Re: pi 3b cant connect to a hidden ssid network

In your wpa_supplicant.conf file, do you have

Code: Select all

scan_ssid=1
in your network block?

Re: wpa_supplicant.conf

Resolved. My final result was this, with appropriate redaction: network={ ssid="MY_SSID" scan_ssid=1 proto=RSN pairwise=CCMP key_mgmt=WPA-EAP auth_alg=OPEN eap=PEAP identity="MY_ID" password=hash:MY_HASH phase1="peaplabel=0" phase2="auth=MSCHAPV2" } Hope this helps anyone else with a similar issue.

Re: Pi3 does not see built-in WiFi

A happy ending for me :) I received an email that the nice folk at Pimoroni are sending me a replacement. We couldn't pin down which order it was, so potentially it is out of warranty, but typically for them, they are replacing it. Including this, I have had three issues relating to purchases from t...

Re: wpa_supplicant.conf

Typical. I ask for help from a literally world-wide community, and get help from someone who lives within a 15 mile radius :)
The second thread contains much information that is useful, and when the relevant Pi is in the right place to try, I will certainly be doing this.

Thanks

Hi. Yes, I'm in the UK. However, I cannot remember when I bought it, although it was probably from Pimoroni, as I buy nearly all my Pi stuff from them.

Re: Pi3 does not see built-in WiFi

OK, I have now tried a different Pi3 with the same PSU and SD card. It is quite happy, seeing both Bluetooth and WiFi. Similarly, none of the available SD cards in the problematic Pi3 make any difference. Logically, it must be hardware. As it is some time since I bought this particular Pi3, any chan...

Hi I have a Pi which connects at different times, to two unconnected AD systems. The first is at home, the second at work.

Re: Something new

While you (and many others) have a good use-case for this, it is not generally applicable to all RPi models. Redesigning the PCBs to fit this chip isn't simply a case of finding space. You also have to route power, ground and IIC signals. Why push up the price point for hardware that isn't going to ...

At the risk of doing a "Me too" post, that is pretty much how I get connected. Indeed, I take it a step further. When I download a new image of Raspbian (on a Pi, of course!), I then run a script which mounts the /boot partition from the image, and creates two files in the partition's mount point. T...

You could use the BASS music library. http://www.un4seen.com/bass.html . This is a fully featured playback system that is relatively straightforward to use, and can play MP3 and OGG files. Make sure you get the Pi ARM version though, not the x86/x64 ones. I use all three, so I can test on a PC, then...

Re: [pigpio] Bad I2C Bus

I don't disagree that i2c bus#0 is there, but I wouldn't use it. It is used by the video core, (aka the GPU), for things like the camera. You almost certainly want to follow the good advice of changing to i2c bus#1 instead. It will save you lots of headaches in the long run.

Re: PCA9685 board with RPi 3 problems

How are you powering the servo motors? I never power anything from the Pi if it is at all avoidable (which it mostly is), unless I'm using a HAT or pHAT which is designed to do that, such as the Blinkt (from Pimoroni). When driving servos, I always power them from a separate supply, connecting the P...

Re: PCA9685 board with RPi 3 problems

Well, the fact it has detected something at 0x40 matches the default address for the PCA9685.
If you run servo.py, do you get any output?
Looking at the code in GitHub, it should print some sort of informational messages about the pi module/revision, and so on.
