[ESP32] wifi setup provisionning, web SoftAP using 1.5.1 and 3.3.1 IDF

gilles · September 17, 2020, 11:20am

Hi support teams,

I need a confirmation that

is still working using new 1.5.1 BSP (upgrade to 3.3.1 IDF) ?

Simple wifi connection (AP and join) works fine, so WIFI ESP driver is OK

But when starting with headless provisionning softAP web example , Wifi seems not up , can’t see SSID…)

I (1489) wifi: mode : sta (bc:dd:c2:d1:b9:5c)
D (1499) event: SYSTEM_EVENT_STA_START
[ESP32 Wifi Driver][INFO] Station/SoftAP started
[ESP32 Wifi Driver][INFO] Wifi module started
[ESP32 Wifi Driver][DEBUG] (WIFI_ESP32_netif_is_started_f)
null INFO: Server started on unknown:80

Can you confirm ?

thanks

Hi Gilles,

I just ran the example (com.microej.example.wifi.setup.web) using the ESP32-WROVER platform 1.5.1 and it works.

From your logs, it seems the WiFi driver is in station mode instead of the soft AP mode.

I suppose there are no errors nor other wifi mode changes logged prior to the logs you provided: correct ?

What is the Java entrypoint you are using ?
I would expect to see at least the following line :
[ESP32 Wifi Driver][DEBUG] (WIFI_ESP32_enable_softap_f) ssid = MicroEJ_SoftAP

Ok, so you are also using the com.microej.example.wifi.setup.web but with custom __NET_MASK, __USE_DHCP and __SOFT_AP_SECURITY values : right ?
Can you provide us the values you are using ?

The scan should be done before null INFO: Server started on unknown:80 is logged. Here is the call hierarchy :

scan(boolean) : AccessPoint[] - ej.ecom.wifi.WifiManager
scanAccessPoints() : AccessPoint[] - ej.net.util.wifi.WifiNetworkManager
scan() : AccessPoint[] - com.microej.example.wifi.setup.SoftAPConnector
updateAccesses() : void - com.microej.example.wifi.setup.rest.RestSoftAPConnector
start() : void - com.microej.example.wifi.setup.rest.RestSoftAPConnector
start(RestSoftAPConnector, String, String, boolean, String, String, SecurityMode) : void - com.microej.example.wifi.setup.rest.Main
main(String[]) : void - com.microej.example.wifi.setup.web.Main

The scan should be the first non-configuration operation. Did you override something in this hierarchy ? (WebSoftAPConnector.start() for example)

Otherwise, you can check whether the native is actually called or not by enabling the LLECOM_WIFI traces in the file ecom-wifi/src/LLECOM_WIFI.c (l.20).

It seems to me the application execution flow is broken but no exception is logged

Did you try to execute the example with your modifications on the simulator ?

Hope it helps,
Rémy

HI Rémy,

Your Guess is right : Since I had to redefine ‘OnSuccessJoin’ method to put custom in it :
I also typo a copy paste ‘@Override’ on Start method , reason why scan dit not start
No issue , this thread should be deleted , sorry for that
