\u00a0\u00a0 Softwarov\u00fdch \u0159e\u0161en\u00ed pro pr\u00e1ci s APRS je mnoho, j\u00e1 jsem si obl\u00edbil Direwolf. Nen\u00ed to jenom softwarov\u00fd TNC modem, Je to \u0159e\u0161en\u00ed nejen pokud chceme postavit APRS tracker do auta, ale i komplexn\u00ed n\u00e1stroj pro vytvo\u0159en\u00ed infrastruktury APRS s\u00edt\u011b. Jeho tv\u016frce John WB2OSZ si m\u00e1knul a d\u00edky jeho pr\u00e1ci, my m\u00e1me zase n\u011bco na hran\u00ed. Obs\u00e1hl\u00e9 informace, v\u010detn\u011b manu\u00e1lu a spousty dal\u0161\u00edm materi\u00e1l\u016f najdete zde<\/a>.
\n\u00a0\u00a0 Direwolf um\u00ed b\u00fdt jen jednoduch\u00fd tracker, kter\u00fd bude prost\u0159ednictv\u00edm p\u0159ipojen\u00e9 radiostanice, pos\u00edlat polohu va\u0161eho auta (hamshacku nebo \u010dehokoliv co pot\u0159ebujete) do APRS r\u00e1diov\u00e9 s\u00edt\u011b a pokud v\u00e1\u0161 paket zachyt\u00ed infrastruktura i do internetov\u00e9 APRS-IS s\u00edt\u011b.

Um\u00ed b\u00fdt iGatem, kter\u00fd nejenom roz\u0161\u00ed\u0159\u00ed oblast pokryt\u00ed APRS stejn\u011b jako digipeater, ale zachycen\u00e9 pakety rovn\u011b\u017e p\u0159epo\u0161le do internetov\u00e9 APRS-IS. A naopak z internetu m\u016f\u017ee vys\u00edlat t\u0159eba zpr\u00e1vy, po\u010das\u00ed, e-maily atd..<\/span><\/p>\n

N\u00e1sleduj\u00edc\u00ed postup pop\u00ed\u0161e jak Direwolf nainstalovat, propojit s radiostanic\u00ed a nastaven\u00ed konfigura\u010dn\u00edho souboru. Postup je stejn\u00fd jak pro mobiln\u00ed\/p\u0159enosnou APRS sestavu, tak i pro stavbu digipeatru a iGatu.<\/p>\n

\u00a0\u00a0 Co budete pot\u0159ebovat:
\n\u00a0\u00a0 –\u00a0 n\u011bjak\u00fd jednodeskov\u00fd po\u010d\u00edta\u010d. Raspberry PI, Orange PI, Banana PI apod..
\n\u00a0\u00a0\u00a0\u00a0 (osobn\u011b m\u00e1m instalace vyzkou\u0161en\u00e9 se v\u0161emi uveden\u00fdmi.)
\n\u00a0\u00a0 – radiostanici VHF pro kmito\u010det APRS 144,800MHz.
\n\u00a0\u00a0 – USB zvukovou kartu pro Raspberry PI.
\n\u00a0\u00a0 – DC\/DC m\u011bni\u010d 12V\/5V pro nap\u00e1jen\u00ed Raspberry PI.
\n\u00a0\u00a0 – konektory pro propojen\u00ed zvukov\u00e9 karty s radiostanic\u00ed.
\n\u00a0\u00a0 – opto-izol\u00e1tor pro PTT p\u0159ipojen\u00ed (pokud se objev\u00ed probl\u00e9my p\u0159i propojen\u00ed radiostanice a RPi).
\n\u00a0\u00a0 – pokud budete cht\u00edt Direwolf pou\u017e\u00edvat jako autonomn\u00ed tracker, budete pot\u0159ebovat i GPS modul.<\/p>\n

Propoj\u00edme v\u0161e podle obr\u00e1zku. Pou\u017eil jsem Motorolu \u0159ady GM3XX.
\n\"propojen\u00ed<\/a><\/span>P\u0159iprav\u00edme si Raspberry PI pro instalaci Direwolfu. Zde naleznete n\u00e1vod na p\u0159\u00edpravu microSD karty s opera\u010dn\u00edm syst\u00e9mem<\/a>. J\u00e1 pou\u017e\u00edv\u00e1m Lite verzi Raspberry PI OS bez grafick\u00e9ho rozhran\u00ed s p\u0159\u00edkazovou \u0159\u00e1dkou. \u0160et\u0159\u00ed to prost\u0159edky procesoru a stejn\u011b se bude jednat o jedno\u00fa\u010delov\u00e9 za\u0159\u00edzen\u00ed. Po instalaci bude ve\u0161ker\u00e1 interakce se za\u0159\u00edzen\u00edm na d\u00e1lku p\u0159es ssh<\/a>. <\/p>\n

Pokud u\u017e Raspberry pou\u017e\u00edv\u00e1te a v\u00e1\u0161 OS je Raspbian zalo\u017een\u00fd na Debianu 10 \u010di star\u0161\u00edm, m\u016f\u017eete instalovat Direwolf p\u0159\u00edmo z repozit\u00e1\u0159\u016f p\u0159\u00edkazem:<\/p>\n

\u00a0\u00a0\u00a0\u00a0\u00a0 sudo apt install direwolf<\/p>\n

<\/em>pokud m\u00e1te novou instalaci, mus\u00edte zvolit jin\u00fd postup. Aktu\u00e1ln\u00ed verze Direwolfu v repozit\u00e1\u0159\u00edch nepodporuje pr\u00e1ci s GPIO na Raspberry PI OS s Debianem 11 a 12.Je pot\u0159eba st\u00e1hnout developerskou verzi, ve kter\u00e9 tato podpora je.
\nNe\u017e za\u010dneme, nainstalujte si na RPi v\u0161e pot\u0159ebn\u00e9:<\/p>\n

\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 sudo apt update && sudo apt upgrade -y<\/em>

Pokud v\u0161e prob\u011bhlo bez chyb je Direwolf nainstalov\u00e1n.<\/p>\n

Konfigura\u010dn\u00ed soubor direwolf.conf<\/a> je hoooooooodn\u011b dlouh\u00fd. Direwolf je opravdu velmi univerz\u00e1ln\u00ed program pro APRS s mnoha funkcemi, tomu odpov\u00edd\u00e1 i velikost konfigura\u010dn\u00edho souboru.
\nVytvo\u0159\u00edme si vlastn\u00ed jednoduchou konfiguraci pro digipeater, kter\u00fd bude opakovat p\u0159ijat\u00e9 pakety a pravideln\u011b bude odes\u00edlat svou polohu.<\/p>\n
