One of my colleague has an issue with CPAL that ppl might have seen before (when being used for I2C communication on the SMT32L15R6...

It appears to do start communicating, sends the start, sends the address and then gets an ack back. the SCLK line is then help low for a significant amount of time (~25ms) and then the communications carries on without any issue.

The communication appears to happen OK, but obviously this delay is unfortunate...

During CPAL i2c communication, the SCL line stay low for a significant time (20-30 ms).

My solution was in cpal option CPAL_DEBUG. This mode was cause of long delays in transfer. Hope it will be helpful for someone.
