i try the esp8266 + hm10 + dht22 combo, but i cant get any messages from hm10, the dht22 works great, the pins are correct, do i missing something? i need flash hm10 with something or just connect the pins and it should work?
i read the guide, the differences are : the nodemcu is v3, i connected the hm10 directly on nodemcu , and i bought the hm10 in my city but the model seems to be the same from bangood. the serial monitor read is this:
Sending Hum to MQTT
Sending Temp to MQTT
Did you checked your hm10 firmware version?
no, what firm need to be? and how can i check?
From the guide ;-):
the HM10/11 firmware version must be >= v601
how can you check, with a ftdi USB/TTL, here is the HM10 guide:
