ABTemp Beacon firmware update to 1.1 gives wrong temperature


#1

Hi,

I recently updated my ABTemp beacon to firmware 1.1 using the instructions here: ABTemp sensor measure range

After upgrading, I’m getting a minor value of [220, 59] which means it has a temperature of -572.3125.

That’s obviously not right.

Also, that value never changes (when put in heat, it doesn’t go up).

I think the firmware is incorrect.

Please tell me the correct firmware to use or give me the original firmware to downgrade to.

Thanks,

hello,

We re-built the firmware and it works again. Please download the firmware v1.1.0 here

How To Calculate Temperature

    // Convert the data to 12-bits
    double cTemp = 0.0, fTemp = 0.0;
    int temp = ((minor[0] * 256) + (minor[1])) / 16;
    if(temp > 2048)
    {
        temp -= 4096;
    }

    cTemp = temp * 0.0625;
    fTemp = cTemp * 1.8 + 32;

Great! That works perfectly!

Thank you very much!
