What is the maximum data length we can use for one I2C transaction?
We are using CYW20721B2 module.
Information for function uint8_t wiced_hal_i2c_write(uint8_t* data, uint16_t length, uint8_t slave); mentions this:
/// ....Though any arbitrary length of data may be
/// written to the slave, atomic transactions greater than HW's capability
/// are not possible - they will be split into multiple transactions....

Hello,
For 20xx devices, i2c payload is limited by 64bytes.
Please have a look at similar threads :
