FXTH871xD stop modes and wake up

mouaiadsalaas · ‎06-21-2021

Hi.

I am new with FXTH871xD and I want to know if it is possible to make him sleep and wake up when there is change in pressure or acceleration.

if that possible can you tell me where to start and if there are any examples or documents about sleep and wake up it would be useful.

Thank you very much.

Hi Mouaiad,

Unfortunately, the FXTH and NTM88 are not able to wake up on pressure or acceleration change.

The wakeup on sensor change is something we will integrate to our next TPMS generation, but again, it is not available with the existing families.

With the FXTH and NTM88, the application must be programmed to wake up periodically on PWU timer and take sensor measurements upon wakeup.

The Starter Package for FXTH87/87E that can be downloaded from here includes demo projects named “FXTH87_E_xx_Periodic_RF_Tx" which use the PWU block to wakeup the device periodically and trigger sensor measurements.

Best regards,

Tomas
