We want to update the firmware over the air (BLE).
What is a safty concept?
Our firmware need about 60KB flash ROM.
What have we to calculate for BLE software?
My idea is a flash 256KB (2x128KB).
2 banks 128KB. One bank for safty.
Do you have software for this function?
If you will use dual bank DFU then you will have this:
80KB for S110 v6 + 16KB for bootloader + 2*80KB for application
So maximum available flash size for your application is 80KB.
