Hi Aaron.Lee, I already tried the LoRa Sender code and it worked perfectly. Now I want to connect the CubeCell HTCC AB-01 node to TTN but I have not succeeded. I generated the same Device EUI, Application EUI and App Key in the node (with the code LoRaWan_downlinkdatahandle.ino) and in TTN.
I send screenshots as evidence. What should I do? How should I do it?
I would also like to ask something else: yesterday I soldered the pin rule to the board, then connect the HTCC module to the USB port of the pc and the led next to the microUSB input turned on normally, I also measured the voltage of the pins: Vs = 5VDC, 3V3 = 3.3VDC, VIN = 5 VDC, Ve = 0VDC, then I tried the Hello World code again and it worked fine. But today I connected the HTCC AB-01 module to the USB port of the pc and the LED next to the microUSB input of the LoRa module did not light up, I uploaded the Hello Wolrd code again and it worked fine, then I measured voltages of the pins and I got the following values: Vs = 2VDC, 3V3 = 3.3VDC, VIN = 5VDC, Ve = 0 VDC, as you can see the only voltage value that changed was that of Vs (down 3 VDC) and I’m concerned about the fact that the indicator LED of the LoRa module is not working. I would like to know what may be happening, since the day before everything worked very well, , and how can I solve it.
Thanks for your help. I wait fast answer.
