Thank you Gordon. I have the following code:
function Timer() { [... some more code ...] setTimeout(Timer, 60000); E.kickWatchdog(); } E.enableWatchdog(10, false); setTimeout(Timer, 60000);This is supposed to run some code once per minute.
But the dog seems to never let it happen this way ... do I need to set the watchdog's timeout higher than my code timeout? The timeout function is not considered "idle" by the watchdog so I need to add this to the time I want to let the code do its thing? -
Thank you Gorden, this sounds perfect. Actually I could just set
E.enableWatchdog(10);And it will restart the whole thing whenever anything breaks / hangs longer than 10 seconds, right?
Does the dog take extra power? -
I have a puck running a simple script that is set to advertise every 2000 ms. There is a timeout set that checks battery every 10 minutes, attaches the value to the name of the device so I can see the status of puck's battery by using a BLE scanner on my phone.
I am not sure why but sometimes (after days) the advertising string doesn't change anymore (or keeps being empty), puck is still advertising, but the script is obviously not working anymore.
I believe this is because of some script error that breaks the 10 minutes routine.
So I would like to put the code in some "try-catch" loop that restarts the whole thing in case something odd happens. How to?
Thank you! -
Thanks, makes no difference unfortunately ... this is what the list looks like (filter set to 4C):

Hehe, after some more trying it works ... the IDE is sometimes a bit "unruly" ... thank you @fanoush!

Hi again,
I want my puck to wait a little longer before going into code that changes its name and advertising behaviour. But want it to wait only if a certain device is around (e.g. my iPhone).
So I tried to do a scan or a request ... but this never returns ANY names of the devices, even with higher timeouts and "active" being true?!
"namePrefix" does not make a difference when using findDevices – it just lists all, regardless of what I set. "namePrefix" does the opposite when using requestDevice – it never finds any, even if I just set one letter. Yes, I can see plenty of devices around using nRF-Connect including the ones I want the Puck to find.
This is what I have tried:NRF.findDevices(function(devices) { console.log(devices);}, {timeout : 5000, active : true, filters : [{ manufacturerData:{0x004c:{}} }] });--> puts out a rather large list, but without names
NRF.findDevices(function(devices) { console.log(devices);}, {timeout : 5000, active : true, filter : [{ namePrefix: 'S' }] });--> shows the same full list without names, although only two devices would fit.
NRF.requestDevice({timeout : 5000, active : true, filters : [{ namePrefix: 'S' }] });--> times out without any result
I have tried setting timeout to 10 or even 30 seconds – no difference. I must be doing something fundamentally wrong. Please advise.
Thank you again, I think I finally understand it – important note indeed!
