- Sun Nov 09, 2014 12:43 pm #2373 Can you add powersave functions like deepsleep or sleep

Maybe it help.

Code: Select all wifi_set_ip_info, please call it in user_init.

Example:

    {
struct ip_info info;

IP4_ADDR(&info.ip, 10, 10, 10, 1);
IP4_ADDR(&info.gw, 10, 10, 10, 1);
IP4_ADDR(&info.netmask, 255, 255, 255, 0);
wifi_set_ip_info(SOFTAP_IF, &info);
}

Yep, they expect it to be called in user_init() and any subsequent calls will NOT work for STA mode.
For AP, if you set wireless mode to none in user_init() you can configure IP once and then set mode to AP.
However the command line interface is fired aftter user_init, so we have to either store IP somewhere in flash and apply on boot. Still looking for proper spi flash layout map.

Can you add powersave functions like deepsleep or sleep

Done, check the git repo. Binaries are updated as well. I've added gpio command, so you can read/write GPIO from commandline. So far only GPIO0 and GPIO2 are MUXed as GPIO on startup. We need a proper GPIOMUX command.
ifconfig now only displays info on active interfaces and displays iface state as well.
Regarding deep sleep - my modules don't seem to exit correctly out of deep sleep. I can see they get reset after the timeout, but instead of booting I get garbage that looks like as if my module has entered bootloader mode.
I found no references to 'normal' sleep in the doc, so I suggest you can just bring down the wireless interface with 'iwmode NONE' and that should be sufficient. It will disconnect from your base station.

The summary of current commands is below:

Code: Select allhelp       - Show this message
apconfig   - Setup Access Point.
             apconfig name OPEN/WEP/WPA_PSK/WPA2_PSK/WPA_WPA2_PSK [password]
iwconnect  - Join a network/Display connection status.
             iwconnect ssid password
iwmode     - Get/set wireless mode. Available modes: NONE, STA, AP, APSTA
             iwmode STA
iwscan     - Scan for available stations
ifconfig   - Show/setup network interfaces
             ifconfig [iface] [ipaddr] [netmask] [gateway]
             ifconfig sta0 192.168.0.1 255.255.255.0 192.168.0.8
argtest    - Print out argc/argv
deepsleep  - Enter deep sleep for some microseconds
             deepsleep 10000
reset      - Soft-reboot the device
meminfo    - Display memory information
version    - Display version information and copyright
gpio       - Control gpio lines. gpio mode line [value]
             gpio in 0
             gpio out 0 1

- Sun Nov 09, 2014 4:17 pm #2382 deep sleep mode a little different from other mcu's. if we want to sleep and auto wake up after some microsecond, we must connect gpio16 with rst pin. but i have just esp-01 module and i cant try this.
gpio0 control bootloader status when power up module. so maybe we cant use for gpio out before disabling this mode.
one more thing. can we set auto send data to the website with tcp connection and maybe can set time interval for this.
