Dot-Examples Problems with dev Library

[Matt Brown]

Hi,

I appreciate it is the dev library and you may already know this but if you don’t my comments may help.

I built the OTA_EXAMPLE Dot-Examples with libxDot-dev-mbed5 and mbed-os-5.7.

It ran but the RTC wake-up doesn’t appear to be working. It says “sleeping 10s” or similar but doesn’t wake-up.

It is still running because pressing the button causes it to transmit.

It doesn’t make much difference to me at the moment, I can use libxDot-mbed5.

HTH,
Matt

Are you using sleep or deepsleep? When you say “doesn’t appear to be working” does that mean nothing is printing out on the debug port? Are you using sleep_wake_rtc_or_interrupt(deep_sleep);?

[Matt Brown]

static bool deep_sleep = false;

It says “sleeping 10s” but then nothing happens even if I wait much longer than 10 s; no debug messages and no activity on TTN.

If I press the button it transmits so the interrupt is working.

sleep_wake_rtc_or_interrupt(deep_sleep); yes.

I switched to the stable library (and mbed 5.4 and gcc 4.9) and it worked as I think you would expect, i.e. transmitted every 10 s.

I cannot reproduce this issue currently. I used the dev-lib, mbed-os-5.7.7 and gcc 6. Is there something else that you are doing differently than this?

[Matt Brown]

I think that’s what I was doing but it seems something must be different!

If/when I switch back to looking at the Dot-Examples I check what I was doing and let you know more details if it is still happening.

Exactly the same issue with mbed-os-5.7.7 and gcc 7.2.1 !
Keep us updated 😉

[Ryan Klaassen]

GCC 7.2.1 is not currently supported by mbed. It recommended to use GCC 6 with mbed-os-5.7.7. Have you tried GCC 6?

[Pierre-Marie Ancele]

I just tried and it worked now. That was the issue, thank you.
