a)
I tested a little program to Scan the Network.
void setup()
{
WiFiSpi.init();
...
status = WiFiSpi.begin(ssid, pass);
...
}
void loop()
{
int numSsid = WiFiSpi.scanNetworks();
...
}
As you can see below if, the name of SSID is more long then the previous,
in the next scan we have the short name filled with the exceeding chars,
in this case "GB".
Opening port

b)
In my applications, all use UDP, I have the following sequence:
1- WiFi.mode(WIFI_STA);
2- WiFi.disconnect();
3- ApSsidFound = WiFi.scanNetworks();
select the AP with best signal
4- ApSsidS = WiFi.SSID(ApSsidSelect);
then connect the AP
5- WiFi.config(ApIp, ApGateway, ApSubnet, ApDns);
6- WiFi.begin(ApSsid, ApPassword);
at the end connect UDP
7- UDP.begin(UdpLocalPort)
I was not able to find how to build the same sequence with WiFiSpi.
Thanks.
