Trying to use OTA - not visible in mDNS
Posted: Wed Feb 07, 2018 7:18 amI managed to get the basic OTA example code working on an ESP-07 with a custom breakout board, and to the point where I could easily flash my own firmware over our local network. I then tried to flash the code to a bunch of other boards, but I've not been successful. The rest of the firmware works - I'm streaming sensor data using MQTT, so I can connect to our WiFi and the MQTT broker, etc. What doesn't work is the OTA.
I'm using platformio and my ini is:
The OTA setup code is below. The rest of the code works, so I assume the issue is here:
This doesn't work, even with the Basic OTA example. The chip outputs something like this on boot:
So it's connecting to the WiFi, has an IP address and OTA is configured. However there doesn't seem to be a way of checking if the mDNS service is actually working - aside from seeing if it pops up in platformio's device manager.
Since it did work on the first prototype, what could be different? The firmware is flashed OK, so I don't think it's an upload error. Perhaps the other modules have a different config somehow? (Do I need to upload a different bootloader?)
I'm using platformio and my ini is:

// NOTE: if updating SPIFFS this would be the place to unmount SPIFFS using SPIFFS.end()
Serial.println("Start updating " + type);
});
ArduinoOTA.onEnd([]() {
Serial.println("\nEnd");
});
ArduinoOTA.onProgress([](unsigned int progress, unsigned int total) {
Serial.printf("Progress: %u%%\r", (progress / (total / 100)));
});

String hostname = "sensor_" + chip_id;
ArduinoOTA.setHostname(hostname.c_str());

}This doesn't work, even with the Basic OTA example. The chip outputs something like this on boot:

So it's connecting to the WiFi, has an IP address and OTA is configured. However there doesn't seem to be a way of checking if the mDNS service is actually working - aside from seeing if it pops up in platformio's device manager.
