MCU was reset from time to time

[mark.zhang]

HI,

I have a product which scan for RFID card through NFC and Mobile Device through BLE after nRF52840 MCU was wakeup.

If I scan NFC and BLE scanning separately, everything was OK.

But, If I start BLE scanning first, do connect-discovery-exchange data in the event handle, then in a loop, I scan NFC for RFID card and check BLE state, nRF52840 will be reset from time to time.

May I scan NFC and BLE at same time, if yes, how to do it ?

Thanks,

Mark,

Hi Mark,

I have following suggests to help you debug this issue: 

1) Try to enable log and check the debug output from terminal, set "CONFIG_RESET_ON_FATAL_ERROR=n" to see the error cause when failure happens.

2) Try to set up a seperate Thread for NFC opetation since you have verifed they can work seperately. I feel not confident about the bloking logic in your while loop.  

Best regards,

Charlie

HI, Charlie: 

My project is a bare-metal firmware, should I convert the project to RTOS before I can use separate thread for BLE scanning ?  If yes, is that hard to convert from bare-metal to RTOS ? I'm a beginner on RTOS.

Thanks,

mark,

Hi Mark,

This is not hard since your porject is based on NCS/Zephyr.

Just learn about Thread usage and refer to the Zephyr sample. We also have DevAcademy course cover Zephyr RTOS basics.

HI, Charlie:

  I have read the document from the link you post. Now, I start to make a simple project on my custom board.

There is a PIC24 MCU and nRF52832 from MS50SFA on the board. They communicate through UART.

PIC_BMD1: Master RQ

PIC_BMD2: BMD RX

PIC_BMD3: BMD TX

PIC_BMD4: Slaver RQ

PIC will send a command packet to BMD every seconds. That will trigger BMD UART RX interrupt, BMD read the the data on RX, BMD will send a response packet to PIC after it receives a valid packet.

For RTOS project on nRF52832:

  Main tread will initialize system and hardware.

  After UART on BMD receive a valid packet, it will create a response packet and send to uart_tx_queue.

  A UART TX thread is created to send the response packet if it could be read from uart_tx_queue.

CONFIG_CONSOLE=n

If I delete the Uart0 definition from Overlay, compiling is fine. That overlay works fine on bare metal project.

Please help to take a look and tell me how to overlay with RTOS project.

Thanks, Mark,
