Call to arms | Teensy + WiFi = true

mjs513 · Aug 29, 2026

@wwatson - just a quick thought maybe add a longer delay after issuing the reset command? Now sure what it is now.

wwatson · Aug 29, 2026

Found it

The other examples have the wrong pin settings and the wrong Serial port. changed that on on of the other sketches and it works. Got errands to run so I can't test the other two until later...

Actually fairly simple where you don't even need to make use their brick:

Probably will play a bit more with this tomorrow.

Thanks @mjs513 - I have this stuff already working on Q, what I am wondering about is how to get this to work on
the T4.1 with this Wifi adapter

WIth a little help I have something that does a little:

Code:

#include <QNEthernet.h>

using namespace qindesign::network ;

const char *server = "geocoding-api.open-meteo.com";
const int port = 80;
const char *resource = "/v1/search?name=DisneyLand";
constexpr uint32_t kDHCPTimeout = 15000;  // 15 seconds

EthernetClient client;

void setup() {
  Serial.begin(115200);
  while (!Serial && millis() < 4000);

  // Initialize Ethernet (DHCP)
  if (!Ethernet.begin()) {
    Serial.println("Failed to configure Ethernet using DHCP");
    return;
  }

  uint8_t mac[6];
  Ethernet.macAddress(mac);  // This is informative; it retrieves, not sets
  printf("MAC = %02x:%02x:%02x:%02x:%02x:%02x\r\n",
         mac[0], mac[1], mac[2], mac[3], mac[4], mac[5]);

  printf("Waiting for local IP...\r\n");
  if (!Ethernet.waitForLocalIP(kDHCPTimeout)) {
    printf("Failed to get IP address from DHCP\r\n");
    return;
  }

  IPAddress ip = Ethernet.localIP();
  printf("    Local IP    = %u.%u.%u.%u\r\n", ip[0], ip[1], ip[2], ip[3]);
  ip = Ethernet.subnetMask();
  printf("    Subnet mask = %u.%u.%u.%u\r\n", ip[0], ip[1], ip[2], ip[3]);
  ip = Ethernet.gatewayIP();
  printf("    Gateway     = %u.%u.%u.%u\r\n", ip[0], ip[1], ip[2], ip[3]);
  ip = Ethernet.dnsServerIP();
  printf("    DNS         = %u.%u.%u.%u\r\n", ip[0], ip[1], ip[2], ip[3]);

  printf("\r\n");



  Serial.print("Local IP: ");
  Serial.println(Ethernet.localIP());

  // Connect to server
  if (client.connect(server, port)) {
    Serial.println("Connected to server. Sending request...");

    // Send HTTP GET Request
    client.printf("GET %s HTTP/1.1\r\n", resource);
    client.printf("Host: %s\r\n", server);
    client.println("User-Agent: Teensy-QNEthernet");
    client.println("Connection: close");
    client.println();
  } else {
    Serial.println("Connection failed.");
  }
}

void loop() {
  // Read response stream
  while (client.available()) {
    char c = client.read();
    Serial.write(c);
  }

  // If server disconnects, stop client
  if (!client.connected() && !client.available()) {
    client.stop();
  }
}

@KurtE - If you don't mind I would like to add your example to my Ethernet examples repo on GitHub.
I checked the other two Bluetooth examples and they also seem to work. It is really interesting that this all works without the flow control signals. once we get the new boards with the working RTS/CTS the Serial baud rate will go from 115200 to 3000000. It shows some foresight on there part. Without the flow control signals the 3000000 baud rate might not work.
I have to get up at 3:00 AM tomorrow morning so it's

wwatson · Aug 30, 2026

Here is the temporary working Sparkfun Teensy Bluetooth library:

https://github.com/wwatson4506/SparkFun_Teensy_Bluetooth/tree/Updated

.
To use the two pins of the inverter must be shorted together as per post #335. Flow control has been disabled in each of the four sketches. the Bluetooth scan function has been verified to be working with my laptop Bluetooth monitor. How the rest of the examples are supposed to work well, I really don't know yet

Those with steadier hands than mine should be able to solder bridge the two pins on the inverter easier than I was able to...

For some reason I have a fat round tip on the iron - and using a mag lens/light I just did a touch of preheat then touched again on thin solder strip end and it was done?
Not sure why I don't get past #4 to #5?

@defragster - Not sure why it is not working for you. I'll download the library on another desktop and make sure it is working. In the mean time here is the scan sketch in full:

It also worked with Arduino IDE 2.3.10 and TD0.65. One thing I did notice was the Sparkfun_Teensy_Bluetooth library was showing up in the "INCOMPATIBLE" portion of the examples menu on Arduino 1.8.19. Not sure why...

wwatson · Aug 30, 2026

Just for the heck of it I started up my windows machine and tested the library on it. It worked there as well

I am going to find out why the library is showing up in the "INCOMPATIBLE" portion of the examples menu...

defragster · Aug 30, 2026

In Examples as Incompatible here as well after restarting IDE 1.8.19.

Rebuilt using lib from github and again stalls at #4? Is the solder bad or wrong? Anything else needed?

Downloaded as ZIP and overwrote folder and it is the only LIB shown:

How is the SFun PCB connected to T_4.1?

Here it is the PJRC PCB with three parallel header sets. T_4.1 in one and SFun PCB in the next over - so 1.5" of routed wires that works fine for SDIO WiFI?

My setup sounds the same as yours except my board had the inline female sockets with long male pins solder to it, post #298...

defragster · Aug 30, 2026

wwatson said:

Yes, the same!

I did solder the wrong chip first and that made the T_4.1 not boot (thus my RED comment). Might have damaged something - but the WiFI scan still works.

Don't do this assuming it was the right three legged side when it is the SMALLER part shown in prior pics p#360. Yes, using eyes - and magnification - is important. ... the p#335 simulated RED board image left for guess work here

Just swapped the T_4.1 (from the olde days of heat sink testing) with a fresh one and same result.

Just swapped the T_4.1 (from the olde days of heat sink testing) with a fresh one and same result.

Dang, I think that other IC is the added voltage regulator

I did not catch that at first. The inverter chip is the one next to the CYW43439 chip and the RX pin label. Unfortunately they look the same

Yes, seems like

. Plugged it in and it didn't show up? SFun PCB oddly warm as a short will do - closer look beyond the OBVIOUS chip to find the MUCH SMALLER ONE harder to see at less than half the size.

Better light and magnification found the right one - but the obvious one was easier to find and solder

@KurtE - If you don't mind I would like to add your example to my Ethernet examples repo on GitHub.
I checked the other two Bluetooth examples and they also seem to work. It is really interesting that this all works without the flow control signals. once we get the new boards with the working RTS/CTS the Serial baud rate will go from 115200 to 3000000. It shows some foresight on there part. Without the flow control signals the 3000000 baud rate might not work.
I have to get up at 3:00 AM tomorrow morning so it's

We probably can and should add some examples like this. @mjs513 and I were hacking away on one that actually retrieves the
Weather information. There are still problems with my most recent one where I tried to merge the earlier sketch that retrieved the
Lat/Long of city names and then used that to talk to the calls to retrieve the weather information.

Currently I have it default to something like Disneyland and returns data like:

If we were to make something like this as an example, we should probably put several comments in it giving credit to
things like: Your Friently AI, open-meteo.com, Not sure also mention Arduino with their Brick as a starting point...

But now just having some fun
