HI, Charlie:

Please forget the compiling issue, I fix it .

Thanks,

HI, Charlie:

I attach the zip file of my prdevzone.nordicsemi.com/.../pivot_5F00_bmd_5F00_03_2D00_RTOS.zipoject.

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.

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.

https://academy.nordicsemi.com/courses/nrf-connect-sdk-fundamentals/lessons/lesson-7-multithreaded-applications/topic/scheduler/

https://docs.nordicsemi.com/bundle/ncs-latest/page/zephyr/kernel/services/threads/index.html

Basic SynchronizationManipulate basic kernel synchronization primitives.
Basic thread manipulationSpawn multiple threads that blink LEDs and print information to the console.
Dining PhilosophersImplement a solution to the Dining Philosophers problem using Zephyr kernel services.
Dumb HTTP server (multi-threaded)Implement a simple HTTP server supporting simultaneous connections using BSD sockets.

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,

RE: MCU was reset from time to time

Charlie — Wed, 30 Oct 2024 09:28:54 GMT

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:

I use ncs v2.3.0

I used below loop to scan MobileID with BLE and RFID card with NFC:

scanStart();
while(1) {
if(gBleState == Ble_Nothing) {
gBleSequence = 1;
bMobileIDReady = false;
scanStart();
}

if((scanCard() > 0) || (bMobileIDReady == true)) {
if(gBleState == Ble_Scanning) {
scanStop();
} else if((gBleState == Ble_Connected) || (gBleState == Ble_Discoveried)) {
disconnect_from_mobile();
}

Delay_ms(100);
ConfirmationBeep();

if(gBleState == Ble_Completed) gBleState = Ble_Nothing;
}

During scan MobileID with BLE, I used as Central from the sample central_uart.

Mark,

Hi Mark,

Could you provide more informaiton about your program?

Like which SDK are you using, nRF5 SDK or NCS? which specific version?

It would be great if you can share a minimal sample that can reproduce this issue.

Best regards,

Charlie
