I’ve just received my BrewSpark, and was trying to set up a couple of temperature probes. Now whenever I power up the Spark it beeps at me endlessly and erratically, - it almost sounds like a '90s modem.
Is there a way to turn off beeping, or will I need to reset the Spark?
I’m also having this problem. The beeping seems to change in tone and frequency when I send signals to the BrewPi via the webapp. Any word on what may be causing this issue? I know the USB ports it is connected to are 3.0. When I plug into the 2.0, the screen won’t even come on.
Can you try powering it with a USB power supply for a phone? When this problem occurred in the past, it was caused by the PC sending random data to the Spark. The alarm can be turned on and off by sending A/a, which might be what happens here.
The Spark runs the control algorithm autonomously. In fridge constant mode or beer constant mode, it does not need the web server. Temperature profiles are managed by the pi though, it is just like beer constant mode, but the pi sends setpoint updates.
I suspect your PC is sending an ‘a’ over serial, which enables the alarm. I don’t know why that happens. Maybe due to a bad USB cable or the board is not getting enough power, which caused data corruption?
Can you can try powering the board with a 12V power supply or using a better/shorter USB cable?
Hi, I have tried a few USB cables and they all were the same - when the USB isn;t connected and its only powered by the adapter, its silent. BUt as soon as you plug in he USB its starts beeping again. BTW, I’m using a PC running Linux.
Is there a command I can use to turn off the alarm?
I just received mine and connected it to my linux pc laptop for the first time. It makes constant dial up modem noise non-stop. I’m assuming I have to connect this way to run the commands required to set this thing up?
It worked! No more horrible dial up noise!
I was plugged into ttyACM3: sudo echo -ne ‘a’ > /dev/ttyACM3
I downloaded autoserial.py from https://github.com/BrewPi/brewpi-script and it gave me the answer.
