I2C has acknowledge failure while working as slave transmitter

[MSamy.1]

Hi,

I’m using stm32f103 as slave transmitter with arduino uno as master

As far as I understand the stm sends the data bytes correctly then waits for ack for the last data byte but arduino sends stop instead of ack, stop

stm ack failure flag is raised and enters err interrupt

So how to disable the waiting for the last data byte ack ?

Or how to force arduino to send the last ack ?
