Can nR52810 support Zephyr HCI_UART?

[Hsu]

Hi Sir,

We design the nRF52810 in an embedded system and plans to use BlueZ to control the BLE device.

We can work with nRF52-DK through HCI_UART, so we also implement the HCI_UART for nRF52810, but we got link fail when tried to link w/ cell phone.

  

Some questions.

Q1. As check the folder, we found there is no nrf52810_pca10040.conf in the /zephyr/samples/bluetooth/hci_uart/boards,

Does it mean the nrf52810 not support in HCI_UART example?

 

 

Q2. I assume the 52810 can support example HCI_UART,

   Since we don't design the external 32K crystal, we config the 32k crystal set to RC, but we cannot get the link, even we change to synthesized.

Is it because the HCI_UART doesn't support nRF52810 natively? If not, is there something we miss in the Kconfig setting?

Q3. If Q2 is yes, we may change to nRF5232. For support DFU (MCUboot), what kind of setting we should enable in Kconfig?

Should we modify the flash size for MCUboot? and how? 

Or we have a detailed step to guide us to implement MCUboot?

Thank you.

Hi Hanyu, 

so we also implement the HCI_UART for nRF52810, but we got link fail when tried to link w/ cell phone.

Can you see the air sniffer log to see what went wrong for the link to fail? Did you use nRF52840 board settings on nRF52810? if so, that would make many things fail.

Does it mean the nrf52810 not support in HCI_UART example?

It looks that way. Seems like it is not officially supporting HCI_UART for nrf52810 yet. 

 For your other questions, I need to first understand if you are using our NordicConnectSDK or if you are using the Zephyr repo directly?

Hi Susheel,

I use the Nordic Connect SDK for this test, 

Thank you.
