问题 I am working with Android and ISO14443 type B tags and there is an issue that I am not able to solve. Hopefully someone can give a hint. When NFC setting of the phone are turned on, it starts sending REQA and REQB commands in order to discover if any tag is present. The issue is that by default this is done with a periodicity of 2 seconds and I would like to modify that time to make it shorter. I see that most apps maintain this scan period, but there are some apps such as TagInfo from NXP

问题 I'm developing a "background task enabled" app that connects to a BLE (bluetooth low energy) device. The user opens the app and connects to the BLE while the app is in the foreground. Once the app goes to the background it will keep communication open with the device (if in range) and be alert of any information received from such device. Now my question is how do I handle or even notice that data is coming from the device? It seems that right now my notifications are queued and are only

问题 LibreOffice Calc spreadsheet offers a function ISOWEEKNUM to return the standard ISO 8601 week number of the specified date. I want the opposite. ➠ Given a standard week number, give me the date of the first day of that week (the Monday date). Passing integers is acceptable. Also nice if able to pass a string in standard format. Like this: DATE_OF_ISOWEEKNUM( 2017 , 42 ) ➝ date of Monday of week 42 in week-based year 2017 DATE_OF_ISOWEEKNUM( "2017-W42" ) ➝ date of Monday of week 42 in week

问题 According to the standard, what is the difference in behavior between declaring variables in control structures versus declaring variables elsewhere? I can't seem to find any mention of it. If what I'm referring to isn't clear, here's an example: if (std::shared_ptr<Object> obj = objWeakPtr.lock()) As you can see, I'm declaring and initializing a local variable, obj , in the if block. Also, is there any technical reason as to why this syntax isn't given any special behavior when used in place
