Aug 08 11:53:08 i want to convert RSSI to distance ..i gone through some formulas but not getting accurate values.could anyone please help me Aug 08 11:56:43 doesnt that vary by antenna in use, existing noise in the spectrum etc ? Aug 08 11:57:17 * ogra_ doubts you can compute that accurately just by RSSI Aug 08 11:57:36 yes its varying Aug 08 11:58:19 i am using "hcitool rssi " to get the RSSI Aug 08 11:59:09 after that i am repalcing in the formula RSSI=-(10*n logd-A) Aug 08 12:00:19 but not getting correct answer Aug 08 12:12:26 jagadeesh: RSSI is goign to fluctuate like crazy unless you are in a pristine RF environment.. it's be near impossible to use that for distance in an accurate way Aug 08 12:13:26 unless you had multiple recievers in multiple locations and could use triangulation and averaging to clean up the error margins Aug 08 12:13:30 ..also many devices change their transmit power Aug 08 12:24:00 ok thank u@freemor Aug 08 13:52:48 hello. Why today my BBB wants to flash instead of booting from SD as it has do for months? Aug 08 13:53:36 there was a partital moon eclipse last night ... Aug 08 13:54:52 at boot it starts the "cylon" led pattern for a while and then end with all 4 leds flashing. If i put an older SD with an older Debian image it boots from SD without problems. Aug 08 13:56:16 I don't know what cause the "usual" SD not booting. About the eclipse, i know, but the office is oriented in the opposite way, should'nt have been a problem. Aug 08 13:58:53 ah, yeah, then you should be fine :) Aug 08 14:02:39 serioulsy, guys, i'd really apreciate some help. Aug 08 14:06:42 Parduz: not sure why the behavior would be different with the different cards but I've seen the button get flaky before. Maybe check that it's reading correctly Aug 08 14:10:22 thanks georgem, but i repeated the "test" more than 4 times. The old SD boots, the "current" one not anymore. Tryed to read it (using Linux Reader as i am on Win7) and the partition is there and seems readable Aug 08 14:10:44 I meant: the button seems working good. Aug 08 14:12:10 Parduz: fire up some linux and check the bad card for fs defects, etc. Aug 08 14:13:03 Parduz: Okay. TBH I barely remember how that flashing process works. I've been using only my own images for several years now which don't have that. I do recall once having a strange problem with it reflashing only to find with a multimeter that the button was registering as closed and only after fiddling with it for a bit did it go back to the open state. Aug 08 15:35:22 BBB: my SD does not boot anymore... instead the BBB starts trying flashing.is it normal not having a uEnv.txt in the SD card i'd like to Aug 08 15:35:30 boot from? Aug 08 15:36:07 isnt there a button you can hold at boot to select boot from uSD? Aug 08 15:39:01 I have a "current" SD which ceased to boot today. An older one with a older image boots. Aug 08 15:39:51 mount the sd on a pc, salvage what you need, create a new sd on pc, then boot away? Aug 08 15:40:08 whatever i try to do (boot button, reset, power cycle) the old one works, the current one no more. Aug 08 15:40:22 What I'm trying is to find the problem before (or without) loosing a day reinstalling everything Aug 08 15:41:04 problem is the amount uf stuffs i've to apt-get and compile. Aug 08 18:42:29 Is there a beaglebone that can operate from -40C to 85C? Aug 08 18:43:09 ur lucky if it works but i think its not its official rating abean Aug 08 18:44:43 there is a abbbi which has this rating Aug 08 18:45:02 https://www.arrow.com/en/products/bb-bblk-000-itemp/arrow-development-tools Aug 08 18:46:05 if you need volume, you can get a quote for a re-design with proper ratings etc Aug 08 23:05:35 grrrr.... the scum recruiters are multipling Aug 08 23:06:29 ds2: this room needs more ops ;) Aug 08 23:06:43 possibly tangential, but hey :D Aug 08 23:07:50 that helps Aug 08 23:08:09 someone ought to spoof resumes back to thse spamming recruiters Aug 08 23:09:12 veremit: Hey, you ALREADY have ops in a channel, don't be greedy. Aug 08 23:22:01 wait what.. *checks* .. no . *all the things* majuk :P **** ENDING LOGGING AT Wed Aug 09 02:59:59 2017
