WiFi AP

[nadvorvo]

Hi everyone,
I am following this tutorial:
https://docs.pycom.io/tutorials/networks/wlan/#connecting-to-the-device
But I can not see created AP from NTB.

When Connecting to a Router everything alright (ftp, ssh, ping).
https://docs.pycom.io/tutorials/networks/wlan/#connecting-to-a-router

Thank you in advance for your assistance.
Regards, Vojtech

Test script:

from network import WLAN
wlan = WLAN(mode=WLAN.AP, ssid='hello world')
wlan.init()
print(wlan.ifconfig(id=1)) #id =1 signifies the AP interface
while True:
    print("isconnected:",wlan.isconnected(), wlan.ifconfig(id=1))

output:

('192.168.4.1', '255.255.255.0', '192.168.4.1', '0.0.0.0')
isconnected: False ('192.168.4.1', '255.255.255.0', '192.168.4.1', '0.0.0.0')
isconnected: False ('192.168.4.1', '255.255.255.0', '192.168.4.1', '0.0.0.0')

I am getting wlan.antenna() = 2 ?

>>> wlan.antenna()
2
>>> WLAN.EXT_ANT
1
>>> WLAN.INT_ANT
0

system version:
(sysname='GPy', nodename='GPy', release='1.20.2.r4', version='v1.11-ffb0e1c on 2021-01-12', machine='GPy with ESP32', pybytes='1.6.1')

@nadvorvo You could try to deactivate pybytes, for instance with:

import pycom
pycom.pybytes_on_boot(False)

Hi @robert-hh,
Thank you for your reply.

I have deactivated pybytes, but I can not see created AP from NTB.

pycom.pybytes_on_boot()
False

Then I tried to activate wifi_on_boot

import pycom
from network import WLAN
pycom.pybytes_on_boot(False) #we do not want Pybytes using the WLAN
pycom.smart_config_on_boot(False) #we also do not want smart config
pycom.wifi_on_boot(True)
pycom.wifi_mode_on_boot(WLAN.AP)
pycom.wifi_ssid_ap('ssid')

I can see wifi AP now.

Then I tried to deactivate wifi_on_boot

pycom.wifi_on_boot(False)

no wifi AP now.

remove this lines as they are not relevant to AP mode - and this code never ending

This is WLAN.MAN_ANT, as you're not explicitly setting the antenna. MAN_ANT refers to manual antenna, and defaults to the internal antenna selected. In this mode, you can manually change P12 to reflect the antenna setting, and is used for the OEM modules, as they do not have an antenna switch.

I looked at this for a long time, but then figured it out. There is a slight mistake in the example. If you remove the line wlan.init(), or transfer the arguments from wlan = WLAN() to wlan.init() it will work. What is happening is that wlan.init() overrides the settings in wlan = WLAN().
I will change the example
Sorry for the inconvenience,
Gijs

@Gijs this is a common trap. The init() calls of a device have to carry all parameters that are different from the default, since it usually sets all parameters.

Hi @Gijs
I really appreciate the support you’ve given me. I have testes, everything all right.
