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?

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

Hi Marshed,

 

Do you have application log enabled at all that you can share with me? You can enable RTT logging, and use JLink RTT Viewer, if your serial port is in-use:

CONFIG_CONSOLE=y
CONFIG_RTT_CONSOLE=y
CONFIG_USE_SEGGER_RTT=y
# optional: CONFIG_LOG=y
CONFIG_UART_CONSOLE=n

 

Kind regards,

Håkon

Hi Håkon Alseth

which part of the do you want me to connect the RTT Viewer to NRF52840_XXAA or NRF9160_XXAA?

[Håkon Alseth]

Hi,

 

Since the nRF9160 is the host, you could start with looking at that one. As it gets stuck (not rebooting) - there's a high chance of seeing the behavior in the log trace.

 

Kind regards,

Håkon

I meant on the Thingy91, should I connect the RTT Viewer to the NRF52 side or the NRF91 side

[Håkon Alseth]

You should be able to spot something on both sides, but since you mention that it stops completely, I suspect the viewing the RTT log of the nRF9160 would give the "best indication" on what happens.

 

Cheers,

Håkon

I have checked both RTT Viewer to the NRF52 and to the NRF91 side but I do not receive anything from either.

Can you please attach the log?

Do you get any output at all?

 

Kind regards,

Håkon
