This library allows you to have the OTA features on SAMD21 based boards (like MKR1000, Zero and MKRZero) using the WiFi 101 shield or the builtin WiFi capabilities of the MKR1000. The sketch to be loaded Over The Air can be stored on two media:
In the first case the new sketch can't exceed the half of the total memory (256/2 = 128kB) while in the second case you have all the MCU's flash available.
Corrections, suggestions, and new documentation should be posted to the Forum.
