Really, really annoying things with Apple products, every day:
– My iPhone 6S has battery malfunction (shuts down at 40% of battery level and refuses to start) and is under warranty change. However the repair shops cannot get the batteries because of high demand. Apple calls this issue affecting small amount of iPhones. I doubt it.
– Using “night mode” which mutes the iPhone automatically during night. However when plugging the charging cable makes “pling” noise when everything else is muted. Really nice because when rest of family is sleeping and you want to charge overnight.
– Forget to put the phone on charging. Wakes me up at morning still, good boy. To shut off the alert I need to enter my 6 digit passcode (because the phone rebooted). Why I need to enter passcode on reboot? Isn’t the fingerprint scanning enough secure?! Trying to tap the passcode without eyeglasses immediately when woken up is like a nasty test.
– Apple releases new Macbook (finally) and I was waiting to replace my old Macbook with brand new. Apple raises prices and removes USB ports and SD card slot on new model. Well played, Apple.
– I purchase previous model Macbook because of previous issue and think 128GB is enough for the “internal” SSD. I was wrong, installed Xcode and constantly running out of disk. Irritating me with nags. The internal SSD cannot be replaced. Need to use external hard disks.
– My iPad wants to make OS upgrade but I don’t want to do it. Asks it every day. With two dialogs. I. DON’T. WANT. TO. UPDATE. PLEASE. LET. ME. CONTINUE. Solution: there isn’t any real solution, but you can hack it.
- Use software serials ONLY for debugging. Software serials are not reliable.
– Use hardware serials primarily for interfacing with devices (GPS etc.)
– Prepare for debugging port in your design
– Program the uC through native programming method (ISP, ICSP) if you don’t have several hardware USARTs
– Make all sorts of cross-compatible adapters and cables for easy debugging
– Use two laptops for development: one for plainly debugging
When picking uC, make sure you have plenty of hardware serials. Usually one isn’t enough.

(empty field) time in seconds since last DGPS update
(empty field) DGPS station ID number
*47 the checksum data, always begins with *
If the height of geoid is missing then the altitude should be suspect. Some non-standard implementations report altitude with respect to the ellipsoid rather than geoid altitude. Some units do not report negative altitudes at all. This is the only sentence that reports altitude.
