[Webmobi]

Our code is 21k excluding soft-device,as per the example 15k should be the max size limit of code to update FOTA. Is it possible to make changes in DFU bootloader so that i can transfer FOTA?

Hi DMS,

What do you mean by " per the example 15k should be the max size limit of code to update FOTA". With 512kB flash chip, the max sixe of the application should be 356kB as shown here.
