Posted August 27, 2026 at 4:22 am · in GPS, GSM modülü ve toz sensörü: üç seri cihazı tek Raspberry Pi’ye nasıl bağlarım? #7

Sonunda üçü birden çalışıyor! uart3 bende /dev/ttyAMA3 olarak geldi, PMS5003 oradan okunuyor. Modem için udev kuralı yaptım, interface 02 değil 03 çıktı bende, onu düzeltince oturdu. Chrony’yi de kurdum. Çok teşekkür ederim 🙏

Haklısınız, kartın üstünde micro USB var, hiç aklıma gelmedi. Onu USB’ye taktım, /dev/ttyUSB2 diye bir şey çıktı.

Translated from Türkçe by AI ·

I tried Wi-Fi RSSI at home, and even a phone jumps from room to room, so I think you shouldn’t go there at all.

Does it happen when you run it with sudo? It happened to me too.

Translated from Türkçe by AI ·

I asked around, and the gateway is 868. I got an RFM95W 868 and a 3.3V Pro Mini, and selected CFG_eu868. I had also typed the DevEUI backwards, and after correcting it the second attempt gave EV_JOINED, and the join shows up in the frames log. The old Ra-02 has probably really burned out too, it doesn’t respond at all anymore 😅

I don’t know, I think it says 433 on the box. The gateway was set up by friends, I’ll ask them.

Translated from Türkçe by AI ·

Done! Flask is running on the Pi, and the page polls every 30 seconds. At first I got a 401, I had forgotten to put “Bearer ” in front of the key. Also, the house IP is dynamic: the IP I wrote in the allowlist changed the next day, so I left it empty for now. I’ll ask the modem for a static IP.

You’re right, I hadn’t thought of that. The page was already sitting on GitHub Pages 😬 I deleted the token. So how should I do it now?
