i've already done the sudo chmod 755 xxx.sh with file. Is there a way to double check it does have permission? i have also done the reboot after everything you suggest but the x708 does not shut of...

Hi, This is the EMC brought by USB 3, you can refer to https://raspberrypiwiki.com/images/5/53/Usb3-frequency-interference-papers.pdf; Normally, 5G AP can be connected. Try to cover the copper f...

Hi I got my X728 board and have a question I would like to power on the board using an external signal (from an other system). Is any pin out (switch) on the X728 able to start this power-on on d...

Hello   X828 attached to Pi 3, powered by X710. works. HDD works fine   but none USB 3 port works with Flash dongle or 3G dongle when plugged in X828 (LSUSB does not detect anything)....

@Harry Huang  I was not talking  about external switch but the PCB switch . it simply does not work   Tx

As the title says when using my Raspberry Pi 4 with X857, X872 and X735 the Wi-Fi doesn't connect to anything, I tried both 2.4 and 5 GHz, they are detected correctly but it just doesn't connect. ...

@james mutch  My script posted yesterday should turn the pi AND the x708 off. Hence something else is amiss. The rc.local file should only contain: /home/pi/shutdown.sh echo ds1307 0x68 &g...

Hi, I've installed the script and hashtagged all the lines that were in rc.local apart from the last 3. It looks like the shutdown part works after 30 seconds when i pull the power adapter out but...

Thought i would ask another question regarding bluetooth...i seem to be having difficulty connecting to a bluetooth keyboard. The only way i can get it to connect is to have the keyboard directly a...

so the text line that contains echo ds1307 0x68 > /sys/class/i2c-adapter/i2c-1/new_devicehwclock -s i need to put a hashtag infront of all of these? Any idea what these are? I recently install...

Hi James Regarding the rc.local file: As you can see, the same lines are repeated over and over again. I would place a '#' in front to make them comments. The only lines you need are the last thr...

here is my code for rc.local #!/bin/sh -e## rc.local## This script is executed at the end of each multiuser runlevel.# Make sure that the script will "exit 0" on success or any other# value on err...

Hi George, I did everything you said in the post but for some reason when i run the test and pull the power plug when the pi logo shows it shows a black/blank screen for about 30+ seconds and boot...

@james mutch  Hi James I have managed to cobble together yet another script that has now solved all my problems. This may not work for you, James, but I am posting this for everyone needing...

Hi, 'AUTO ON' mean the x710 will AUTO POWR ON when the AC main power supply is connected, so the external switch is disable when 'AUTO ON'

@Mark Muti  Yes. liPo battery is ok also.

@james mutch  Hi,  I test my method, and It should be effective. . . You can also connect a 20-30 ohm resistor to the red wire in series with the 2P wire of the fan to reduce the voltage.

Apollogies for constant replies as i can't seem to amend my post above to add stuff :/  Anyways... when you said that it has shutdown and won't get a response from command line does this mean...

George.... how long a runtime are you getting with just 2 batteries connected? What is the average time of 2 x 2000mah batteries on this setup running before shutdown?
