nRF52 & Fanstel EV-BT832F

[MikeDale]

all BT example projects from web hang down this call string bt_enable -> bt_settings_init -> settings_subsys_init

blinky example runs fine

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

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

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?

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.

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 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?
