    Daimon2616
    Hi everybody, Which are the consequences of adding a PA/LNA, like CC2591, to the CC2431 location engine? Will it work? I know that the gain is controllable, so at least we must take that into consideration in software. Other problems?

    Hi, Interesting feedback :) With this on your displayed I am also sure the green LED is toggling too. Right? You will need to setup your IEEE address. Try to push the center of the joystick down and see what happens Hopefully this helps LPRF_Rocks

    Hi Alex, Yes, you can use the SmartRF04EB Evaluation Board as debugger for your CC2431 prototype, i.e. use as an in-circuit emulator with IAR EW8051 to debug your code. You will also be able to run our RF evaluation and radio configuration software called SmartRF Studio on your PC and use your prototype's...

(some of these are best suited for high-volume production). Here is a DIY alternative with open circuit...

    Thank you guys for the reply. I will check out the frequency on these boards and will come back to you asap, but can take a while as there are more important things up this week, but you WILL hear from me. THX again. Hope it is that, so that I have 2-3 boards more for the network. FLO

    Hi odel, the dongle in the eZ430 kits consists of two parts: the USB emulator board with USB connector (aka MSP-EZ430U), and a target board connected to it. The USB emulator can work as a debugger for the MSP430 on the target board. The debugger uses the 2-wire SPI-by-wire interface for the debugging...

    Hi Ashok, Does the LCD of the SmartRF04EB Evaluation Board work in other situations? E.g. if you try to turn off the EB, remove the CC243xEM, and power the EB back on -- does the LCD say "Chipcon SRF04EB No EM detected!"? (just as a test that the LCD works). The CC2430 and the CC2431 are...

    Hi. The CC243/31 has a built in sleep timer that can be used for WOR-like functionality in systems where other MCUs are involved. Wake On Radio is usually a term used for tranceivers that can wake the MCU on packet reception only. Regards, Kjetil

    Greetings: According to the comparison matrix in the link listed below, the CC2431 can do WOR. However, I could not find any data to confirm this in the CC2420 transceiver or the CC2430 which the CC2431 is besed on. I would appreciate a pointer to where I can find information about the WOR on the...

    Hi Ashok. So you are saying that it works fine with serial port communication between MSP430 <--> PC, and CC2431 <-->PC, but not between MSP430 <--> CC2431. Since you are not using the flow control, a problem with the UART CTS and RTS coupling should be out of the question. But could...

    We are having trouble debugging a custom cc2431 board using the SmartRF04EB. After connecting the prototype to the P14 SoC debug header the LCD on the SmartRF04EB turns off, which we assumed to mean that it has detected the board.
