How to make application for a 128kb QFAB chip

[Flagada15]

Hi again!

Thank you for all your answers this community is great! :-)

I am trying to develop a small app to be flashed on QFAB chips but I am facing a memory size problem.

If I am not wrong those QFAB chips have 128kb of flash memory available. The S130 SoftDevice already uses 112kb of this memory so only 16kb memory is left for the application.

I am developping on mbed and if I make a simple led blink program the code takes approximately 12kb so it works. But if I try to make a simple ble program with just an advertising tag it takes more than 30kb so it cannot be entirely flashed on the chip.

So my question is how can we developp ble application on the QFAB chips? Is there a way to make smaller application (without mbed maybe) or is it mandatory not to use softdevice or a smaller one?

Thanks!

Thank your for your answer, I will take a look at keil and gcc. I was looking at this beacause I already have QFAB at disposal. I didn't though that the smallest BLE application couldn't be flashed on those chips. The other question is if it is not possible to make a simple BLE app for those chips what can we do with them and why are they sold?
