Also, for the unhandled promise, can you try changing characteristic.writeValue(val); to return ?characteristic.writeValue(val);? I think that'll be the problem - looks like all Espruino's docs need updating as none of them mentioned that.

I'll give it a try and update.

Update: after it disconnects on its own, I get the 3 LEDs of death followed by the red LED flashing once.

Hi Gordon,

I have a piece of code with a for loop (loops only 10 times to get lower, avg and upper bounds of light) inside an interval that outputs to the console - see print screen. It keeps working if it's not printing anything, but sometimes I need to either re-upload or switch off the bulb and then back on. You can also see that there is also a promise that wasn't caught which should have been already caught.

I had a try with some code with an interval of 30 seconds and coded some behaviour that allows some light tolerance so that it does not change back and forth all the time. I noticed that sensing light has some variance and this can cause issues. One odd behaviour I notice from the Puck is that when viewing console output after some time, console looping stops and I need to reconnect again to the puck. Although I find that what works well is to switch the AWOX bulb off and then back on. Is this a sync issue?

Ill copy my code so far here with some refactoring done.

I can definitely sympathise with you :)

My code so far is not terribly very clean; there are opportunities to refactor some functions to make it cleaner. Once it's squeaky clean and behaves as it should, I'll post it here.

Arduino/Raspberry pi enthusiast and tinkerer.

It's only doing this task, so no advertisement. It's weird. I ran it again, and I don't get it anymore.

As a precaution, I have set the interval to be 30 seconds. I'll let you know if it kicks up a fuss :)

HI Gordon,

So far, so good - the behaviour is much more stable, but I'm getting an "Out of memory while appending to array" warning as the interval keeps checking for light levels. Is there a way of doing this in JS or is it C level malloc stuff?

Hi Gordon,

I have tested this over the few days and what I observed is that if there is a timeout error which is caught (sometimes weirdly it doesn't get caught) it will get into a busy state and nothing will happen. What I have to do (manually) is switch the light bulb off from the mains and then back on again and it will resume operation.

Gordon,

Cheers for this, I have updated my puck and will give this a go. I'll let you know of any progress.

Hi Gordon,

I'll give this new code block a try.

Cheers.

Hi Gordon,

Thanks for the reply. I attach the code I am using using the light sensor and button sensor to result variables and switch the light to an off state. It might be that when len is too short as defined in the setInterval function, it kicks up the NRF error. I have tried longer len times and it resulted in crashes after several hours testing it.

I also added the catch after when writing to the smart bulb and it didn't catch it; the NRF error crept up and crashed the whole thing.

Hi,

I tried the code on the puck.js to be able to turn the AWOX smart light bulb on and off. After a few switches, a message pops up on my control with the following:

NRF ERROR 0x8 at ?:0

As soon as this message pops up, the puck lights up all 3 leds once, red flashes once and it goes dead until I reset it by holding the button and reinserting the battery.

I have tried my own code to be able to detect light and depending on light levels, it switches the bulb on or off; ideal if you have a pet at home and no one is home :) So I tried the basic code tutorial and I get the same problem. My puck.js has been updated with the latest firmware a few weeks ago.

I also get unhandled promise rejections which I can't catch using try catch blocks.

Any ideas about these issues?
