Other Parts Discussed in Thread: CC2590, CC8530

Hello!

I'm using a CC8530 with the CC2590. Now I recieved my prototype and when I press the pairing button, the CC8530 seems to be reset itself. I can't find any problem in the configurator or shematic.

Does anybody know, why my CC8530 have such a strage behavior?

To me that sounds like a power supply issue, please verify the power supply rails the entire system and verify that is remains valid during TX and RX (higher current draw)

Hi,

I also think, that's a supply issue. But trying to supply the cc8530 with a power supply unit directly on the VCC input.. same behavior.

However, I'm on it and let you know, if I fing something.

Hello everyone,

It works now! However, I didn't assemble the two pullup resistors for the I²C and the audio codec for testing, because I wanted to test only the connection with external I²S signal. After adding these two resistors, it worked.

Cheers

Christoph
