Prepare for checkout doesn't reset idle timer #75
Description
When running without external power, the Reader will go to sleep after approximately 4 minutes. I am attempting to prevent the reader going to sleep as I need to be ready to take a payment quickly.
The SumUpSDK.prepareForCheckout() method is very useful to wake the reader once it's gone to sleep. However, the device can still go to sleep immediately after a call to this method if it's 4 minute idle timer is reached.
Ideally a call to prepare would tell the device that a checkout is imminent, resetting it's idle timer and thus preventing it going to sleep for a further 4 mins.
If there are any other suggestions for preventing the reader from sleeping I'd be glad to hear them!
Many thanks,
Meurig
