Other Parts Discussed in Thread: Z-STACK, CC2538, , CC2530

Hello friends,

I am trying to configure a simple ZigBee network using ZNP method.

I have done the following.

1 - Build and Flash the unmodified ZNP program from Z-stack 3.1 with the following DEFINED SYMBOLS:

HAL_UART_USB
USB_SETUP_MAX_NUMBER_OF_INTERFACES=5
xHAL_SPI=TRUE
xHAL_UART=TRUE
BDB_FINDING_BINDING_CAPABILITY_ENABLED=0
TC_LINKKEY_JOIN
ewarm
CC2538_USE_ALTERNATE_INTERRUPT_MAP=1
CC2538ZNP
ZNP_ALT
xPOWER_SAVING
FEATURE_SYSTEM_STATS
FEATURE_RESET_MACRO
ZDNWKMGR_MIN_TRANSMISSIONS=0
MT_UART_DEFAULT_OVERFLOW=FALSE
ASSERT_RESET
FAKE_CRC_SHDW
ZCL_READ
ZCL_DISCOVER
ZCL_WRITE
ZCL_BASIC

2 - Using Z-Tool and following the tutorial in I also refer to the post and

3 - This is the screen shoot of my Z-Tool Commands.

As you can see, I cannot establish the network on my Coordinator (COM12) thus, Router (COM8) cannot join. I can't quite identify where is the problem despite trying many times. I am using Windows 10 FYI.

It would be very great if someone can help pointing me into the right direction.

Thank you very much,

Alex

Are you sure you set the same channel to router and coordinator.

Yes, I am. This is the screenshot of the upper portion of Coordinator commands. I highlighted the command setting channel for your convenience. I set both to Channel 11 and turn off secondary channel.

I don't know if this helps but the image I build from Z-stack 3.1 is CC2538ZNP-Debug.

I suggest you to setup sniffer to check what happens over the air.

Yikai,

For some reasons, I re-flash the image into the chip and it works. However, I see an abnormally, when I do Hard Reset from Z-tool, my chip doesn't automatically reconnect. I have to quit and reopen Z-tool for it to be able to scan for the device. Any thoughts on this?

Thanks,
Alex

What do you mean do Hard Reset from ZTool?

0 Hau Tran over 6 years ago in reply to YiKai Chen

Intellectual 615 points

I meant by sending the command SYS_RESET with option of hard reset.

How do you connect CC2538 to your PC?

0 Hau Tran over 6 years ago in reply to YiKai Chen

Intellectual 615 points

I connect directly into the board. Like the picture below.

0 YiKai Chen over 6 years ago in reply to Hau Tran

Guru 735455 points

Try to disconnect Smrtrf06 from your CC2538-CC2592EMK to test again.

Yikai,

I tried disconnect and perform hard reset on Router device.

1 - Write value of "3" into 0x0003 to clear NV after reset
2- performed SYS_RESET
-> The system freeze up and I had to restart Z-Tool
3- When it reopen, I try to read NV 0x0003 and the value of "2" is in it. [it should be 0 after SYS_RESET I believe]
4- I then set the channel and recommissioning and it is not working [again, it showed "no network"). This happen to me before, I need to reflash the a fresh ZNP image to fix it.

I think the problem of freezing up cause the problem. Do you have any thoughts on how to solve this problem?

Thanks,
Alex

If I remember correctly, Z-Stack ZNP only supports UART Interface and you shouldn’t be able to use CC2538 USB capability in ZNP. Do you implement this by yourself?

0 Hau Tran over 6 years ago in reply to YiKai Chen

Yikai,

I don't think I have found a new way to implemented this module. I also found this in the API documentation

Notice the "and thus causing the USB host to re-enumerate the device which can cause an open virtual serial port to hang.)"

However, before arriving at this way of connection, what I did was:

1 - Flashing the image of original ZNP onto the chip.

2- Connect it through SmartRF06 board while the pin on CC2538 is VDD-EB

-> I couldn't see the board on Z-tool.

3- I then switch to this method and Z-tool can scan for it.

How do you normally connect your ZigBee module?

Thanks,

Alex

Guru 735455 points

Yes, USB re-enumerated sometimes causes problem. I use CC2530 in most of my projects and always connect UART pins directly between HOST MCU and CC2530. I suggest you to do direct connection too.

Hi Yikai,

I wonder if you have a project repository you can share for a simple Host MCU + CC2530 interfacing? It would help me to learn the way to interface through sending messages through UART.

Thanks,
Alex

Yikai,

Do you know if I have to modify the EM Adapter BoosterPack if I am using TM4C123G?

Thanks,
Alex

I am not sure about this but I suppose you have to. You should check schematic to see what you need to modify.
