I would like to be able to equip a preconfigured Photon with the access data of my friends WLAN.
For this I have created with set.credentials in total 3 accounts.
If I visit my friend, the photon flashes quickly green, but does not go online.
An output at the serial interfaces for control requires an online connection.
Do I have a thought-failure?
void setup() {
Serial.begin(9600);
// Connects to a network with a specified authentication procedure.
// Options are WPA2, WPA, or WEP.
WiFi.setCredentials("FRITZ!Box 7362 SL", "123", WPA2); // Friend 1
WiFi.setCredentials("Dagobert", "456", WPA2); // Friend 2
WiFi.setCredentials("Ingo Heim", "789", WPA2); // Friend 3
WiFi.connect();
while(Serial.read() < 0 && millis() < 10000) Particle.process(); // this waits here till you connect via Serial and hit a key (or max 10sec)
if (!waitFor(WiFi.ready, 10000))
Serial.println("Not able to connect to WiFi for 10sec");
else
{
Serial.print("Here we go SSID: ");
Serial.println(WiFi.SSID());
}
}
@Postler, you may want to use waitFor(WiFi.connected, 30000); after the WiFi.connect() to give the Photon up to 30secs to connect, which is a typical time to wait.
a.) no success with
WiFi.connect();
waitFor(WiFi.connecting, 30000);
b.) With SYSTEM_THREAD(ENABLED) on top the temp-measurement begins and my Display works,
but the WIFI-Connection is not stable - further breathing fast green.
c.) IMO WiFi is always on as Photon standard.
d.) Cipher params are unknown - my friends using a Fritz!Box - untested at the moment.
e.) If I place WiFi.setCredentials outside setup() I got this error: âWiFiâ does not name a type
Any working example available?
My friend has problems with moisture in his apartment. I like to lend him my photon with a config gladly for a time, so that a time series of measurements can be recorded.
Have you considered using SoftAP to set WiFi creds on demand?
No, not in non-AUTOMATIC system modes and in AUTOMATIC your code won't run before the device has successfully connected to the cloud (unless you use threading).
When using WPA2 you can use AES+TKIP cipher
That is normal. These functions have to be called from within a function.
This is not very comfortable but corresponds to my backup strategy, Moors7.
If I leave the setting-up process to an unfettered third party, a lot can go wrong.
My friends would benefit from it when I prepare it with theres credentials, turn on and go.
In fact, I do not understand why it does not work with set.creds.
The installation process is certainly not left to the user, especially in the case of larger installations.
I will check softAP.
I wonder if the spaces in the SSID names cause problems. I would put underscores instead of spaces. Also, you are looking for the wrong status in the waitFor(). What you have will almost immediately pass the waitFor since it is âconnectingâ. You want to wait for an actual connection with WiFi.connected:
if (!WiFi.connected, 30000) {
Serial.println("Failed to connected to WiFi");
// other actions
}
SYSTEM_THREAD(ENABLED)
void setup() {
Serial.begin(9600);
WiFi.setCredentials("Dagobert", "345", WPA2, WLAN_CIPHER_AES_TKIP);
WiFi.setCredentials("Ingo Heim", "678", WPA2, WLAN_CIPHER_AES_TKIP);
WiFi.connect();
if (!waitFor(WiFi.connecting, 30000)) {
Serial.println("Failed to connected to WiFi");
} else
{
Serial.println("Here we are connected");
}
if (!waitFor(WiFi.ready, 10000)) {
Serial.println("Not able to connect to WiFi for 10sec");
} else
{
Serial.print("Here we go SSID: ");
Serial.println(WiFi.SSID());
}
a.) I delete the first credential setting with "SSID with blank".
b.) I changed the WiFi.connection
photon blinks fast green. same as before.
I´m wondering that the time function update the clock during blinking green.
I thought an cloud-connect is needed therefore.
@Postler, I referred to Particle.connected() which is show as WiFi.connected()! My bad.
I would use WiFi.ready() only with waitFor() since when true, the WiFi is connected AND the Photon has an IP. Set the waifFor() time for 30 seconds and that should do it.
Setting the credentials each time is not necessary since they are stored until cleared.
That will not "clear" the credentials. Instead clear all the credentials by holding the SETUP button down for more than 10 seconds. Then run your code with the setCredentials() only if there are no credentials set:
Again, I need to point out that having spaces in the SSID may be a problem.
The timers are actually based on the interrupt driven millis() timer so ANY connectivity is not required. Try:
SYSTEM_THREAD(ENABLED);
SYSTEM_MODE(SEMI_AUTOMATIC); // Needed otherwise your code is working against the system firmware!
void setup() {
Serial.begin(9600);
if (!WiFi.hasCredentials()) {
WiFi.setCredentials("Dagobert", "345", WPA2, WLAN_CIPHER_AES_TKIP);
WiFi.setCredentials("Ingo Heim", "678", WPA2, WLAN_CIPHER_AES_TKIP);
}
WiFi.connect();
if (!waitFor(WiFi.ready, 30000)) {
Serial.println("Failed to connected to WiFi and get IP");
while(1) Particle.process; // freeze here but allow system firmware to run for OTA
} else
{
Serial.print("Here we go SSID: ");
Serial.println(WiFi.SSID());
}
}
My P is now in status âCloud not connectedâ after i flashed with this creds: first my own âIngo_Heimâ and second line with âDagobertâ (my friend creds).
I then put it into the safe mode (with setup + released reset) and via smartphone app âParticleâ I was able to manually enter my own credits again. After new own access I flashed again without sketch changes and I landed again in âCloud not Connectedâ mode.
It must be because of me that it does not work.
@Postler, if you are looking for internet AND cloud connectivity then I misunderstood. The code only attempts a WiFi connection. If you want both WiFi and cloud connection then you need some minor changes:
SYSTEM_THREAD(ENABLED);
SYSTEM_MODE(SEMI_AUTOMATIC); // Needed otherwise your code is working against the system firmware!
void setup() {
Serial.begin(9600);
if (!WiFi.hasCredentials()) {
WiFi.setCredentials("Dagobert", "345", WPA2, WLAN_CIPHER_AES_TKIP);
WiFi.setCredentials("Ingo Heim", "678", WPA2, WLAN_CIPHER_AES_TKIP);
}
Particle.connect(); // This will connect to WiFi then to the Particle Cloud
if (!waitFor(Particle.connected, 30000)) {
Serial.println("Failed to connected to WiFi and Cloud");
while(1) Particle.process; // freeze here but allow system firmware to run for OTA
} else
{
Serial.print("Here we go SSID: ");
Serial.println(WiFi.SSID());
}
}
Yep, i like both: WiFi and cloud connectivity for my own SSID âIngo Heimâ and in case of comfort for my friend âDagobertâ.
SYSTEM_THREAD(ENABLED)
SYSTEM_MODE(SEMI_AUTOMATIC); // Needed otherwise your code is working against the system firmware!
void setup() {
Serial.begin(9600);
if (!WiFi.hasCredentials()) {
WiFi.setCredentials("Ingo_Heim", "xy", WPA2, WLAN_CIPHER_AES_TKIP);
WiFi.setCredentials("Dagobert", "abc", WPA2, WLAN_CIPHER_AES_TKIP);
}
WiFi.connect(); // This will connect to WiFi then to the Particle Cloud
if (!waitFor(Particle.connected, 30000)) {
Serial.println("Failed to connected to WiFi and Cloud");
while(1) Particle.process; // freeze here but allow system firmware to run for OTA
} else
{
Serial.print("Here we go SSID: ");
Serial.println(WiFi.SSID());
}
/*
if (!waitFor(WiFi.ready, 30000)) {
Serial.println("Failed to connected to WiFi for 30sec and get IP");
while(1) Particle.process; // freeze here but allow system firmware to run for OTA
} else
{
Serial.print("Here we go SSID: ");
Serial.println(WiFi.SSID());
}
*/
After startup for more then 10 sec i got the blue one and transmitted via the Smartphone app my WiFi data.
After I entered the WLAN key, I am manually online and ready to flash.
Flashed âIngo_Heimâ with underscore and P is now breathing slow green (imo cloud not connected mode).
Also get âFailed to connected to WiFi and Cloudâ by serial mon.
Update: I saw a mistake from me: Particle.connect(); - change it immediately and P is connected. Puh.
Next day I´m going to my friend - standby Thank you for your support up to here.
Today I was on a cup of coffee with my friend for the test of the prepared WLAN access: I started the footpath with a breathing normal Photon - my connection became weaker - and the P waved into the green flashing.
Property then in the corridor of the friend âsetupâ longer than 10 sec pressed to blue flickers.
Power off and on and had hoped that then the credentials from the sketch would be used.
Have the message âFailed to connected to WiFi and Cloudâ received. Well, it was worth it.
Whatâs wrong with this code? Iâm running it on a P1 but it doesnât ever seem to run the setup function â I put a !Serial.available loop before the WiFi code but it doesnât seem to ever get there. Iâve tried using system thread as well. Iâm on 0.6.2:
#include "application.h"
String SSID = "ssid";
String PASSWORD = "pw";
uint SECURITY = 3;
uint CIPHER = 1;
SYSTEM_MODE(SEMI_AUTOMATIC)
void setup(void) {
Serial.begin(115200);
Serial1.begin(19200);
WiFiAccessPoint ap[5];
int found = WiFi.getCredentials(ap, 5);
int hasCredentials = 0;
for (int i = 0; i < found; i++) {
if (ap[i].ssid == SSID) {
hasCredentials++;
}
}
if (hasCredentials == 0) {
WiFi.setCredentials(SSID, PASSWORD, SECURITY, CIPHER);
}
WiFi.connect();
if (!waitFor(WiFi.ready, 30000)) {
RGB.color(255, 0, 255);
Serial.println("Failed to connected to WiFi and get IP");
while(1) {
Particle.process();
}
}
RGB.control(true);
RGB.color(255, 255, 255);
Serial.println("Starting");
}
void loop(void) {
}
Thank you for your support up to here.
