Hex size is not reducing size while converting to zip

[Sawan Kumar]

I tried to reduced my hex file's size while converting to zip but it doesn't get size under 256KB due to which I am getting an error: Data size exceeds the limit.

Below are the screenshots for reference.

I need help to resolve this problem,

It doesn't work that way. You need to reduce your code size, not attempt to compress the hex file.

Try compiling with size optimizations, disable logging, etc.

I don't have any project whose size is small all are bigger than 400 KB. What i should do?

When I create hex file from makecode and flash it using usb is woking but when try to do it over Bluetooth it's not working

Binary is still same size of hex and is not reducing

Because Samsung microbit hex2bin converter is reducing size but its not woriking in ios lib of IOS-Pods-DFU-Library.

It doesn't reduce the size, it's just a different representation. A hex file is just a text file. A binary file is just 1's and 0's. Therefore the binary file it's smaller.

The hex file in the end is used to create a binary file. I believe that the DFU zip files have a binary inside, not a hex file.
