As an access point - not working well

Greetings, I've configured my Pi to act as an access point. DHCP, routing, hostapd, etc. At first glace this seems to work great. I can use my phone to connect, browse, etc. But after a period of time the wireless client stops working. Pings from pi -> client fail. Client can no longer access the in...

hostapd not running properly at boot

Greetings, I've set up hostapd, and when running from the command line it works correctly (runs, loads config, and I can connect). However, when the pi boots, hostpad gives a non-descript error in syslog. It does run, but it doesn't broadcast an SSID. Jan 31 10:45:00 raspberrypi hostapd[519]: Starti...

Re: Raspberry Pi 3 BT audio issue

I couldn't use the pi3 for BT audio. There are no SCO packets passed during the phone call. It's either a limitation of the hardware or the driver. I couldn't get any further and I ended up using a USB dongle.

RPI3 - undervoltage

I've been using a 5v supply, rated at 2.1A. Once in a while I get the undervoltage image, but not 100% of the time.
I replaced this with a 5v 2.5A power supply, and now I get the undervolate image 100% of the time.

Should I assume this is a junk power supply?

Re: BT Pairing - Python Code

Okay, I didn't realize this could be a function of the dongle. Mine is a CSR. I'll turn on debugging and check it out.
I can live with the passkey, but I would prefer the PIN. Thanks for your help!

Re: BT Pairing - Python Code

Thanks for that. You're right. I was hurried and working with this neglected to really pin point what "doesn't work" means. With the capability change, there was definitely a positive result. Previously, when specifying a PIN in the agent, it was seemingly ignored. The phone would pair, but it would...

Re: Raspberry Pi 3 BT audio issue

I'm running the latest version of Bluez, actually. I am going to email their list and see if I can get deeper.
Reason: Remote User Terminated Connection
This is what happens when you disconnect the call. So, it's a normal message!
