MySensors Arduino Nano FTDI on Rpi3-Problem Topic is solved

[piokuc]

Hi
I have a problem. I create on Arduino nano V3 on chipset FTDI Mysensors Gateway. I connect it do my New Raspberry Pi3. It is show ok on USB1:

Code: Select all

pi@Domoticz:~$ dmesg | grep attached
[    4.297950] usb 1-1.5: ch341-uart converter now attached to ttyUSB0
[  135.134804] usb 1-1.2: FTDI USB Serial Device converter now attached to ttyUSB1
pi@Domoticz:~$

But after reboot Raspberry it is not find and reconized:

Code: Select all

pi@Domoticz:~$ dmesg | grep attached
[    4.297950] usb 1-1.5: ch341-uart converter now attached to ttyUSB0
pi@Domoticz:~$

When i unplug and plug again to RPI3 it is start now again show ok.But after restart again not find.

I also has Arduino Nano v3 on chipset CH340. Also create MySesnors Gateway and this modul still is correct show on RPI3 also after reboot. Why on chipset FTDI is problem ?
Please help me.

My setup works fine
I use RPI3 ver B 1.2,
4.4.26-v7+ #915 SMP Thu Oct 20 17:08:44 BST 2016 armv7l GNU/Linux

Code: Select all

dmesg | grep attached
[   14.308087] usb 1-1.4: cp210x converter now attached to ttyUSB1
[   14.310129] usb 1-1.3: ch341-uart converter now attached to ttyUSB0
[1361554.169128] usb 1-1.3: ch341-uart converter now attached to ttyUSB0

I just wonder which type serial gateway Arduino you are using since mine is ch341 and your show up as FTDI?

My
[ 4.297950] usb 1-1.5: ch341-uart converter now attached to ttyUSB0

is from RFLink on Arduino Mega (clone)

But MySensors i have on Arduino Nano v3 (clone) buying on Aliexpress, And this Arduino Nano is in FTDI. I also test Arduino Nano v3 also buying on aliexpress and it was on chipset CH340(showing as CH341). But on this MySensors crashes when recived first signal from my node. And then i have problem on RPI3. Ihave RPI3:
Linux 4.4.38-v7+ armv7l GNU/Linux

Installed from sd image and then upraded. Anybody can help me with problem gateway on FTDI and CH340 ?

Why on chipset FTDI is problem ?

May be not too late.
Solution:

In short: it's a hardware bug on the nano V3 boards (may be some other...). Pin 26 of FTDI should be connected to ground, but it's not.
Solution is solder blob between pins 25 and 26.

For me it work.
