Hi, can you tell us which Eval kit you bought?

26

To get back to the topic, can someone share what the expected configuration is for the UWBConfigData in the AccessorryConfigurationData struct? How does one retrieve it / generate it for the DW3000?

27

Hi, @Doe!

UWBConfigData is defined by Apple and is not open, the way to generate it is by using the NIQ library.
The niq_populate_accessory_uwb_config_data() function to be precise, like seen in send_accessory_config_data().

Best regards!

Hi @carlos.silva , thank you for your reply!

My problem is that the library is incompatible with esp32. Are there source files one could use to work with the DW3000 on ESP32?

Here is the output of objdump:

In archive libniq-m4-hfp-1.1.0.0.a:

niq.c.obj:     file format elf32-little
architecture: UNKNOWN!, flags 0x00000011:
HAS_RELOC, HAS_SYMS
start address 0x00000000

Hi @Doe !

Unfortunately, Qorvo only has these libraries available for ARM Cortex M4 and M33. It doesn’t appear that customers are using Xtensa chips, which makes it harder to wait for a release for this platform.

If you have to stick with the ESP32, the only solution I see is to put an intermediate and cheap ARM Cortex chip to implement UWB and NIQ and leave the connectivity (BLE/WiFi) on the ESP32 side.

Best regards!

Hi Carlos, do you know where i can find the NIQ and UWBSTACK lib for the Cortex M33 ? I’ve only found the dwt_uwb_driver lib for the M33.

Best Regards.
