WiFi - Power Save

Hi All, I'm trying to enable WiFi power save mode on an SF6 Board. I know the CYW43x is capable of doing so and is also implemented in WICED. Looking in the driver files of micropython in "cyw43_ctrl.c" and "cyw43_ll.h", I'm guessing cyw43_wifi_ pm configures the power mode of the chip. Due the the ...

libcyw43.a Source

Hello Everyone, I'm working with the PYBD boards for a while. I'm at a point where I need to seperate Bluetooth and WiFi firmware from being in one library. I wanted to work on the library file libcyw43.a. There was the intention to release its source here https://github.com/micropython/micropython/...

WiFi Tx Transimission power and Bitrate settings

Hello,

I have one microptyhon board (SF6W) working with WiFi. I was wondering if you can change the bitrate to MCS7 for instance and also the Transmission power. Can someone point if it is currently possible ?

Thank you

Re: WIFI Debug Messages

Thank you for the answer. What I mean is that I can I upload the entire DFU image on the Internal flash and also the second external Flash.

I'm dealing with the second external flash mainly. Can you please point what must be changed in order to get the wifi fully initialized ?

WIFI Debug Messages

Hello everyone, I have an issue with starting the WIFI for the PYBD-SF2 board after changing the QSPI Flash for a larger one. It does look like it was obviously caused by the flash. The interesting thing is that I can upload the WIFI firmware on the second external flash with good bitrate using the ...

Re: CYW4343x Firmware update

Sorry for ambiguity. I'm trying to get the stm32h7 working with the 1dx. I'm still dealing to get the 1DX to boot. The 1DX firmware resides in TEXT1_ADDR. Assuming the SDIO is initilazing, I can't seem to get a feedback (Wl_HOST high ?) from 1DX. I see that there is some support for the h7 in the mi...

Re: CYW4343x Firmware update

Thank you for your reply, I'll try to go for the contact for more details. I was wondering where the lib file gets the external Flash address to execute the firmware. Any ideas ?

Thank you

Re: CYW4343x Firmware update

Thank you for your answer. I suppose the code points to " fw_4343WA1_7_45_98_50_start " to indicate where the cyw43 firmware starts which is called by cywbt_activate () and other function from the library. Now the latter is not called anywhere obvious except maybe in cyw43_ll_init(). Can you clarify...
