator to power the CC2540 chip and also have the 32MHZ and 32KHZ crystals soldered on. The debug header pin assignments are almost exactly the...

  • Forum Post: CC2540 Communication between two Key Fobs

    Bobbie Gauna
    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...

    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...

    Jianfeng Lv
    Hi sir, I plan to use CC2540 in my project. However, unlike CC2530, I didn't find any information about registers that control RF part of CC2540 in the user's guide (swru191b), only status registers are available. Since the BLE stack is not open source, it means that both hardware and software...

    For a project that uses the CC2540, I need to perform ADC conversions periodically (every 4ms). It doesn't matter if there is some jitter in the time between conversions as long as it averages out to 4ms (+/- 10us). I could use one of the available timers to generate a periodic interrupt to achieve...
