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.

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.

[Fleischtorte]

@Anticimex okay, thanks for the fast response :+1:

[alexsh1]

@scalz Did you manage to do the 3D case for the PA LNA transceiver for the sensebender gateway please?

@Anticimex said in 💬 Sensebender Gateway:

MY_CORE_ONLY

Just curious, what does "MY_CORE_ONLY" do? The library mentioned that it should be enabled " if you want to use core functions without loading the framework" . What are the core functions and what is the framework?

[Anticimex]

@ted core functions are things like the HAL and debug logging functionality. Framework means all the presentation message transmissions and handshaking. Basically, MY_CORE_ONLY allow you to leverage the functionality provided by the library without having the library execute things out of your control.

@alexsh1
woops, yes i made it but forgot the upload. it's now uploaded here https://www.mysensors.org/hardware/sensebender-gateway#design-files

Enjoy :)

[alexsh1]

@scalz Thank you.

Does anyone have the PA transceiver version with Sensebender Gateway?
Any feedback please?

[tbowmo]

@alexsh1

If you mean using a nrf24 with lna/pa, with the gateway. Then yes.. I have had it running for some months now.

Anything in particular that you want to know?

[alexsh1]

@tbowmo yes, that's what I meant
I am thinking about installing either a normal nrf24l01+ or lna/pa version. I have had some issues with power in the past with the lna/pa transceiver.
What's your experience? What kind of power supply do you use? How better is the coverage?

[tbowmo]

I haven't checked if the coverage is any better with the lna/pa version, compared to standard modules.

Currently the gateway is connected to a RPI2, which in turn is powered by a 2A powersupply from RS Components

I haven't had any issues with it yet, but then again.. I mainly receive data from sensor nodes, and not that much sending data to distant nodes from the gateway

[alexsh1]

@tbowmo It is probably not Sensebender topic, but more lna+pa range one.
I am not sure about my RPi3 as though it is powered by the 3A PSU, I have a USB z-wave stick, three transceivers, one UPS Plco (as HAT) and a 20x4 screen. I lot of power is consumed so not sure adding yet another one. (lna+pa is power hungry during peaks).

I'll get the nrf24l01+ lna+pa ordered and test the range. In my view rfm69 range is probably better, but I have the rfm69 gateway on moteino with a trace antenna (very small footprint and it is based on ATMega1284P so 128KB sketch flash memory - more than I need).

@hek - is it the intention to combine rfm69 and nrf24l01+ gateways in one in the future?
I understand Sensebender GW is ready for it, but it is more a software limitation???
I am really looking forward to combined GW.
I also have a separate one for rfm95 so that I can use some remote sensors.

[hek]

No, I haven't heard of any near plans in the core team about doing multi radio/sub-network support in 2.0.

This requires some extra thoughts and would probably only fit on SAMD/ESP nodes.

[alexsh1]

@hek Which is good as the Sensebender GW is based on SAMD! So it is ready to be the first 2-in-1 GW.
Anyway, keep on doing a great work! I'll patiently wait until the combined GW is there.

[NiklasO]

Ordered from ITEAD. Nice to get rid of this stuff:

Just nudging anything result in problems. ;-)
Time to fire up the 3D-printer.
