network_interface_wifi_station_espressif_start hang-up about simba

[eerimoq]

I made some changes to the network interface connection handling to give a solution to this. The start function no longer blocks until a connection has been established. The application can use the new ´´function network_interface_wifi_station_espressif_ip_up()´´ to check the interface status.

See this commit for the implementaiton: b442715

Note that that commit is not yet tested. I'll test it after work.

Let me know if you have other suggestions about how to improve the API.

Thanks.

i am using esp12e board, platformio 3.0.1
main.c code like this, dhcp get ip address 192.168.201.117
but this code can not open http 8000 port
is there something i forgot to do ?
thank you :)

The ip address of the TCP socket listening for connection is hard coded in the http server. I will fix that bug tonight.

Meanwhile, replace

https://github.com/eerimoq/simba/blob/master/src/inet/http_server.c#L325

with

inet_aton(listener_p->address_p, &addr.ip);

so the ip address will be correct.

esp12e also support softap mode
is there some plan to add module support it ?

[eerimoq]

No not for now. I'm all busy porting MicroPython to Simba (Pumbaa). Python on microcontrollers is quite nice =)

A fix for the HTTP server problem has been implemented and will be included in future releases.
