[tekka]

@TheoL yeah, almost 4mo ago - good to have you back 👍

[TheoL]

@tekka life is really busy. But I'm working on some new MySensors idea's I'd like to try out. But for now on my way to the postal office. Can't wait.

[tmn103]

Is there any way of getting the MQTT Ethernet gateway working on this yet?

[tbowmo]

@tmn103

I haven't tried myself, but it should be the standard GatewayW5100MQTTClient sketch, without modifications. (the GatewayW5100 sketch is running without modifications already)

[tmn103]

Just tried the MQTT gateway sketch and got some strange behaviour.

Seems to pick up one of the nodes, but can't get an ip address or mqtt connection.

Any ideas on what to try?

Still can't get the mqtt gateway to work. Has anybody managed to?

[Fabien]

Just try standard GatewayW5100MQTTClient sketch. It works fine with RFM69HW
On your log you seems to have issue with your IP. Just my log :

I would triple-check the IP addresses that you are using...

 */

/**
 * @example SecurityPersonalizer.ino
 * This sketch will personalize either none-volatile memory or ATSHA204A for security functions
 * available in the MySensors library.
 *
 * For ATSHA204A:
 * It will write factory default settings to the configuration zone
 * and then lock it.<br>
 * It will then either<br>
 * -# Generate a random value to use as a key which will be stored in
 * slot 0. The key is printed on UART (115200) in clear text for the user to be
 * able to use it as a user-supplied key in other personalization executions
 * where the same key is needed.
 * -# Use a user-supplied value to use as a key which will be stored in
 * slot 0.
 * Finally it will lock the data zone.
 *
 * By default, no locking is performed. User have to manually enable the flags that
 * turn on the locking. Furthermore, user have to send a SPACE character on serial
 * console when prompted to do any locking. On boards that does not provide UART
 * input it is possible to configure the sketch to skip this confirmation.
 * Default settings use ATSHA204A on @ref MY_SIGNING_ATSHA204_PIN.
 *
 * For Soft signing:
 * It will<br>
 * -# Generate a random value to use as a key which will be stored in EEPROM.
 * The key is printed on UART (115200) in clear text for the user to be ablle to
 * use it as a user-supplied key in other personalization executions where the same
 * key is needed.
 * -# Use a user-supplied value to use as a key which will be stored in EEPROM.
 * -# Generate a random value to use as a serial number which will be stored in EEPROM.
 * The serial number is printed on UART (115200) in clear text for the user to be ablle to
 * use it as a user-supplied serial number in other personalization executions where the
 * serial is needed (typically for a whitelist).
 * -# Use a user-supplied value to use as a serial which will be stored in EEPROM.
 *
 * For Encryption support:
 * -# Generate a random value to use as a AES key which will be stored in EEPROM.
 * The AES key is printed on UART (115200) in clear text for the user to be ablle to
 * use it as a user-supplied AES key in other personalization executions where the
 * AES key is needed (typically for RF encryption).
 * -# Use a user-supplied value to use as a AES key which will be stored in EEPROM.
 *
 * Personalizing EEPROM or ATSHA204A still require the appropriate configuration of the
 * library to actually have an effect. There is no problem personalizing EEPROM and
 * ATSHA204A at the same time. There is however a security risk with using the same
 * data for EEPROM and ATSHA204A so it is recommended to use different serial and HMAC
 * keys on the same device for ATSHA204A vs soft signing settings.
 *
 * Details on personalization procedure is given in @ref personalization.

.... i have cut the rest of code because its to long to post here complete ...

but i dont get any output on serial monitor. Do you know whaat is went wrong?
thanks

[Anticimex]

@meddie it is a limitation of the current personalizer that it does not inherit the baud rate from the library settings. It is stuck to 115200. (can be changed of course). It will be fixed in the next personalizer update. Perhaps you expect a different baud rate?
See

Serial.begin(115200);

[meddie]

yes i have seen this an my console is set to 115200 bauds, but no output

[Anticimex]

Hm. Then I don't know what's wrong. I have not yet used that hardware.

[meddie]

i just get the output, the serial console must be open while uploading the sketch, immedialty after the upload i see the output.
But all Keys are FFFFFFF

SOFT_HMAC_KEY | FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF
SOFT_SERIAL   | FFFFFFFFFFFFFFFFFF
AES_KEY       | FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF
ATSHA204A DATA:

Why this?

[tbowmo]

The personalizer doesn't wait for the usb port to be enumerated / attached. We need to add the following code in the start of setup() (if I remember right)

While(! Serial()) {} 

But only for devices using native USB (I thought that I had added it already, but I might be wrong)

[Anticimex]

@tbowmo ah, I will add that then for samd targets. The personalizer uses MY_CORE_ONLY so your line perhaps is not run.

[tbowmo]

@Anticimex
I think something in the line of

#if defined(ARDUINO_ARCH_SAMD)
while (!Serial) {} // halts operation until something attaches to the USB device
#endif

above, is based on hwInit function in MyHwSAMD.cpp

[Anticimex]

@tbowmo Yep, I have already (locally) done this:

#if defined(ARDUINO_ARCH_SAMD)
	while(!Serial()); // Wait for USB enumeration before setting up serial device
#endif
	Serial.begin(MY_BAUD_RATE);

[Anticimex]

I have moved the signing specific discussion in this thread here where it belongs.

[Fleischtorte]

hi all,

i have some problems to enable encryption on the gateway. When i upload the cleareeprom sketch, the gateway dont clear the eeprom,
the same problem comes up when i want to set the ENC-Key. Both sketches work with my moteino-gateway and my ProMini-Node, so do i miss something with the SensebenderGW-Config?

ClearEEPROM:

#if defined(ARDUINO_ARCH_SAMD)
while (!Serial) {} // Wait for USB enumeration before setting up serial device
#endif
  Serial.begin(MY_BAUD_RATE);
	Serial.println("Started clearing. Please wait...");
	for (int i=0; i<EEPROM_LOCAL_CONFIG_ADDRESS; i++) {
		hwWriteConfig(i,0xFF);
	}
	Serial.println("Clearing done. You're ready to go!");

Set ENC-Key:

 #if defined(ARDUINO_ARCH_SAMD)
 while (!Serial) {} // Wait for USB enumeration before setting up serial device
 #endif
  Serial.begin(MY_BAUD_RATE);
  Serial.println("Set ENC-Key. Please wait...");
    uint8_t key[32];
    memcpy(key, user_aes_key, 16);
    hwWriteConfigBlock((void*)key, (void*)EEPROM_RF_ENCRYPTION_AES_KEY_ADDRESS, 16);
    Serial.println("Set ENC-Key. Done");

[Anticimex]

@Fleischtorte we have confirmed a bug in the I2C eeprom management in the samd platform. A fix is in the works.
