Re: receive keystrokes from a usb keyboard

| Note: Remember that the ATmega runs on 5V, and therefore it reads 5V as logical high.

I use a classic NFC reader PNR532 V3 (like: https://images.app.goo.gl/uouKyD4WnnLDmuhHA) - SPI connection.

I used a lots of that reader connected directly on 5V of the omega PINOUT (expansion header) with ARDUINO DOCK 2 with onion board.

Now I bought 100 new NFC reader and if I connect them on an ARDUINO UNO everything work very good, but if I use the Onion Power on the ARDUINO DOCK 2 (5V) they don't work fine.

I noticed two thing:

1. with the 3,3V of the expansion header the new readers works good
2. these new reader are more powerfull, the reading range is wider.

Is the 5V power of the ARDUINO DOCK different from the real Arduino UNO?

many many thanks!!!

@György-Farkas said in Wifi LAN Active - how to know:

You can change the priority with the wifisetup priority -ssid <ssid> -move <up|down|top> command.

Thank-you very much

I noticed the section config wifi-iface 'sta', bu when I use the command line
wifisetup add -ssid $SSID -encr $ENC -password $PasskeyWifi

is there the possibility to force then specific $SSID?

config wifi-iface 'sta'
option device 'radio0'
option mode 'sta'
option ifname 'apcli0'
option encryption 'psk2'
option network 'wwan'
option disabled '0'
option key 'mywifi'
option ssid 'xxxx'

Is there the possibility to know which wifi LAN the OMEGA2 is using?

or a specific information to read in some file like?
vi /etc/config/wireless

Thank-you!!

Tank-you @Douglas-Kryder do you know the right package repos I have to insert into the file:

/etc/opkg/distfeeds.conf

Because if I try the command:
opkg install ipset

Response:
opkg_install_cmd: Cannot install package ipset.

Thanks in advance.

Hi,
I tried to connect my omega2 with this guide https://onion.io/2bt-using-hologram-expansion/.

I'm using ArduinoDock. When I tried to restart the firewall with
/etc/init.d/firewall restart

I received an error

Warning: Unable to locate ipset utility, disabling ipset support
Warning: Section @zone[2] (cellular) cannot resolve device of network 'hologram'
Warning: Section @zone[2] (cellular) has no device, network, subnet or extra options

• Flushing IPv4 filter table
  ...

Is there an alternative guide? or Where is the problem?

Thank-you.

Paolo
