A student organization of the University of Stuttgart, <a href=\"https:\/\/www.ksat-stuttgart.de\/de\/homepage\/unsere-projekte\/bubble\/\">KSAT<\/a>, launched a balloon experiment &#8212; and with it, a LoRa experiment of mine. Unfortunately, I had to work and no time to be present for the launch campaign. And so I was not there to ensure that my LoRa payload on the balloon was running all right. The\u00a0 probe took off with the Lora payload failing right from the start.<\/p>\n<p>The probe flew for about 3 hours and\u00a0 landed somewhere in a field near Kraichtal @ 49.110380N 8.770114E. A video is available on <a href=\"https:\/\/www.youtube.com\/watch?v=a8CUPK3FvSw\">youtube<\/a>. Lacking the suitable gear to track the signal, I had to rely on Christian to get the landing position and arrived as last one about 30 minutes after the landing. The log of the balloon probe showed that there were several power cycles during the launch campaign. With the last power cycle, the raspberry started up, but the Lora payload did not sent. The root cause I could not determine. Starting the payload up at home, it worked all right. Lesson learned: If you want it to work, you better test like a berserk!<\/p>\n<p>\u00a0<\/p>\n<figure id=\"attachment_6015\" aria-describedby=\"caption-attachment-6015\" style=\"width: 1920px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/www.gloetzner.net\/wordpress\/wp-content\/uploads\/2021\/11\/20200921_IMG_2526-scaled.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-6015\" src=\"http:\/\/www.gloetzner.net\/wordpress\/wp-content\/uploads\/2021\/11\/20200921_IMG_2526-scaled.jpg\" alt=\"\" width=\"1920\" height=\"2560\" srcset=\"https:\/\/www.gloetzner.net\/wordpress\/wp-content\/uploads\/2021\/11\/20200921_IMG_2526-scaled.jpg 1920w, https:\/\/www.gloetzner.net\/wordpress\/wp-content\/uploads\/2021\/11\/20200921_IMG_2526-225x300.jpg 225w, https:\/\/www.gloetzner.net\/wordpress\/wp-content\/uploads\/2021\/11\/20200921_IMG_2526-1602x2136.jpg 1602w, https:\/\/www.gloetzner.net\/wordpress\/wp-content\/uploads\/2021\/11\/20200921_IMG_2526-113x150.jpg 113w, https:\/\/www.gloetzner.net\/wordpress\/wp-content\/uploads\/2021\/11\/20200921_IMG_2526-768x1024.jpg 768w, https:\/\/www.gloetzner.net\/wordpress\/wp-content\/uploads\/2021\/11\/20200921_IMG_2526-1152x1536.jpg 1152w, https:\/\/www.gloetzner.net\/wordpress\/wp-content\/uploads\/2021\/11\/20200921_IMG_2526-1536x2048.jpg 1536w\" sizes=\"(max-width: 1920px) 100vw, 1920px\" \/><\/a><figcaption id=\"caption-attachment-6015\" class=\"wp-caption-text\">Bubble2.
