  • Forum Post: Modifying MAC radio on+CCA+TX process

    colinb
    Hi, We are hoping to use the CC2430 for the next generation of our product, but are concerned that the TIMAC library won't give us enough control over a particularly critical aspect of our design--primarily since some of the most important parts of TIMAC are in the binary-only propietary library...

  • Forum Post: TIMAC source code

    joma6528
    Is there any way of getting access to the full TIMAC source code. My app requires CCA, retransmit on error with random back-off, AES encryption etc. What I don't need is the OSAL or the formation of networks (co-ordinators, association etc). In other words nearly all of it. The BasicRF...

  • Forum Post: CC1100 and Clear-Channel assessement based on RSSI

    JMR1972
    Hi all, I'm in the throws of of getting some radio activity going. Part of the protocol is to check for a clear channel before transmitting anything. I've configured GDO0 to be my CCA pin. The CCA is configure to be when RSSI is below threshold. The problem I'm having is that my CCA...

  • Forum Post: Re: CC1110 Rx / Tx switching

    DanieleCucchi
    Hi, I implemented CCA in this way: 1) Strobe RX with timeout termination enabled and start a timer with interrupt enabled (RX is necessary if you want to listen before talk, I use the timer to make a convenient delay). Then the application stay in a while cycle checking MARCSTATE == RX; 2) When...

    Niket Shah
    Hello all, I am developing a propriatary driver software for CC430 (915 Mhz base freq) using RF1A.c as a basic framework. For radio Initialization parameters, I am using SmartRFStudio generated Register Values. However, for channel selection, I first want to scan some channels (say from Channel...

    Philipp Troebner
    Hi there, we currently developing a device with the CC1101 as transceiver where the listen before talk routine (LBT) is neccessary. Looking in the CC1101 datasheet one can see, that there is the support for clear channel assessment (CCA), which we want to use for our LBT- routine. It is said, that...

    Tan Huisheng
    Hi I'm trying to use CCA, the current CCA state is viewable on GOD0 (IOCFGx.GDO0_CFG=0x09). Most of the time the CCA is OK, But when I insert the Debugger ICD3(Microchip MCU Deubgger) or Serial line(USART), the GOD0 output a lot of noise which can be display by oscilloscope. I don't...

    I have two CC1100 nodes spaced some distance apart on my desk, transmitting at 315 MHz at -10 dBm, with 433 MHz antennas. I don't believe saturation could be an issue because of the low output power and mismatched antennas. I have also tried the same setup with CC1101 radios with the same results...

    Hi. I'm testing a system that uses the SimpliciTI stack on CC430 and CC1101+MSP430F24xx based devices in the 433MHz band. The implemented system is a network of unconnected nodes, all end-devices, where the majority of the devices, let's call them tags, wake-up periodicaly with a period defined...

    Fred Schader
    Hello I have a system where a CC2510 receiver wakes up and listens for a few mS every second. When a sensor wants to communicate with the receiver it sends a small packet over and over for a full second. This system works well and we have deployed tens of thousands of them. In a new variant of the...
