Duplicate SSID not handled. about wifinina HOT 9 OPEN

@thorium-g would you be able to share the sketch you are using?

from wifinina.

@sandeepmistry Sure, and thanks for your reply. This sketch is based on "the nerd example" packed with wifinina 1.4.0.

I further investigated and refreshed my knowledge about Layer 1&2 WiFi. LLC (Physical Addressing) (Hardware Address + BSSID) is typically used to uniquely identify wifi-networks.

I´m a native perl not c coder and with the "missing" documentation in wifi_drv.cpp spi_drv.cpp I am not able to provide a fix by myself, sry.

@sandeepmistry If you are looking for a free and usable wifi-scanner I can recommend WifiInfoView by nirsoft.net. Other tools I used are inssider (needs registration now :/) and Netstumbler (supports only limited set of wifi chipsets).

Also I am looking for option to gather info and details from the network I am actually connected to. It looks like, from what I can tell from the sourcecode of wifinina, that some of the function are implemented in wifi_drv.cpp but not (yet) integrated into the wifinina interface.

@facchinm any thoughts on this? Really I think we are stuck with what the esp-idf provides in terms of scanning ...

@thorium-g are the channels of the networks you are scanning the same? See the ScanNetworksAdvanced.ino example sketch, for example how to get the channel.

Hi @thorium-g, are you still interested in this? Please see my comment above ...

Hi! We are running into a similar problem.
We DO have networks with similar SSID's and would like to be able to connect to a specific one (the one that has the best signal)
Being able to specify an ID in begin() rather than the SSID would be great, looking at the code I wouldn't know how to proceed. any help would be greatly appreciated thanks

Hello, I am also stucking into this problem.
Any way to choose which SSID to connect to in case of many network with the same SSID? As previously suggested, BSSID seems to be ok, otherwise SSID + channel.

Thank you

Hello!
We have the same issue and we have purchased 10 devices already, but this issue is critical.
Is there any solution currently?

Help would be greatly appreciated thanks

Found solution.
Get WiFi module source code from here: https://github.com/arduino/nina-fw
in WiFi.ccp modify WiFiClass::begin(const char* ssid, const char* key) method:
Change wifiConfig.sta.scan_method = WIFI_FAST_SCAN; to wifiConfig.sta.scan_method = WIFI_ALL_CHANNEL_SCAN;
Add new code line wifiConfig.sta.sort_method=WIFI_CONNECT_AP_BY_SIGNAL

After follow Readme building steps: https://github.com/arduino/nina-fw

For additional ESP32 configuration see: https://docs.espressif.com/projects/esp-idf/en/v4.0.3/api-guides/wifi.html#wi-fi-reconnect
