nRF52 & Fanstel EV-BT832F

Ok, so now you're able to get it advertising? Do you see the board advertising in the nRF Connect mobile app?

The log statements goes out on the serial terminal, if you're using the nRF52832 development kit then you should see the log output on the same virtual port that the Zephyr boot log is printed on.

tried again and your right

- my deleting and reinstalling all Nordic stuff seems to have gotten me past the fail at bt_enable(). Just stepped past in debugger.

Where does the LOG_INF statement log to - I see no results in my terminal window

Do you have an android phone that you can test this with? If the board is blinking then it usually indicates that the board is advertising. Please try to scan the device running unmodified peripheral_uart on the DK, and use the nRF Connect mobile to scan for the advertisement.

Also, make sure that you aren't running the sample in debug mode with breakpoints set.

One more thing, the gatt status error code, did you read this from the android app or from the log output from the nRF5340?

Still fails at the same place.

I deleted all nordic apps and directory's from my windows 11 pc.

Reinstalled - no change

Tried older toolchain - no change

it's not advertising - my android terminal emulator remembered it from the factory ship pairing

Hi Michael,

Ok, I'm assuming that you're able to get the device advertising since you're trying to connect to it from the android phone, and that the device doesn't reset at bt_enable() as before. What application are you using on your android phone, is it nRF Connect mobile app or are you still testing with the Fanstel mobile apps? What phone are you using?

[quote user="MikeDale"]Not sure what NCS is[/quote]

It stands for nRF Connect SDK (NCS), what NCS version are you using? GATT Status 62 (BLE_HCI_CONN_FAILED_TO_BE_ESTABLISHED) is a general error code which can be caused by multiple reasons such as the peer not responding to the connection request.

I'm interested in reading log from the "output from USB" when the program asserts.

Looking at your debug log, it looks like you either put a breakpoint at the start of main or that you don't start the execution of the program after starting the debugger. Could you just flash the program without starting debugger and share the log output from the USB when it asserts?

Please set CONFIG_RESET_ON_FATAL_ERROR=n in the project config as well.

Hi,

Which NCS version are you using?

Can you add CONFIG_RESET_ON_FATAL_ERROR=n to your project config file, this will prevent the program from resetting when it hits an error. The serial log should specify the error causing the program to assert. Can you share the log output?

Communicates fine with the UART/USB port.

Hi Mike,

Could you upload the files as a zip here. Either just drag and drop it in the reply box, or use insert->Image/video/file.

I'm a bit confused, you have a Fanstel EV-BT832F board and a custom board that has a nRF52832, is this correct?

And you're not able to run any of our BLE samples on either the Fanstel board or your custom board without it asserting?

Can you share the schematic for your custom board?

Jared

It's not the EV-BT832 board. The Fanstel hex demos that I've downloaded work fine communicating with Fanstel Anroid apps.

Something must be wrong during the build process.

google link to the build folder. "visual studio setup.pdf" contains screen clips during the build process. Other pdfs are Fanstel's documents.

https://drive.google.com/drive/folders/1MifQ6Ty9BDXUtY9lDnEPfiK0oXa_69Ix?usp=share_link

Update Feb 4- also fails using the nRF52:

Talked to Nordic's GENE RITTENHOUSE | Rocky Mountain Regional Sales Manager, Americas. He suggested disconnecting the Fastel board and running the app on the nRF52 development kit. Did that.

Same results on where it hangs up (bt_enable). It is able to printk to the USB port. The app is resetting every 1/2 sec and sending the reset ASCII message to the USB.

Hello World example runs fine.

Thanks for the help

Mike

Hi,

Can you share the build folder and specify the full part number and share the datasheet of the external 32 kHz crystal that you're using?

regards

Jared

RE: nRF52 & Fanstel EV-BT832F

MikeDale — Thu, 02 Feb 2023 15:09:54 GMT

the Fanstel EV-BT832F does have a 32k xtal installed on P000 and P001.

I put the two lines of code into files: prj.conf & prj_minimal.conf

no change

RE: nRF52 & Fanstel EV-BT832F

Jared — Thu, 02 Feb 2023 08:37:51 GMT

Hi Michael,

Do you have an external low frequency crystal on your custom board?

If not, then you have to configure the board to use the internal RC oscillator instead.

Add this to your project config file:

CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y
CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC_CALIBRATION=y
