Maximum bytes per message

[xpeedster]

Hi, in my actual project I need to send a payload of 12 bytes using i2c. I have tried it, but only 4 bytes are sent in a single I2C message. Is there a maximum payload size of 4 bytes? If this is it, can this be changed?

Thank you for the help.

Single I2C message, maximum payload is controlled by I2CDevice.page_bytes, read your I2C device datasheet to get this parameter, or just adjust page_bytes to 16 or larger.
