I haven't been able to run lte_ble_gateway for more than 2 days

[Marshed]

Hi, 

I am have programmed my Thingy 91 device with lte_ble_gateway program to collect data from 5 Bluetooth devices and send them to the cloud. This program runs fine, however it does not appear to continue to run for more than 2 days, after that the program just goes silent. No output, no error message no nothing. 

Can someone point me in the right direction please?

[Håkon Alseth]

Hi,

 

What are the traces coming from the thingy:91? You say it does not output anything, but where did it stop?

What makes the device function again, a reset of the nRF9160 or a power cycle of the full design?

 

Kind regards,

Håkon

Hi Håkon Alseth

I don't know what do you mean by traces, but I get no output at serial line, and no output at nRF Connect for Cloud. It simply stops doing what it is suppose to do. 

So far to get it to function again, I switch it off and on again manually. 

I hope this explains the problem. 

Regards 

Marshed

Can you please attach the log?

Do you get any output at all?

 

Kind regards,

Håkon

when it stop working, it looks like the log also stop working.

Hi,

 

Thank you for the logs. It looks like none of the nRF-devices are printing any fault reasons, which I believe might be due to a reset occurring, most likely on the nRF52-side.

JLinkRTT isn't always good at "reconnecting" the debugger interface is a reset has occurred, in those cases you have to manually disconnect from the RTT viewer, and connect again (F3 = shortcut for disconnect, F2 = shortcut for connect).

 

One flaw in the split-setup of nRF52 as a controller and nRF91 as a host is if the nRF52 resets. The host isn't then able to fully detect this (no mechanisms in the host layer to handle it), unfortunately.

 

If you only reset the nRF91 when this happens (let the switch set to nRF91, and issue nrfjprog --reset), does it recover fully afterwards?

 

Kind regards,

Håkon

Hi,

I tried to manually disconnect from the RTT viewer and connect again, however no additional log were observed.

I also tried to only reset the nRF91, the device recovered fully.

Hi,

This makes sense, as the nRF91 is running the host, and it will "reset" (a GPIO interrupt on the hci-controller that does a soft reset) the HCI controller on boot-up, as shown here in the board file for "nrf9160dk_nrf52840" board:

https://github.com/nrfconnect/sdk-zephyr/blob/master/boards/arm/nrf9160dk_nrf52840/board.c#L200-L209

 

I will report the instability issues you're seeing internally. In cases where the hci controller faults/hangs/resets, it is unfortunately a situation that isn't handled in the bt host at this time.

 

Kind regards,

Håkon

Hi, 

Thank you for your answer, however how do I proceed now? do I just wait, or their is some kind of work around?

Regards

Hi,

 

Unfortunately, the logs doesn't fully explain why it stops on your side, but its known that the host has missing implementation in case the hci-controller resets (or otherwise misbehave). If you are able to isolate/catch this issue in your firmware (host side), you can either use the watchdog or do a systemreset to recover. If you are able to get more detailed information out of the log or by debugging over SWD, please let me know.

 

Kind regards,

Håkon

Hi, 

I think the program stops after calling this function 

nrf_cloud_sensor_data_send(&in_data);

more specifically it hangs here 

return mqtt_publish(&nct.client, &publish);

any idea how to solve this?

[Håkon Alseth]

Hi,

 

Does it stop forever? Do you see many reconnects to nRF cloud throughout the session?

 

Kind regards,

Håkon
