Hi,

The state of the wake pin only matters if you are using mDot::RTC_ALARM_OR_INTERRUPT. By the way, I’m using 2.0.17 and mDot::RTC_ALARM_OR_INTERRUPT in my app and it seems to be working fine.

Regards,
Javier

Hi,

If you are using dot->sleep(x, mDot::RTC_ALARM_OR_INTERRUPT), the wake pin has to be low before going to sleep. If it’s high, It won’t return from sleep.

Wake from RTC alarm and interrupt

Javier

Thanks for the information, Jason.
Best regards,

Sorry to bump this, but, is it possible to change the coding rate when using P2P?

If I try to do a soft reset I get:

[INFO] Backing up current firmware
[ERROR] backup_firmware: open failed
[ERROR] update_firmware: Failed to back up current firmware

Mike,

Sorry, what’s RFU? Yes I could fork the MBED repository and create a pull request with this change. Is there any chance that this modification gets applied to the main repository?

Thanks,
Javier

[Javier Pedrido]

Thanks, Leon, I also got it working connected to computer 🙂

[Javier Pedrido]

Thanks, Leo, I disconnected the MDK from the computer and connected it to a battery and It worked. I will try it connected to the computer with RTS active later (I don’t know how to do it 🙂 ).

Thanks again,
Javier

So, if I run the program without using the MDK and nothing attached to PA_0 will it wake from RTC? Is it possible to wake from deep sleep when attached to the MKD? I tried this and it didn’t wake up.

mDot* dot = mDot::getInstance();
dot->setLogLevel(mts::MTSLog::INFO_LEVEL);
logInfo(“version: %s”, dot->getId().c_str());

DigitalOut wake(PA_0);
logInfo(“Hola %d”, wake.read());
wake.write(0);
logInfo(“Hola %d”, wake.read());

dot->sleep(10, mDot::RTC_ALARM_OR_INTERRUPT);

[Javier Pedrido]

Leon, so it’s hardware problem? Javier

[Javier Pedrido]

Hi, if I run the following program without anything connected and starting with a powered off mdot:

`DigitalIn wake(PA_0);
DigitalIn other(PA_7);
mDot* dot = mDot::getInstance();
dot->setLogLevel(mts::MTSLog::INFO_LEVEL);
logInfo(“version: %s”, dot->getId().c_str());

while (true) {
logInfo(“Hola %d %d”, wake.read(), other.read());
osDelay(2000);
}`

I get:

[INFO] mDot Ready
[INFO] version: 2.0.6-2-ge3d307b
[INFO] Hola 1 0
[INFO] Hola 1 0
[INFO] Hola 1 0
[INFO] Hola 1 0

Is it ok that PA_0 is allways 1?

Javier

[Javier Pedrido]

Leon, but I dont have anything connected to mdots when I do the tests and they were powered off before the tests.

Mike,

I have two mDots, I’ve installed your program, unplugged them, plugged them again and both failed to wake up from RTC, they just printed one time:

[INFO] mDot Ready
[INFO] version: 2.0.6-1-g3959fe1
[INFO] entering deepsleep (standby) mode 00000037

The result of the other test was:

time 1451779203
time 1451779204
time 1451779205

I’m openning a support case.

[Javier Pedrido]

Mike, I will try that and I will let you know. Thanks for the help, Javier.

[Javier Pedrido]

Mike, did you manage to manage to reproduce this issue? Regards, Javier.

[Javier Pedrido]

FYI, If I use mDot::RTC_ALARM or mDot::INTERRUPT it works OK. The problem is just with mDot::RTC_ALARM_OR_INTERRUPT.

[Javier Pedrido]

Mike, I’m using a MDK.

[Javier Pedrido]

Is there some documentation on what versions should be used with mdot 2.0.3?
Javier

[Javier Pedrido]

Well, that combination broke p2p data transmission, I guess having wake on interrupt and rtc is not an option right now.

[Javier Pedrido]

FYI, reverting to mbed 116 and keeping rtos 117, mdot 2.0.3, fixed this problem.

[Javier Pedrido]

Thanks Andrew, but even if I remove that line still doesn’t wake up with RTC alarms.
