[satyam9896]

SO I HAVE STARTED MY PROJECT WITH STM32L072 SERIES WHICH IS HAVING 192B FLASH 64 PIN IC along with bluenrg-m2sa. my concern and doubt is regarding implementation of ota feature to stm32l072 ic which i never implemented and work on before and also the examples and other refrences are mostly availabe for L4 or F series IC so my request to give me and help me with appropriate resoures and file so that i can easily implement the ota feature to my project and can easily understand also.
