The BALLOON Project of LoRa

I think the best option is the lora satelite we have allready contacted laguna company waiting for their respond the second idea is to take the board this and basically switch the communication device from APRS ro lora simple but really very complicated but is possible :):):

Basically RAK can provide us with a custom vesrion of their board and also techical support - the Rak triobisba very good solution for our project if we modify it a bit :) instead of desing a pcb from scratch:):

On your screenshot, go to the output menu and tick “create hex file”, the you will have the bin file created during compilation

Awesome, nice work. 100 km is a good start

Are they any ways to visualize the data ?

kastayou · March 22, 2019, 8:54pm

What kind of visualisation are you looking for?

Cayenne is one way to visualise the data.
You have the csv file, you can you this file to draw some chart on Microsoft Excel or similar software.
Another way would be to connect directly to TTN MQTT and use node-red to visualize the data.

I have seen that you reached an altitude of 12000 meters, that’s great!

Here is a chart of altitude versus time based on your data.

Basically on the time of the expirament cayennes my device dident work and some time it gets stuck also ttn has a problem when you try to log in - a like this free services but we will show this expirament in front of 1.000 students what if in the day of the expirament cayene or ttn have problem again can you recommend a better morr reliable service ?

Hobo · March 23, 2019, 7:22am

Perhaps, Grafana, Kibana?
By the way I saw no GPS data in the CSV, did I miss it?

elpis · March 23, 2019, 7:33am

The gps condinated are there for sure

I have found cayenne mydevices very reliable. I am surprised to see that it did not work.

You should have a look at node red. You can easily create a dashboard and retrieve the data from TTN by MQTT. Lot of information are available online.

Kibana or Grafana are also an option.
I found Grafana easier to use.

You can also have a look at application integration available in TTN.
