CC2538: Can one CC2538 network with 100 zigbee end devices?

Thanks for your reply.

Thanks, I'm more confident.

I can use Z-Stack 3.0.2.
But I have no way of knowing the version of my customer's zigbee device.

If your connecting devices are based on Zigbee 3.0 ior ZHA 1.2, there is no problem to connect. However, you still have to know how frequently those device would send packets to evaluate the possibility.

Hi Ryan

In addition,

1、If I develope router & coodinate function in one cc2538.

2、And supports OTA upgrade firmware.

3、Then add a few instructions to control the transmission of data.
      (Need to support the standard profile of Accelerometer Sensor)

According to your experience.

Is the code size of cc2538 sufficient for such a requirement?

Thanks, 

Preliminary understanding.

My customer may need to support acceleration sensing.

Is it suitable to use the GenericApp sample code in the sdk?

Or is there something else more suitable?

Thanks a lot.

Got it.

Very thanks for your help.

By the way, CC2538 is actually not recommend as new design and I would suggest you to use CC2652R instead of CC2538 for your new design.

Thanks for reminding.

But currently there is only one customer in this case who needs.

It is very possible that I will be asked to directly modify the current structure. (Z-Stack 1.2.2a)

To achieve the fastest demo for my customer.

Is your product providing the updated image to other devices in the network through OTA, or accepting new image updates itself?  Either way you should follow the Z-Stack Home 1.2.2a.44539\Documents\Z-Stack OTA Upgrade User's Guide.pdf for either resourcing the OTA server project or adding client functionality, respectively.  Then you will also need to be adding ZCL clusters/attributes for the accelerometer since this is not already utilized in a default Z-Stack example.

Thanks for your many help.

The existing fw already has an ota architecture that can be updated itself.

CC2538 is used as client.

My device --> PCIE iface --> upgrade two CC2538

Just modify it to one CC2538.

Hi Ryan

May I ask if one CC2538 chip can combine router and coordinate at the same time.

Why do many people choose two CC2538 chips? (One Chip：Router, One Chip：Coodinate)

Are there any limitations to one chip?

Number of terminal devices in the network?
reaction speed?
or others?

Hi YiKai

I can't open this website.

If you are from China, you have to use VPN to access the link.

Sorry.

Are there any other links??

I work in the company.

Sorry, I want to confirm.

My architecture：
My gateway <----> (uart)cc2538(coordinator) <----> Approximately 50 to 80 zigbee end device( CC2538 or CC2650)

Because there is no IAR license, I can only use Z-Stack 1.2.2a.

So I need to open the following project：
1、CC2538：SampleLight (coordinator.bin)   <--- Don’t need  Router?
2、End device：CC2538 SampleSwitch (EndDevice.bin)   <--- CC2650：I didn't see for cc2650 in zstack 1.2.2a.

1.Since your gateway connects to CC2538 to act as coordinator, I suppose you should use ZNP running on CC2538 instead of SampleLight.

2.If you install Z-Stack home 1.2.2a, Z-Stack home for CC2650 can be found under C:\ti\simplelink\zstack_home_1_02_02a_44539

Thanks, great help.

So I should use "CC2538-SBL" project in ZNP on the gateway coordinator.

Then use "CC2538 or CC2650(End Device - Pro)" project from ZNP on the end device. 

I remember you don't need "CC2538-SBL" project in ZNP. For end device, you can use SoC mode (SampleLight or GenericApp example) instead of ZNP.

Very thanks.

I will study it immediately

Gateway coordinate："CC2538" in ZNP

End device：CC2538(SampleLight) or CC2650(SensorTag)
