CC2530: How to get the RSSI values from a module with CC2530 chip?

Hi Yikai,

Thank you for the reply. What should I change in the afBuildMSGIncoming to get the RSSI? Any documentation regarding this?

And how do I write this code onto the module?

Thanks

Yes. But I have this module which uses the TI CC2530 where I can only send the data using a Serial Monitor in Hex format as specified by the manufacturer.

I need to know how I can access the CC2530 chip from my computer to get the RSSI. Do I need to use any TI software like IAR Workbench or SmartRF to write this onto the chip?

Thanks

Yes

Hi Ryan,

Is there a way that I can have a look at the firmware that is already in my module? Because for now, I can only send and receive data as hex strings from a Serial Monitor.

Thanks

It's not feasible to guess what firmware is running on your module. However, if you know and can post what hex strings are sent and received, maybe we can guess accordingly.

These are the specified hex strings to send data from an end device and what is received at the coordinator.

This looks like proprietary command. You might need to contact who passes you the document.

Ok. Another question is can I get the RSSI value and PER from my module using SmartRF Studio 7 if I connect it through a CC debugger to my PC?

Thanks

Hi Yikai,

As you said the rssi is already defined in afBuildMSGIncoming. I need to know how I can call this function? I don't need to flash the firmware if it is already defined right? Can I use an arduino to call this function?

I'm pretty new to this and i'm not that well equipped with programming too. So your guidance is valuable.

Thank You

afBuildMSGIncoming is a C function in Z-Stack so you have to run Z-Stack example on your CC2530 to get the rssi in afBuildMSGIncoming.

How can I run it? Do I need to flash the hex file in the folder into the CC2530?

Hi Sehan,

You may be looking for the ZNP solution with a MT interface communicating through a host processor or Z-Tool, here is a recent similar thread.

Hi Ryan,

Well what I want to do is get the RSSI or LQI values from my CC2530. Currently, I just use a serial interface for sending hex strings in order to send/receive data and obtain other information(Setting PAN ID/Setting Channel etc). But the manufacturer has not specified any hex string/command to obtain the RSSI values.

I looked at the Z-stack 3.0 and as both of you suggested a C function is there which has defined the RSSI/LQI in AF. Now, I need to know how can I call this function or access the values. I'm aware of using the SmartRF Studio and obtaining the value but I do not have a CC debugger or a SmartRF development board with me right now. The modules I got come with Coordinator and Router firmware pre programmed and I expect it to have some version of Z-Stack running. Is there any way that I can use to access these RSSI values without going for a cc debugger? Can I use an arduino or Raspberry Pi? Or is it possible to do this with Z-tool?

Thank you

Sehan

Hi Sehan,

If you are using a serial interface with hex string commands then it is possible that you are already using the Monitor and Test Interface in which case you should be investigating use of the ZDO_MGMT_LQI_REQ command like I was leading Tessa through on the previously linked thread.  Otherwise you only have the commands available from the third party module and pre-programmed software, of which we cannot provide any further assistance.
