  Finally found a solution: If you use your own custom webserver to setup the omega and want to display nearby Networks. <?php echo shell_exec("ubus call onion wifi-scan \"{'device':'ra0'}\""); ?> ^ This DOESN'T work! because: the php-interpreter doesn't have enaught ram to excute the command. It'll take a eternity. Solution: in /etc/php.ini set memory_limit form 8M to 32M memory_limit = 32M ; Maximum amount of memory a script may consume. now the scan only takes about 5sec.

  @Manny-Rodriguez We've actually written about using MQTT on the Omega. Check out the MQTT heading in the tip index at https://onion.io/2-bullet-tuesday/

  @Jon-Gordon Learning first hand from rm mistakes is usually best done early in one's *nix adventure. Glad you got it sorted.

  @Marti-MG I hope I'm not too late. If you want to use GPIO18 (PWM_CH0) only then you should remove U6 the 6 pin SOT23 marking C145 SMD IC only. See also the official Omega-Power-Dock schematic. After this modification Power Dock 1 remains fully functioning. You can check the battery level visually with the pover-dock command as before - but the 'battery level check' scripts will not work of course. Power Dock Checking the Battery Level

  Thanks for the detailed reply. I went with option 3 and managed to fit some 0805 onto the 0603 pads and it works as expected. Thanks again.

  @Zheng-Han This morning I turned on my Omega, entered ping repo.onion.io and then opkg uptate. Update did not happen, I was upset and turned off Omega. Now I turned on Omega and it successfully booted without errors, and the update was also performed. I hope that my problem has finally been resolved. But if she comes back, I will return to you. Thank you for your help.

  Had a new one though....I have python 2 and 3 installed on the Omega. Though, I can't get the python 3 script to use the pyserial module. It keeps giving me a 'module not found' error. Should I uninstall Python 2 and try to reinstall pyserial?

  Similar module LinkIt Smart 7688 seems to have it... Hello Onion staff, full audio support could be a smashing freature for a small form factor module, but missing nice features like camera port etc.

  You can't. But you can try USB to Ethernet adaptors they may work.

  Yes about sign : drivers which were used as bases of our omega simpleaudio driver seemed S16 as normal but if Andrew is sure it actually sends unsigned then that is the problem : If the maxxxxxx driver actually uses the unsigned (weird unstandart and rare) 16bit format then we need to switch our firmware to builds using an asoc/alsa wm8960 or pcm5102 or whatever else is available as nearly ALL OTHER i2s drivers would provide us the usual/standart (i2s meaning signed) our DAC chips need. "MCK lack" subject is not the problem here because I also use a i2s DAC chip that features an MCK generation builtin because MT7688 chip does not have any MCKout. These 2 matter would make me much regret the former ar9331 soc chip...
