In a design where the ECO trim was not correctly set in the fixed stack per ECO Capacitance Trim Values for EZ-BLE™ Modules - KBA218990 , does setting the trim in the application code fix the problem? Or does the trim value get reset when starting the fixed stack bootloader code?
The ECO trim value will get reset when the bootloader starts. So, you have to set it from both bootloader and bootloadable projects.
Thanks and Regards,
