Using a chinese ModBus temperature sensor

I’m testing this modbus SHT20 temperature and humidity sensor: https://www.aliexpress.com/item/SHT20-Temperature-Humidity-Sensor-Industrial-Grade-High-Precision-Temperature-Humidity-Transmitter-Monitoring-Sensor-Modbus-RS48/32923628973.html

There is not much information about this device at Aliexpress. Fortunately searching for the string XY-MD01 that was in the board returned this Russian web site: http://www.bizkit.ru/2018/11/14/5789/

It give a little more detail about the device. Also I found other website that used a different temperature sensor, but the modbus address and protocol is almost the same: https://techsparx.com/energy-system/modbus/linux-modbus-usb-rs485.html

The sample application worked correctly. All I did was to change the modbus_get_response_timeout() to include “&old_response_to_sec, &old_response_to_usec” as it was in the comments and changed the temperature division to: “(tab_rp_bits[0] / 10.0)”.

After some tests I got mbpoll working to read data as well:

$ sudo mbpoll -a 1 -b 9600 -r 2 -t 3 -P none /dev/ttyUSB0

It is nice as the Internet save our soul! I hope this post eventually help other people as well.

How to make VirtualBox to recognized USB Devices

By default VirtualBox on Ubuntu will not detect the USB Device. In order to get it working you need to install the Oracle Extended Package and add add your user to vboxusers group.

You can do it running these two commands:

$ sudo apt install virtualbox-ext-pack
$ sudo usermod -a -G vboxusers $USER

After doing it, please restart your computer (just doing logoff worked for me).

ImageMagick not authorized error

I was getting this error:

$ convert -density 150×150 +antialias -negate FILE1.PDF F1.png
convert-im6.q16: not authorized FILE1.PDF’ @ error/constitute.c/ReadImage/412. convert-im6.q16: no images defined F1.png’ @ error/convert.c/ConvertImageCommand/3258.

I found the solution here: https://stackoverflow.com/questions/52861946/imagemagick-not-authorized-to-convert-pdf-to-an-image/52863413#52863413

Accessing Internet from NuttX PPP Connection

As you know I was facing some issues to get PPPD connection working:

https://acassis.wordpress.com/2019/02/10/debugging-pppd-using-quectel-m95-on-samd21-board/

Then I received a comment from Vladimir Novikov (thank you!) at that post commenting the issues was introduced some time ago at this commit:

https://bitbucket.org/nuttx/apps/commits/cddfda99f0a519681b894b7a12560406c4372cfb

And he suggested me adding this line to lcp.c:

          tptr = bptr;
+          bptr += 4;
          error = 0;

Before testing this suggestion I received an email from Quectel Brasil support (thanks Micael Lisboa) suggesting run this AT cmd:

AT+QACCM=0,0

Micael’s suggestion worked fine.

But I decided to contact the author of the modification (Xiao Xiang) and he explained that the bptr was already increased by 4 compared to original code. And in fact he was correct.

Anyway I decided to test Vladimir’s suggestion that also worked. So we need to investigate it in more details to understand what is happening.

BTW since the AT command was working for me I decided to follow with my tests.

After PPPD connection was established it was getting IP:

nsh> ifconfig
ppp0    Link encap:TUN at UP
        inet addr:100.75.210.38 DRaddr:192.168.254.254 Mask:0.0.0.0

But ping command was crashing:

nsh> ping 8.8.8.8

After much debugging and with Greg’s help I noticed the “srcipaddr” was not aligned:

(gdb)
194       net_ipv4addr_hdrcopy(ipv4->srcipaddr, &dev->d_ipaddr);
(gdb) p &ipv4->srcipaddr
$1 = (uint16_t (*)[2]) 0x20000c41 
(gdb) p &dev->d_ipaddr
$2 = (in_addr_t *) 0x20000eac 

See, it was at 0x20000c41 that is an odd address position.

Almost instantly Greg found the source of this issue: it was the TUN/TAP driver that was defining the read_buf at odd position:

 142   bool              read_wait;
 143
 144   uint8_t           read_buf[CONFIG_NET_TUN_PKTSIZE];
 145   size_t            read_d_len;
 146   uint8_t           write_buf[CONFIG_NET_TUN_PKTSIZE];

Moving the “size_t read_d_len;” to the line above read_buf[] fixed the issue!

Now ping is not crashing and I was able to ping the Google’s DNS 8.8.8.8:

nsh> ping 8.8.8.8

How to use git behind proxy

I was willing to use git behind company proxy.

Then I found these tips:

https://stackoverflow.com/questions/2088156/git-through-digest-proxy-authentication

Unfortunately just adding it didn’t work:

git config --global http.proxy "http://USERNAME:PASSWORD@IP:PORT"
git config --global https.proxy "https://USERNAME:PASSWORD@IP:PORT"

Searching a little bit more I found the final piece:

https://askubuntu.com/questions/1061945/not-able-to-connect-to-github-via-proxy

git config --global http.proxyAuthMethod 'basic'
