@fossette said in How many stations connecting to Omega2's Access Point at the same time?:

DOUBLE POST! The conversation should resume here:
https://community.onion.io/topic/1061/access-point-questions

I have read this conversation before posting. At that time, I didn't catach the information.
Now, I read carefully again, it is clarified that "omeag 2 (openWRT) AP's client limitation is 253."
Thank you for your reminding.

@WereCatf said in Please clarify the SPI maximum clock frequency.:

@igotit-anything 25MHz.

Yes! good enough. thank you for quik reply.

Hi,

Now, I'm designing that my system's MCU (STM32) communicate with omega2 via SPI.
The SPI clock should be over 20MHz.

omega2's SPI and SPI C Library can be available over 20MHz SPI clock?

What is the maximum clock frequency of the omega2's SPI.

Hi,

When Omega2 is in AP mode,

What is the maximum number of stations which can be connected to the Omega2 Access Point at the same time ?

In general, other wifi module's softAP limits the station number. For example, espressif's esp32 AP can be connected only four staions at the same time.

Omeag2 AP has a limitation of connectable stations ?

@fossette said in spi to wifi possible?:

@igotit-anything Use the SPI functions to read, and use the Ethernet socket functions to send. You have lots of details to clarify, for example the use of a TCP or UDP port. Plus, at that rate, WiFi may become a bottleneck... Perhaps you should consider the use of an Ethernet cable instead.

Thankyou fossette,

Unlike uart to wifi, it may be needed that low level C coding shoud be taken.

My application should be wireless TCP socket between two omega2 modules. The one is a station with tcp server and the other is an access point with tcp socket client.The distance between two modules is under 10meters.
I can not find the information about real maximum throughput using omega2.
Just I guess that the 10Mbps throughput can be achieved via omega2's 802.11n wifi.

My external mcu(STM32) needs to send data( the data rate is over 10Mbps) to omega2 via spi and then finally the data feed into WiFi TCP.

In the case of UART , the "serial to wifi" can be achieved by using the ser2net (https://www.youtube.com/watch?v=_OVRr69Apl0) or socat library.

However, I don't have any idea how can I make the "SPI to WiFi".

Is there any method to achieve "SPI to WiFi" ?
Or if not available, please recommend the "I2S to WiFi" solutions.

Thanks in advance.
