Hi Antonio, Thanks for your information. The interrupt is working fine now. After all, the problem comes from the fact that the the interrupt is not mapped correctly in the sensor board driver layer, which is tos/sensorboards/mts310/MicM.nc. The work around would be change the INT3 and SIG_INTERRUPT3 in this file into 7 and SIG_INTERRUPT7 correspondingly.
Thanks again for your information!
