Hi !

Now we use CC8531 + AIC3101 + CC2590 to make two boards, one master-slave board.TI samples can not be paired, and spectrum analyzer can observe the signal emission from the host.I don't know why. Please help,thanks

Hello,

Can you try substituting one of your custom boards with a known working PCB, perhaps a launchpad or a computer to see if the error is on the transmit side or the receive side? If you're able to verify that you're broadcasting with a spectrum analyzer, the issue may be that you aren't receiving correctly.

Best,

Nate

I only have my PCB now, when I use the main program, both of them send signals, it is estimated that the two PCB should be good, when I use "PurePath Wireless Commander" to input the command "SCAN", there is no signal scanning, I guess there is a reception problem

I will assign this to the hardware team to comment. In the meantime, I would recommend finding a way to verify your hardware. Did you match your antenna? Can you run a conducted measurement to rule out a radiated issue?

Best,

It is estimated that there should be no problem with the antenna. It is copied according to the file "SWRR079" of TI，

Thanks

Hi there,

Is this on TI HW or on your customer board? I suggest you request a design review first so we can ensure the HW is correct. You can do that here: https://www.ti.com/tool/SIMPLELINK-2-4GHZ-DESIGN-REVIEWS

Thanks,
