**** BEGIN LOGGING AT Mon May 10 02:59:56 2021 May 10 12:33:50 beaglebone black can handle multiple input at time from multiple IO pins May 10 12:54:20 Hello, is there someone who knows how to make a power button on BBB a wakeup source from sleep state (echo mem > /sys/power/state) May 10 14:43:28 beaglebone black can handle multiple input at time from multiple IO pins May 10 14:47:02 beaglebone black can handle multiple input at time from multiple IO pins May 10 15:19:52 RajMehta[m]: is that a question? if so, what do you mean? May 10 18:50:34 I have a BBBW.  If it's plugged into my PC I can enable wifi and it works fine.  If I power it via a phone charge bank, Wifi works for maybe 20 minutes then just dies....Kinda confused May 10 18:52:49 ok...nevermind...I just don't have wifi at all even with usb...So wi-fi is being lost 15-20 minutes after enabling wifi... May 10 18:53:16 do you mean wifi in client mode or the access point? May 10 18:54:11 um I don't know what that means May 10 18:54:35 as in, are you connecting the bbbw to a wifi network, or are you connecting to the wifi network created by the bbbw ? May 10 18:54:56 the network created by the bbbw.  connected right now via putty May 10 18:55:44 on both usb or the wifi network I can't ping anything now.  I could like 10 minutes ago May 10 18:56:21 usb down too? has the whole beaglebone crashed or is the usr0 led still blinking in a heartbeat-pattern ? May 10 18:58:39 I am still logged in now via putty and can issue commands.  I have 1 led going in a heatbeat with another occasionally blinking May 10 18:59:21 if you're still logged in then you can also ping it, unless you're just doing something wrong (or windows firewall is being dumb or whatever) May 10 18:59:45 usb has an ip address but keeps saying there was a temporary failure in name resolution May 10 19:00:20 I can ping the BBBW just fine May 10 19:00:46 having working name resolution requires that the beaglebone has internet connection, which generally requires that you connect it to an existing wifi network May 10 19:01:37 like I said it was all working just fine then suddenly stopped in the middle of a package download May 10 19:01:52 so you *are* using it in client mode then? May 10 19:01:52 now I can't get internet if I am connected via usb OR the wifi network May 10 19:02:10 I'm a bit confused as to what your setup is, you're giving conflicting information May 10 19:02:10 I have tried both May 10 19:02:26 I am connecting in client mode right now May 10 19:02:52 giving the bbb internet access via usb, while possible, is generally quite tricky and prone to lose connectivity entirely May 10 19:03:18 ok....but like I said it lost wi-fi suddenly and without error or warning May 10 19:03:28 I'd generally recommend it not be attempted unless you really know what you're doing May 10 19:03:39 hmm that's odd, you'd expect it to at least reconnect May 10 19:03:52 I know May 10 19:04:03 hence my confusion and frustration right now May 10 19:04:30 I have a bbbw that's been running for 293 days and while it occasionally loses connection it always reconnects May 10 19:04:40 thanks that helps a ton.... May 10 19:05:34 wait May 10 19:06:07 why is usb "hard to do" but it's exactly what is recommended in the documents?  They tell you to plug the BBBW into a pc May 10 19:06:20 sharing internet to the bbb via usb is hard to do May 10 19:07:04 since it requires reconfiguring network settings on both the pc side and the beaglebone side in a way that risks losing usb network connection entirely May 10 19:07:28 ok....fair enough May 10 19:07:35 the recommended thing is just connecting to the bbb via usb, that's not a problem May 10 19:07:39 (but that won't let you install packages) May 10 19:08:58 This is the moist infuriating piece of hardware I have ever tried to use May 10 19:09:35 I'm sorry to hear that... I'll admit I normally use ethernet-connected beaglebones, not wifi-connected May 10 19:10:56 though like I said, the bbbw here seems to have pretty stable wifi, it disconnected only a few times the past month (and each time reconnected) May 10 19:11:19 I wonder if the access point that's enabled by default is causing problems May 10 19:11:36 you could try disabling that to see if that makes the client connection more stable May 10 19:12:11 I think that's TETHER_ENABLED=no in /etc/default/bb-wl18xx May 10 19:12:44 well I have wifi connect right now and can ping google May 10 19:14:16 but I shouldn't have to repeat those steps every time... May 10 19:14:23 which steps? May 10 19:14:28 auto connect is enabled May 10 19:14:57 connmanctl May 10 19:15:34 I don't use connman really, but yeah that would be my assumption too May 10 19:15:52 (I replaced it by systemd-networkd on all our beaglebones) May 10 19:17:09 I was just trying to get this going....I don't get what the heck is happening May 10 19:17:59 anything useful in journal? (journalctl) May 10 19:33:06 sorry was waiting for a package....I am not sure what "interesting" means May 10 19:33:41 timer_probe: no matching timers is in red... May 10 19:35:08 yeah no, I mean stuff about it disconnecting from wifi May 10 19:35:32 (someone should really fix some of those bogus "errors" that show up during early boot that don't actually mean anything) May 10 19:35:52 failed to set domainname to home May 10 19:37:05 you can use "journalctl | pastebinit" to create a paste of the entire log May 10 19:38:21 ok May 10 19:41:53 that's not working it returns a url of paste.debian.net ....wifi seems to still be stable though May 10 19:42:27 that *is* working if it returned a url May 10 19:42:59 if you share the url here I can take a look at the log May 10 19:43:14 sure.... paste.debian.net May 10 19:43:25 wait it didn't have anything after the / ? May 10 19:43:35 yes....exactly May 10 19:43:39 huh May 10 19:44:07 I... have no idea what these mysterious problems are you have May 10 19:44:27 should I just nuke the install and start over? May 10 19:44:55 that sounds like overkill unless you think you specifically did something to hose your system May 10 19:45:17 ....I barely know about what you are talking about....How would even know if I hosed my system.... May 10 19:46:39 all I know is wifi is working now.  Maybe it was coincidence or something.... May 10 19:47:14 do you see any reason why I couldn't use a phone power bank to power the BBBW? May 10 19:47:21 the wifi chip realized you were getting help so it quickly started to act nice? ;) May 10 19:47:59 you should be able to use any 5V source that can supply enough current (2A recommended though you may be able to get away with less than that depending on use case) May 10 19:49:03 that's kind of what I thought May 10 19:50:06 maybe its voltage sags too much under load or something like that, dunno... hard to say without hooking up a scope or something May 10 19:54:26 grr the connection is super slow on the battery charger.  Sigh I just wanted a portable system May 10 19:54:48 that's weird, I don't see how the power source could affect the wifi connectivity May 10 19:55:06 I am connected via putty and typing takes for ever to complete May 10 19:55:55 oh, just to confirm, have you rotated the antennae so they're sticking out? ( https://photos.app.goo.gl/tgXV8iQo3SQCrmdG8 ) ... since they're rotated inward just for shipping May 10 20:00:43 I didn't know that was a thing... May 10 20:02:51 jkridner: maybe that should be mentioned in the getting-started guide, that if you have one of the wireless beaglebones with discrete antennae that these should be rotated outward? May 10 20:03:35 it may have been but wasn't prominant.  That fixed the issue so far with the typing. May 10 20:06:49 e May 10 20:08:03 thank you for the help so far. May 10 20:08:10 np May 10 20:25:09 zmatt: maybe. would certainly help reception. I worry a bit about people rotating them incorrectly, but it really is necessary. May 10 20:25:47 yeah they're kinda annoying to rotate.. I wonder if it wouldn't be better to just include the antennae separately in a little bag May 10 20:26:01 zmatt: do you have a best place to put the note? May 10 20:26:15 attaching the antenna can be equally painful as rotating. May 10 20:26:16 ¯\_(ツ)_/¯ May 10 20:26:29 ok, I was just wondering about that May 10 20:31:11 anyone know if the heat pipes on the BeagleV are required? May 10 20:51:00 ds2: I don't run one with mine. I monitor the temperature every now and again. If I don't want to check, I just use a "Argon Fan Hat" May 10 20:51:25 The non-beta will have a different temp profile. May 11 00:03:41 if I want to power the BBB by the pins rather than barrel jack or usb do I need to change any settings May 11 00:03:50 or does it autodetect the power source May 11 00:04:16 also if I have a 5V5A step down source will that fry the bone? May 11 00:10:40 mattb000ne: Barrel jack is physically connected to the power inputpins, so there isn't any difference between the two May 11 00:12:29 thanks outrageus and it is the VDD pins right not sys May 11 00:12:32 ? May 11 00:13:58 Yes, P9_5 amd P9_6 May 11 00:16:27 VDD_5V that is, are P9_5 amd P9_6. GND is P9_1 and P9_2 May 11 01:23:57 jkridner: the heat pipe makes the expansion port useless May 11 01:43:21 jkridner: do you know if they glued the pipe on? May 11 01:44:21 I don’t. Best to ask pdp7 on Slack May 11 01:49:22 jkridner: do you still do campus visits to talk about beaglebone May 11 01:49:43 i see some old videos of you on youtube wondering if you still do that or someone else does May 11 01:49:51 noy since covid May 11 01:50:17 hypothetically what does it take to book you May 11 01:50:37 i really, really need to make new videos, but haven’t managed to feel properly motivated. May 11 01:50:47 We have a growing maker space at UNC chapel hill May 11 01:50:51 would be a good venue May 11 01:51:22 just invite me and get an audience. i don’t collect speaking fees like Massimo Banzi. ;-) May 11 01:51:52 ok May 11 01:52:05 just email the generic info May 11 01:52:12 I will shoot something to the director May 11 01:52:15 ds2: I have an adapter board that I can ship you. Please email drew@beagleboard.org May 11 01:52:17 for something in the fall May 11 01:52:18 I have come out to UNC before. May 11 01:52:28 cool May 11 01:52:54 we have new makerspace director and we have changed a lot May 11 01:52:59 not sure when your last visit was May 11 01:54:30 Couple years. There is a TI university guy close. Mark Easley May 11 02:10:22 ok I will talk to the powers that be and get back to you May 11 02:10:31 we have a lot of people interested May 11 02:11:09 i cannot get power to the bone via barrel jack May 11 02:11:17 usb port works though May 11 02:11:20 hmmm **** ENDING LOGGING AT Tue May 11 02:59:57 2021
