Notecard stuck in sync for more than 20k seconds

gauteh · April 21, 2022, 7:48am

Hi,

I had a notecard that presumably had some issues connecting and it got stuck in sync requested for more than 20k seconds (almost 6 hours). Is it supposed to fail, or do I need to handle these hang-ups myself? Initiating a new hub.sync didn’t change the status. After power-cycling the modem immediately connects and syncs.

Firmware: 3.2.1.13982

Hi @gauteh
Could you describe some details of what led up to this failure (or how to maybe recreate the problem), and also the request / response that led you to conclude that the Notecard was stuck in a sync request ? (perhaps hub.sync.status ?)
Thank you
Sean

I don’t have much details. I attached a debugger to my host MCU and it logs the output of hub sync status which showed a value of more than 20k on requested field.

Probably not useful, but firmware:

github.com

gauteh/sfy/blob/main/sfy-buoy/src/note.rs#L199

      
        
            /// Send all available packages to the notecard.
            pub fn drain_queue(
                &mut self,
                queue: &mut heapless::spsc::Consumer<'static, AxlPacket, 32>,
                delay: &mut impl DelayMs<u16>,
            ) -> Result<usize, NoteError> {
                let mut sz = 0;
            
            
    while let Some(pck) = queue.peek() {
                    let sync_status = self.note.hub().sync_status(delay)?.wait(delay)?;
                    if sync_status.requested.is_some() {
                        defmt::warn!(
                            "notecard is syncing, not sending any data-packages until done: queue sz: {}",
                            queue.len()
                        );
                        return Ok(sz);
                    }
            
            
        let status = self.note.card().status(delay)?.wait(delay)?;
            
            
        if status.storage > 75 {

The firmware connects every 20 minutes. Was working fine for about 12 hours, then got stuck.

Thanks. Does your firmware log any of the responses ?
One other thing that might be helpful would be to set the environment variable _log to all in your project. The Notecard will then collect diagnostic information in the _log.qo notefile which might help to troubleshoot these types of problems after the fact.
