Sends on every message, only when it changes. Attribute messages have a separate per-device limit, lower than telemetry.

I set up the bt-agent service plus a button-triggered 2-minute window, and pairing now works without issues. The getty problem was exactly as you said: the -C was missing, and rfcomm was throwing an “sdp” error, I was looking for the error in the wrong place. Thanks.

Sağ olun. Single channel fikrinden vazgeçtim, SX1302’li bir HAT aldım, eski Pi 3’e taktım, Basics Station ile bağladım. 6 düğümü LMIC ile OTAA’ya geçirdim, hepsi ilk iki denemede join etti. Önce raw hex geldi, kendi codec’imi yazınca sıcaklık ve nem ayrı anahtarlar olarak düştü. Paket kaybı neredeyse sıfır.

The line ending really is , I checked with hexdump. The port problem is also solved with by-id. Now I just send stable readings once a second, and it has been running without issues for 2 days with systemd. Thanks.

It works, thanks. The ESP32 wasn’t actually subscribed to v1/gw/rpc, and I had put the command in the gateway’s profile. I added 6 sliders, each one bound to its own child. Also, the slider only sends when released. I thought it was sending on every movement and was getting ready to write a queue on the ESP32, but it’s not needed now.

I defined it. light.set, with parameter level. I first set the Tier to Privileged, got the “This command cannot be sent from a board” error, then moved it to Basic. But when I select the child device, the command doesn’t go out, it stays at Sent.

The permission problem is gone after adding the user to dialout, thanks. But I have two new issues: after rebooting the Pi, sometimes the scale indicator becomes ttyUSB1 (there is also a USB-RS485 on the same Pi), and readline sometimes waits forever, with nothing being printed. The indicator data does flow in a terminal program, though.

Automatic level shifters like TXS0108 sometimes cause problems on SPI, I use a 74LVC245 or a resistor divider. Cleaner is a 3.3V board.

Haklısınız, ikisi birden. Seviye dönüştürücü taktım, callback’i bayrağa çevirdim. İlk modül gerçekten bozulmuş, yenisini takınca iki gündür hiç kesilmeden alıyor. CS konusunu da kontrol ettim, shield 10 numarayı, LoRa 53’ü kullanıyor. Teşekkürler Derya Hanım.
