reading chip temperature sensor using zephyr controller

[Ahmed Samir]

Hi,

I'm using Zephyr controller instead of Nordic's Softdevice to use the DTM HCI feature in the Zephyr controller. Before switching to Zephyr controller, the application used to read the chip temperature using "BT_HCI_OP_VS_READ_CHIP_TEMP" HCI command. Once I switched to Zephyr controller, the "BT_HCI_OP_VS_READ_CHIP_TEMP" command return status error 0x01.

How do I read nRF53 temperature using Zephyr controller?

Hello Ahmed,

The Zephyr Controller doesn't contain a lot of features specific to certain chips/systems. Reading the chip temperature is one of such unsupported things.

If you want to read the nRF53 internal temperature with the Zephyr Controller, you will have to implement your own Vendor Specific (VS) HCI Command for the controller, following the details in the nRF5340 Product Specifications.
