@wolfgangr Are you still on this idea ? I'm currently working on that

@wolfgangr I'm currently using an ESP32 and trying to optimize TOF. Currently I'm : Sending a RTS frame Getting the internal CPU counter value Listening for CTS Getting the internal...

I totally agree with you on the fact that flashing it with some custom firmware could probably allow TOF. I can't remember where but I saw espressif talking about implementing...

I think Espressif probbaly got inspiration from already existing open-source project but for sure they modified it a lot. They took particular care to not divulge their IP (the possible...

I used different length with wpan-ping, all with the same result. Also tried raw socket with no more success. I verified if spi was working at all, and basic commands...

I'm not exactly sure which exact information you are expecting, I hope it is one of those : The kernel used is the Linux 4.11 Fearless Coyote, driver spi-imx. The...

The moment it fails is in "dw1000_tx()" when calling "spi_async()" Exact line is : " > if ((rc = spi_async(dw->spi, &tx->data)) != 0) > goto err_spi; Right before the call...

I followed the path up the the EINVAL and it originates from "spi_map_buf()" in spi.c The responsible code is : ``` #ifdef CONFIG_HAS_DMA static int spi_map_buf(struct spi_controller *ctlr, struct device...
