Hi @zhiguo77 ,
Can you disable fine grain TX sequencing as stated here in the driver API Guide.
Hi wassim，
Disable the effect is still the same, placed in the initialization,Do you also need to add this code to use PA and LNA normally?
Do you have PA and LNA development board？
Hi @zhiguo77 ,
After disabling fine grain TX sequencing, can you change the value highlighted in yellow below and write this value instead 0x0d20814:
You can do as following:
uint32_t data = 0x0d20814
dw->dwt_driver->dwt_ops->ioctl(dw, DWT_WRITE_REG, 0x110012, (void *)data);
Please let me know, if this helps
Thanks,
Wassim

Hi wassim，
Unfortunately, there’s still a problem. It didn’t work out. Is this a necessary connection for PA hardware?
GPIO4 is EXTPA, GPIO6 is EXTRXE.
But Our hardware is used：GPIO5 is EXTTXE，and GPIO6 is EXTRXE.
For this sdk, is this the reason why it does not work properly？Or what configuration of the sdk does this need to change ？
Best wish
Hi wassim，
Thank you for your strong support and help to answer my questions during this period of time. I have successfully opened PA/LNA, but the code you provided failed to be put in the initialization code of this SDK, so it needs to be put in dw3000_mcps_mcu.c file，and Put in the *static int reset(struct mcps802154_llhw llhw) function ，it is ok
EXTTXE toggling waveform

Hi wassim，
Thank you for your support. I have three questions when developing Apple apps:
1.The Nearby Interaction apply and Apple official apply What’s the difference?
2.Why do some Apple 12 phones not test well？What are the usual causes？
3.For the Nearby Interaction iPhone app,how to test the Angle? Is there an Angle measurement range requirement, beyond a certain Angle range there will be errors?
Is it the same as the measurement diagram below?

Hi @zhiguo77 !
- What Apple app do you refer to? I think most Apple NI examples were TWR between iOS devices, not third-party.
- Probably something to be answered by Apple, different models seem to have different antenna sets. This would be the main reason.
- What do you mean by “test the angle”? Yes, Apple limits the angle to a “line of sight”, according to:
Coach the user on range, orientation, and line of sight
When outside the line of sight direction field becomes nil and only distance is valid.
Kind regards!
