Hi Ruben, Have you been able to monitor the LC sensor oscillation variations across temperature? I believe that the current spikes you are observing are due to the fact that the MSP is waking up due to incorrect transition detection. Once you obtain oscillations variations there are somethings you might want to try: Analyze the the LC sensor oscillation variation and determine the type of frequency and amplitude oscillation changes you have across temperature. Based on the analysis of the LC sensor oscillation variations determine if the analog hysteresis in the ESI module need to be adjusted to minimize the effect of temperature on the coils. If adjusting the hysteresis of the ESI module does not solve the problem an alternative could be to develop a calibration routine using the msp internal temperature sensor and recalibrate the TSM registers and ESIDAC registers taking into account the ambient temperature.
