HCI_UART on THINGY:91

Dear, 

I am trying to test BLE on the THINGY:91. 

Follow the Q&A for "Introduction to Nordic THINGY:91" webinar, Q12  of @Petter Myhre

I tried with Zephyr HCI UART example 

But, I couldn't find nrf52840_pca20035.overlay. From the schematic of THINGY:91, I created file: nrf52840_pca20035.overlay

Then, 

use nRF91 DK to program for THINGY:91 (SW SELECT to nRF52) 

After programming, I couldn't find any serial port to connect to THINGY:91 anymore!!!

I tried to restart my computer and reset thingy:91, but the same problem. 

Did I do something wrong? How can I fix it?

Thanks so much 

Best Regards, 

Hoang Nguyen

  • And, on the schematic of THINGY:91: MCU_IF: 

    and, I check dts files:

    nrf91: ncs_v1.0.0_joakim\nrf\boards\arm\nrf9160_pca20035\nrf9160_pca20035_common.dts#L165

    nrf52840:  ncs_v1.0.0_joakim\nrf\boards\arm\nrf52840_pca20035\nrf52840_pca20035.dts#L39

    UART0_nRF91 and UART0_nRF52 are matching ,

    but 

    UART1_nRF91 and UART1_nRF52: 

    rx-pin = <32>;  but on the schematic nRF52_P1.00 

    Is it correct ? I am confusing here.

    Thanks, 

    BR,

  • Hi Hoang,

    From the nrf52840 pin config, you can see that p0.00 --> p0.31 and p1.00-->p1.15.
    That means the following:

    p0.30 ==> <30>

    p0.31 ==> <31>

    p1.00 ==> <32>

    p1.01 ==> <33>


    Here is the default boardcontroller on the Thingy91:
     thingy91_nrf52_usb_v0.2.2.hex

  • Thank

     about the pin p1.00 ==> <32>, I got it,

    and: 

    After programming, I couldn't find any serial port to connect to THINGY:91 anymore!!!

    I could program, and it works normal, but I couldn't find the serial port to see the log file anymore. 

    Do you have any suggestion to fix this problem? 

    Thanks, 

    BR,

  • Hello,

    Also trying to get the lte gateway working on the Thingy:91.
