Hello bootloader support ATMEGA328PB now this uC is cheaper than 328p? Best regards

Hi, how I can using indication LEDs using I/O expander, because I don't have free pins on my MCU.

mcp.begin();
mcp.pinMode(0, OUTPUT);
mcp.digitalWrite(0, HIGH);

Hello I bought on aliexpress, 20 pcs of ATmega328p-au
5 pcs with marking ATMgea328P U-TH and 5 with marking U-PH
I solder all ten to node project with sleeping mode, use Minicore and this settings to burn bootloader
Internal 8MHz, Bod: Disabled.
Nodes with U-PH Atmega charge just 7uA and this repetitive current for this project. But every node with U-TH charge 250-750uA quick changes. Node working ok. Has anyone had a similar problem with ATmegas? Regards

It's very old instruction, OpenHab not support MySensors, I have to compile library someone has working step for this?

I use this hardware, I dont connect radio directly to my RPi, but throught Arduino..
https://www.mysensors.org/build/serial_gateway

Radio connection is realy ok, when I switch console to minicom init is ok and i find my nodes.

Hi , I try use serial gateway on my rpi
I use this instruction, https://forum.mysensors.org/topic/6694/openhab-2-4-mysensors-serial-gateway-how-to-install
but when I start mysgw, gateway not run correctly

pi@raspberrypi:~/MySensors $ sudo ./bin/mysgw

In Arduino IDE Serial port, gateway work correctly in rpi using minicom too.

Hello, I use NRF24L01 and sleep() after mag(), if gateway NRF24 is not active node is not going to sleep mode. I should use MY_REGISTRATION_RETRIES or another option?

Hello, try --my-transport=nrf24
