Hi

Does ST have any WIFI chip with FTM?

Thanks

No, ST does not offer Wi‑Fi FTM. But if you outline your use case, an alternative solution within the ST portfolio might be possible.

Hi

what I need to do is to synchronise 2 devices over WIFI.

I need a 32 bit timer on stm32 which runs with less than 50 microsencond accuracy in comparison to a second device which also has a STM32.

One device may be configured as client and the other device as router or server.
Does the ST framework give me access to : (TSF) Timing Synchronization Function of 802.11?

See here:

You mean less than 50 us error ?

 

But, as @Peter BENSCH said, you still haven't said why you (think you) need this ?

ie, what is your end goal here? What are you trying to achieve ?

 

Describe the goal, not the step.

Hi  @Peter BENSCH 

any news here?

Do you know: Does the ST framework give me access to : (TSF) Timing Synchronization Function of 802.11?

Thx

Hi @Andrew Neil 

thanks. 

On my STM32 device I want to make a ADC measurement. 

I don't have one device but 10 (or lets say n) devies. All these 10 (or n) embedded Devices are connected via WIFI. 

I want all these 10 devices to initiate the ADC conversion at the same time (+/- 50 us accuracy). 

For this purpose I want synchronise all devices with an accuracy of ~50 us. 

Did I manage to describe it properly? ;)

@Andrew Neil ideally i would stay withhin the STM32 world (ESP32 is not from ST?). Is this possible with ST's offerings as well? 

Second Question: Does the ST framework give me access to : (TSF) Timing Synchronization Function of 802.11?

Thx

Correct.

Currently, ST's only WiFi product is the ST67W611M1  module.

It supports IEEE 802.11b/g/n/ax:

By anay chance : do you know if ST67W611M1 provides access to (TSF) Timing Synchronization Function?

Again, that's a separate question.

But I don't know.
