https://devzone.nordicsemi.com/f/nordic-q-a/47302/timer-synchronization-between-nrf52832-with-stm32I want two STM32 timers synchronization via BLE . Used two nRF52832DKs download the timersync demo : https://github.com/nordic-auko/nRF5-ble-timesync-demo , the nRF52832DKs timers are synchronous. But how to Synchronize STM32 and NRF timers.en-USTelligent Community 13Wed, 15 May 2019 09:59:35 GMThttps://devzone.nordicsemi.com/thread/187188?ContentTypeID=1Wed, 15 May 2019 09:59:35 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f1bffd72-72bb-4c82-8d8f-1f0b1d919c67Hung Bui<p>Hi Skyliu,&nbsp;</p> <p>Since the nRF52 and the STM32 can be connected via a wire. You can use that to synchronize the timer. For example when the GPIO pin is toggled the Timer should be reset to 0. It&#39;s deterministic number of cycle of latency from the time you trigger the toggle, until the interrupt is received on the other side (STM32).&nbsp;</p><div style="clear:both;"></div>
