CC1101 communicating couple does not see an other CC1101 communicating couple: same register, same baloon and matching parts minor layout difference

I relaized two a product with same cc1101 communication terminal and two different uc MSP430G2553 and MSP430F2274 for different purpouses. a couple of cc1101+ msp430Gs553 runs communicating without problems, the other couple using cc1101+msp430f2274 runs same software and register setting for the radio part and communicate without problems.

When I try to put in connection a cc1101+2553 with a msp430+2274 they does not see each other.

I attach cc1101 register here asking if the error is in register configuration

TI Z-Stack 122

zcl_general.h

/*

Can someone explain how to use this? Because unlike COMMAND_ONOFF_TOGGLE etc, I cannot define for COMMAND_ON_DURATION.

Is this correct way to use it?

zclGeneral_SendOnOff_CmdOnDuration( SAMPLESW_ENDPOINT, &zclSampleSw_DstAddr, 3000, FALSE, 0 ); //off after 3secs?

Possibility of 6lowpan implementation with cc2530dk with contiki 2.7 OS. Recently I purchase cc2530dk for zigbee mesh implementation.Now I want to use use this board for 6lowpan.I studied some blogs related to 6lowpan with cc2530dk.They didn't face a problem with connectivity of cc2530dk with contiki,but I have a problem with this board and my OS.....

1. how can I connect board with contiki OS for testing 6lowpan applications..i connected through console using RS-232 cable but no response from board.Again I connected through USB but in DEVICE manager its not showing any comport for cc2530dk.....

  Is there any alternative steps to implement 6lowpan using cc2530dk..

cc430f5137 reference design for 433 MHz

Hi,

  I want to upgrade fromCC1101-MSP430F5529 to CC430F5137 based platform for miniaturization. CC1101EMK433 module was used along with the MSP430 launchpad in the former case and the carrier frequency was programmed for MedRadio Band (401-406 MHz). Unfortunately, eval. module for CC430 at 433MHz is not available. To design a custom PCB for CC430, can the reference design of CC1101 at 433 MHz be used for designing the rf matching circuits?  Will this still allow me to program the radio in the desired frequency range? It would be of great help if someone can provide the BOM and reference design files for CC430F5137 that can operate at 401-406 MHz.

Thanks

How to enable desired cJTAG OScan mode on CC26xx device

January 27, 2016, 7:26 am

I would like to know necessary steps to get the CC2650 device in OScan1 cJTAG mode.

I have followed the TRM to play the JTAG sequence as described but the device doesn't respond on the third OScan1 clock.
TMS seems to stay in 3state. OScan1 TDO stays HIGH if previous OScan1 serialized TMS is HIGH and line rises slowly (due to TMS line pull up) if previous OScan1 TMS is LOW.

After powering on the device I start with two zero bit scans followed by single data scan to enter command mode.
Then CP0 is set to 3(STFMT) with 3 Shift-DRs and CP1 to 9(OSCAN1) with 9 Shift-DRs.
Command is finalized with going through Run-Test/Idle and command mode exited with IR scan.

Are there other step needed to put the device in OSCAN1 mode with custom hardware connected to TCK, TMS and GND?

XDS100v3 works in two pin mode so the part is functional.

Hi,

I am using  NXP MKW2 radio but need a range extender,.I was looking at the the CC2590 and theCC2592 but I couldn't tell if there was a impedance mismatch between two devices.  The NXP datasheet is here - http://cache.nxp.com/files/rf_if/doc/data_sheet/MKW2xDxxx.pdf?pspll=1

Table 47 shows the RF port impedance - but I wan;t sure if that would be a match for the range extenders - can you help?

TrxEB with a CC1101EM. Baud rate issue

February 1, 2016, 11:11 am

I have two TrxEB boards each with a CC1101EM module attached. I can talk to both TrxEB boards and the modules with my PC and they talk to each other using the Generic 868MHz settings with data rates of 1.2kBaud and 2.4kBaud. (GFSK)  If I choose any higher data rates, the TrxEB boards no longer communicate with each other.4.8kBaud show some reception, though none of the receive packets are good.

Both both boards have the same defaults, I enable receiving before starting the transmit, and this works all the time on 1.2kBaud and 2.4kBaud with no error. I do need to up the data rates for the application I'm working on. Is there any area I should concentrate on to see if the baud rates can be raised?

  Thanks for any help with this!

Need info on OSAL timer

February 2, 2016, 12:10 pm

Which hardware timer does OSAL timer function use on CC2530?

If I set a timer of e.g. 1 hour, will the processor sleep  in PM2 / PM3 for 1 hour, or will it wake up several times during this interval?

I am assuming no other activity / events / interrupts except for the task I have to do at 1 hour intervals. 

I am using Z-Stack Mesh 1.0.0     cc2530EB. 

I am asking this because it is critical from the point of view of absolute minimum power consumption. If the processor frequently wakes  up to count the milliseconds and seconds, then it will greatly reduce the battery life. So I need to know whether the processor is really sleeping in PM2 / 3 for a long period. 

I am afraid that instead of sleeping for a long period, the processor does wake up frequently, otherwise in what other way could it allow us to set several different timers of different intervals?

CC1101 Slave Out not going high when CSn is pulled high

February 3, 2016, 4:42 am

Hello,

I am working on a project which utilizes a CC1101 interfaced with an STM32F407 microcontroller. I connected a STM32F4xx Discovery Board with the CC1101 evaluation board and verified it's operation. But on a custom PCB, which used the layout of the CC1101 evaluation board, it refuses to respond. I cross verified the voltages at each pin on an evaluation board and on the custom board. They are almost the same.

When I pull the CSn pin high, I expect the Slave Out line to go high (as shown in the timing diagrams in the Power On Reset procedure), but the pin shows a constant zero voltage. Can anybody give any suggestions as to what might be the problem and how I can fix it?


Thank you very much.

hi,

i need to know, is it possible output power lower than -23dBm?

due to CC2540's datasheet only has typical value, i want to know, if i setting the output power to minimum recommended setting, will the result lower than -23dBm?

i don't care how low it will be, i just want to know will it be lower than -23dBm? Thank you.

CC1310 + CC1190 - 915 mhz design

Hi, i need advice to succeed in the design of cc1310 + cc1190 -915MHz, as i can't wait for the reference design to be released.

On others questions i found that the design would be similar to cc1120+cc1190, but cc1120 has different rf-pins, so some modification are needed.

My idea is to use the beginning of the RF path( discrete balun ) that is in the reference design (CC13xxEM-7XD-7793_schematic_1_3_3.pdf), and above the SAW filter, exactly as cc1120+cc1190 design.

as in this schematic.

Could this work?
I appreciate any advice or suggestion,

Thanks, 
Pablo

1 of 2 CC1111EMK868-915's Solid red light in CC-Debugger, other work fine.

I have a new CC Debugger and 2 new CC1111EMK868-915's. The first one simply gives a solid red light in the Debugger and is not recognized no matter what I tried to do. I tested it on a second CC Debugger and same issue. The second CC1111EMK868-915 gave the green light and was able to be flashed without issue from the same CC Debugger with same connectors.

I it seems like there is a problem with the CC1111EMK868-915 but I am not sure how to debug or determine if it is a dud. Visually I don't see any problems and it is new (has not previously been flashed). 

I have read through the other threads on this subject, but i was unable to get anything to work. Once I tested both on a second cc debugger and a second board on this debugger I think I can rule out any debugger firmware issues.
