Hi,

I am looking for a way to timestamp packets as soon as they arrive over BLE. Any directions?

Can someone explain what this line of code does:
It is a part of the timer_get_counter_value() function here: https://github.com/espressif/esp-idf/bl ... er/timer.c

I want to use 80 MHz clock for my timer. But esp32 only allows us to use timer_divider values between 2 and 65536? How can I set it to 1?

Is it possible to generate an interrupt when a packet is received over BLE or Wifi?

I am looking to generate an interrupt and time stamp the packet.

Hi, I am trying to write a program to: 1) start a timer 2) read its value at any time 3) multiply it by 12.5 to get time in nanoseconds. I have modified the timer_group code. here's my app_main. I am trying to start my timer, read it fifty times and then print the results. I want to see how long doe...

I am trying to create a timer to get value in nano seconds. For this, I am using the "timer_group" example where I set the "TIMER_DIVIDER" to 1 in order to get 12.5 ns per tick. However, I get the following error: timer_group: timer_init(214): HW TIMER divider outside of [2, 65536] range error Does ...

That implementation is going to be, basically: start the timer with a prescaler of 1, and when you need to know the value of time in nanoseconds, read the counter and multiply by 12.5ns.

Thanks, any do you have a sample on Github for this?

Hi,

I am looking to get time with nanoseconds precision. I know the function esp_timer_get_time() gives time in microseconds. I was hoping that I can modify it. Where can I find the source code/documentation to how it works.?

Thanks

Hi, I am looking for a way to get the time since boot with nanoseconds precision. Currently, the best I can do is esp_timer_get_time() which returns time with microsecond precision. I connected my board to an oscilloscope and found out that it takes around 1.29 us for the esp_timer_get_time() functi...
