Can't connect to my LoPy4 board
-
@robert-hh tanks for the flags, appreciate it! sorry, takes me a while to find a multimeter. if i'm right the red cable go to the tx pin and the black to gnd, i can see 3.3 - 3.4 V
-
@Liudmila-Dobriakova Responding should now be faster. I gave you a few + flags.
-
@Liudmila-Dobriakova The bridge is OK and the Putty setting is correct.
Then there is trouble with the LoPy4 board. Which is strange, because they are quite robust usually. If you have a voltmeter, can to measure the levekl at the bridge TX output when nothing is connected?
-
@robert-hh as a new user i can reply only every 10 min, sorry fot the delay... no lights on board
-
@robert-hh the second test for USB/UART bridge, i hope i get it in correct way. i've connected the pins as on foto and opening PuTTY can see all characters digied from the keyboard on the terminal. so looks like the bridge is OK, right?
-
@Liudmila-Dobriakova What is the result of the loopback test?
Another question: Is the blueheartbeat flash going on at the LoPy4?
-
@robert-hh i've tried to connect via Putty with the standard settings u suggested, but looks like putty is not connecting too. i get this screen stacked and nothing happening if i push the reset button as well.
-
@robert-hh i'll try all what u suggest and let u know. Thank u for the suggestions so far.

@Liudmila-Dobriakova Please try to conect trough a simple robust terminal emulator program like putty, to sort out any issue with Atom and PyMakr.
For Putty, you have to set the speed to 115200, 8, N, 1, and flow control off.
Putty should at least connect, even if the LoPy does not respond. After connection, push the reset button of the LoPy4 and tell, what you get.If you cannot connect with Putty, the USB/UART bridge might be broken.
You can test that one with a loopback test. Disconnect the LoPy4 and connect TX and RX of the adapter. Then every typed character should be echoed.

@robert-hh no other components are connected, only LoRaWAN antenna. It is heating in general, it is pretty small so it's hard to define if the heating of specific component is happened.
-
@Liudmila-Dobriakova That wiring look OK. Board getting hot is not a good sign. Is it a specific component that gets hot?
-
@robert-hh it is powered by converter via USB port, TX is connected to TX, RX-RX, GND - GND and the +5V to VIN
-
@Liudmila-Dobriakova How do you power the board?
