Hello,

It looks to me like that driver took care of this error itself by performing a garbage collection when the buffer was filled, did you experience any issue when this happened?
If you want to increase your Peer manager flash storage you can do so by changing this configuration in sdk_config.h:

// <o> PM_FLASH_BUFFERS - Number of internal buffers for flash operations. 
// <i> Decrease this value to lower RAM usage.

#ifndef PM_FLASH_BUFFERS
#define PM_FLASH_BUFFERS 4
#endif

Best regards,
Karl
