Other Parts Discussed in Thread: CC2592,
Hello.
We develop a custom board with the cc2652R and the cc2592 PA, we want to use it as a coordinator in a Zigbee network. We make a prototype run and now we are testing it. For testing purposes we use the zc_zone example. In the TI development board we achieved the goal of comissioning some other devices (third party sensors) sucessfully and we can receive the sensor data. When we adapt and test the same software on the custom hardware the software works fine, no errors show when we debug it. The problem is that, some times it works fine (comissioning and receiving sensor data), and some times it doesen't work at all. We have a Zigbee sniffer and when it doesent work, seems like the device can send packages but when a sensor sends it data or is in the joining the network process our hardwere rf doesent receive nothing.
We discover that putting our finger over the cc2652 seem to make it work everytime, and it stays working some time after we retire the finger, but some time after it stops working.
We checked different boards and the problem is the same. Obviously is a hardware problem, but when it works, it works really good (even without the finger on top of the IC). We even tried some bluetooth software on it (simple_perihperal), and it works prefect all the time. At this point we are a little bit lost, do you have any sugestion of what can be causing it or what we can look for in the hardware to solve it?
Thanks.
