Hello,
I was implemented the TWR case with DWM3000 module. Now, I want to do the same thing on the ic DW3120 with single channel(one antenna) first. There are my problems below:
Is dw3000 api work on dw3120? The device id of dw3120 is deca0314. In the dw3000_device_api.h. Supported device are deca0302 and deca0312.
When I bypass the ckeck of device ID. I got failed in the procedure dwt_configure.
Check procedures:
---1. dwt_checkidlerc()
---2. dwt_initialise(DWT_DW_INIT) == DWT_ERROR
------ in the end of step 2. I got message "XTRIM OTP READ FAIL"
---3. dwt_configure(&config)
---4. Complete the above steps. The RF did't open. dwt_starttx(DWT_START_TX_IMMEDIATE | DWT_RESPONSE_EXPECTED);
