Will messages be stored temporarily, until a PyGo has contacted another node for a certain amout of time and then hop the stored message? Thinking of eg. communication net between busses or so.

If your going to have a physical button to enable it to be reconfigured you dont have many options. An idea may be to write something to flash storage after the first time its been configured and not allow additional setup attempts unless that file is removed but if someone has physical access to the device there's nothing stopping them connecting over uart and removing it via repl. Alternatively. A physical preventative might be more suitable (lock it in a box)

@dan I finally made it work! But only because of your advice! Thank you so much!!!

@jcaron as of right now what I want to achieve: Using a SCD30 sensor (which gets humidity, temperature and CO2 levels) read the data and save it, for that I intend to create (or modify based on other libraries) the library for the sensor. I already have the adress of the sensor and the hexadecimal "commands" and I am trying to use the libraries of the Pysense sensors as a template

Hi! You can use this command line tool: https://hackmd.io/s/HJhUcamxQ#

@juan_peroza JSON is not a protocol, it’s just a data representation. You can send whatever you want, but JSON is not very space efficient, and is usually not the best choice for data sent over a (very) low bandwidth link such as LoRa, SigFox, NB-IoT, or BLE. It’s usually better to use an optimised binary format in those cases.

D not forget LoRa as an option if it is a LoPy 4 device.

Hi @Martinho and @robert-hh, Indeed that's missing from the docs, I've updated the page. Thanks for pointing it out!

@robert-hh said in Wipy 2.0 and save data on my pc, not in flash memory: Which BN055 module I was asking about the vendor and make of the BNO055 board.

Hi @stefan85e, You can find our example project for the Pysense on GitHub here. It has the main.py with the code and the libraries.

Hey @timh , I have mentioned about the sensor, I am going to use for monitoring and I want to use cellular service, as wifi connection is not available here so not sure about which hardware will be better to use and if I try with GPY then need to know the better way to connect the Private network with GPY which help readings of sensor on AWS cloud And I am new comer to this area so please suggest the tools of AWS cloud which I should use to make this monitoring process display on my smart phone.

@kebson Thinking about your message, I assume that you connected the collector of the transistor to GND and control the relay though through the Vcc & GND pins of that relay board. Two topics are to be discussed: Current draw. According to the data sheet, the coil resistance is 70 Ohm, resulting in an current of 47 mA at 3.3V. At that load, the output voltage should be lower than 3.3 V, so it might "just" fit. At about 3V, the force at the relay contacts may be lower than at 5V, causing higher relay contact wear. Flyback voltage peaks. If you did not remove the flyback diode from the board, that might work, at least for a while. But still I would not consider to connect an inductive load directly to the ESP32 output pins. It may work for a while, but then break. B.T.W.: What is the mains voltage/power of the Pump?

LoRaWAN is using a non-licensed shared frequency band. As long as you meet local regulations, e.g. in Europe max. 1% transmit duty cycle, do not exceed transmit power and bandwidth limits you are safe. It is not about LoRaWAN it is about local radio regulations. These rules are the same for single and 'normal' multi channel GW's.
