Other Parts Discussed in Thread: CC2538, CC2530

Team,

One of my customers planning to use CC2538 along with the Wilink8. In the following appnote there are details connection between Wilink and CC2530.

(http://www.ti.com/lit/ug/swru437/swru437.pdf

Can CC2538 be used with Wilink8 ? If yes what are the lines to be used from CC2538 ?

Best Regards,

The RF part of CC2538 and CC2530 are similar. The difference is on MCU. CC2538 is cortex-M3 and CC2530 is 8051. The connection in the application note uses UART so you can connect CC2538 UART pins to Wilink8.

Hi,

Actually, these lines are not UART... they are proprietary lines, which carry real-time information about the RF state of the WiFi and the ZigBee. The algorithm should work similarly on CC2538 as it works on CC2530, because as YK said, they both share a similar radio. This being said, it is important to note that this coex algorithm was only tested and verified on CC2530.

Hello OD/YiKai Chen,
Can I get details of the software implemented on CC2530/Wilink for implementing this... I couldn't get a detailed explanation how this has been written. I will guide customer to use the same for their wilink + CC2538 Setup.
