About Zigbee Protocol

hello everyone.

who can tell me zigbee mesh network (mesh) routing protocol for that? Is it AODV?

thanks!!!

Hello,

Sombody Help me!

I have trouble, in application of CC1020.

When I change stage to Receive mode, then data signal is apeared on the DIO pin, eventhough I short Ant pin to Ground.

How is it possible?

I use 3 days to solve this problem, but I still not solve it.

My Init Sequence is,

  SetupCC1020PD();

 ResetCC1020();

 SetupCC1020All();

 WakeUpCC1020ToTX(0x47);

 CalibrateCC1020(0xA0);

 WakeUpCC1020ToRX(0x47);

 CalibrateCC1020(0xA0);

 SetupCC1020RX(0x47, 0xA0);

and the Config data is,

 0x0F,  // 0x01, INTERFACE

 0xFF,  // 0x02, RESET

 0x8F,  // 0x03, SEQUENCING

 0x3A,  // 0x04, FREQ_2A

 0x14,  // 0x05, FREQ_1A

 0x99,  // 0x06, FREQ_0A

 0x3A,  // 0x07, CLOCK_A

 0x3A,  // 0x08, FREQ_2B

 0x1F,  // 0x09, FREQ_1B

 0x45,  // 0x0A, FREQ_0B

 0x3A,  // 0x0B, CLOCK_B

 0x44,  // 0x0C, VCO

 0x51,  // 0x0D, MODEM

 0x9B,  // 0x0E, DEVIATION

 0xC6,  // 0x0F, AFC_CONTROL

 0x2F,  // 0x10, FILTER

 0x61,  // 0x11, VGA1

 0x55,  // 0x12, VGA2

 0x2f,  // 0x13, VGA3

 0x2d,  // 0x14, VGA4

 0x20,  // 0x15, LOCK

 0x78,  // 0x16, FRONTEND

 0x47,  // 0x17, ANALOG, RX=47/TX=47

 0x14,  // 0x18, BUFF_SWING

 0x22,  // 0x19, BUFF_CURRENT

 0xAE,  // 0x1A, PLL_BW

 0x34,  // 0x1B, CALIBRATE

 0xF0,  // 0x1C, PA_POWER

 0x00,  // 0x1D, MATCH

 0x00,  // 0x1E, PHASE_COMP

 0x00,  // 0x1F, GAIN_COMP

 0x00   // 0x20, POWERDOWN

I don't understand Why the Signal is appear on the DIO pin, without input signal.

Please somebody help me.

Thanks.

Hi,

the CC85XXDK contains the parts:

CC85XXEM

CC85XX-CC2590EM

is is possible to get/bye only the CC85XX-CC2590EM (or CC85XXEM) without the complete CC85XXDK

hello everyone.

We have a product using the CC2530.The SPI interface of CC2530 connection external FLASH. CC2530 is the SPI master. Use USART1 the alternative1. Hardware connections are as follows. Test found that there is no clock signal output P0.3. When modified to use USART0 of the alternative1, test P0.5, The CC2530 have clock output. Why? If the special requirements of IC, Why did not the notation description in the specification?

I tried to install the TRF7960 usb drivers unsuccessfully even following  the  SLOU1892C.

I'm running windows 7 ultimate.

The software is telling me this error: "invalid entry" even if I try to select the right com port.

I verified the com port and it's  seem ok.

I tried to have some answers on E2E community but nothing regarding my problem.

Could you help me on this issue?

hello,

My qüestion is about the cc2540 and its development kit. I have a doubt in the schematics design that appears in the document SWRR071. There are 2 inductors between the chip and the antena (ref. 251 and 261), that seem to have a value of 2.0nF in the schematic, but in the components boom they have a value of 2.2nF. Which is the correct value for this components the one that apperas in the schematic, the one that appears in the boom or both?

Thanks for the answer!

CC2591 bias inductor tolerance

AN068 (swra236a.pdf), Section 5.2.

I believe the capacitors should be in series with the resistors in the differential to single-ended realization.

Figure 5, and the whole section assumes the capacitors in shunt configuration.  Is this an error?

Hello everyone,

I purchased CC-6LOWPAN-DK-868 last week. I followed the steps according to CC-6LOWPAN-DK-868 Quick Start Guide and User's Guide. but in step 4(as mention in Quick start Guide) I can't see ipv6 router and only see the error message "No connection to /2001:0:0:0:0:0:11".

I can see "PHY: 1:00 - Link is Up - 100/Full" using hyperterminal and also found address 2001::22 under "Local Area Connection" when I use Dos command "netsh interface ipv6 show address".

Here my machine is installed Window 7 Enterprise.

Anybody, can you help me why my machine can't get ethernet connection with edge router.

I have a SimpliciTI project running well on CCS v4.Now when I migrate the project on CCSv5 I have some errors. It cannot resolve the symbol MAX_APP_PAYLOAD  located in one configuration file. Also when I attempt to change some parameter in the Porject properties Window, the system tells me to look for details of an error in the project.log file.

I have the following message in this file

: !ERROR: Build-tools MSP430v3.2.1, or any version compatible with it, is not currently installed! Please migrate the project to one of the supported build-tools first.

Could someone help me to resolve this problem.
