I am using the BLE 1.4.2 stack on the CC2541 device (actually a JDY-08 module). When enabling the i2c slave driver using interrupts the bluetooth connection suddenly drops in the first few minutes. The I2C slave is only accessed for writing 3 bytes every 1 minute for 16 events every 1 second. Looking at the I2C protocol the data is not clock stretched. There is no other I2C traffic on the bus. There is a similar question here in the forum, but the thread is locked and I cannot see any resolution to the problem e2e.ti.com/.../571254
Anybody out there using the i2c slave mode successfully?
Thanks
Kai
