CC2530: CC2530 with ZNP has no response for MT_ SYS_Commands

Part Number: CC2530
Other Parts Discussed in Thread: Z-STACK

I have a problem while running ZNPwith CC2530.

Firstly, pc can recive "FE 06 41 80 01 02 02 02 07 02 C1 " through serieal ports, and I can reset CC2530 by send SYS_RESET_REQ(FE 01 41 00 00 40).

But when I send other MT_SYS Commands(such as SYS_PING or SYS_VERSION), I get nothing as response.

I would suggest you to use ZTool to test this to see if it works first.

The ZTOLL shows " no device find"

Do you use TI CC2530DK to test this? Which Z-Stack version do you use? Do you build ZNP by yourself or you use prebuilt ZNP FW?

I don't use CC2530DK, just a Minimum System of CC2530，and I has tried ztack3.0.0 and zstack 3.0.2, build ZNP by myself.

If you use prebuilt CC2530ZNP-with-SBL.hex under C:\Texas Instruments\Z-Stack 3.0.2\Projects\zstack\ZNP\CC253x\dev, does it work?

It didn't work.I used serial port 0 without flow controller for communication. It maybe not match my hardare.

What pins do you use as ZNP UART on your HW?

Please make sure all instructions from Documents/API Z-STack ZNP Interface Specification.pdf are being followed. Flow control is enabled by default so this may be the first issue you are experiencing (can be disabled by defining ZNP_ALT). The Main pin configuration is used at a baud rate of 115200.
