For Pockethernet 2 firmware, please check for an update in the app.

[Changelog]
v34:
New features:
- Add support for the v2 wiremap adapter for spare part availability

V33:

New features:
- Report: The reporting has been completely reworked
   - Multiple reports can be combined on one page and reports can have multiple pages
   - There are fewer user/address fields, but a new one has been added: Tag. This servers as a short description of the test which will also be included in the filename
   - You can add a custom logo to the report in the Settings menu. This image file can then also include your name and address next to the logo.
     The suggested image is a PNG of 1181x236 pixels which corresponds to a 5x1cm rectangle @ 600dpi. The file needs to be on the phone to be selected.
- Displays Voice VLAN ID via CDP
- Android 9+ compatibility upgrades (runtime permissions, fileprovider for file sharing, gallery access, wakelock)
- Added LLDP-MED parsing: LLDP-MED capabilities, Network policy, Extended power via MDI and Inventory information are displayed
- MAC address change: You can now change the MAC address of the device in the settings menu to allow testing DHCP allocation and 802.1X MAB
- Separated CDP and LLDP measurements to show them both on networks with mixed equipment
- External IP detection support
   - You can now query the external IP address of your link and get the IP, the ISP and AS name and corresponding GeoIP data.
- Auto-ping: If all 3 ping targets are empty, and a ping test is requested, the targets are automatically set to the ip of the dhcp server, gateway and dns server

Updates (feature changes):
- The Power LED behaviour has changed. It now goes from white: fully charged, to yellow: charge OK to red: recharge needed
- To make them more obvious, the measurement selection icons are now bigger and high-contrast
- Remove Wiremap per-pair status display, add shield as separate black pair for better overview
  The per-pair status created more confusion than use since it cannot be determined per-pair if they fit overall configuration
- Make help screens bigger
- TDR distance per pair is added to the report
- Ping reports now only error or reply received
- Display Graphical TDR results in meters/feet according to settigns
- Adjust graphics for devices with bigger fonts in accessibility settings
- Keeps screen on while measurement is running
- Updated help texts
- Wiremap shorts are now drawn in order and over the wires
- Custom MAC: the masked MAC input field didn't work with alternative keyboards so it's now a simple input that accepts an : or - delimited address

Fixes:
- BER fix
- DHCP requests didn't work on 10/100 links with some switches, updated request timing to fix it
- CDP: Management address wasn't correctly displayed in CDPv2 packets
- Ping server names are correctly added to the report
- Fix toner pair numbering and add wire colors for easy selection
- Adjust tabs by some pixel to always have rounded corners at the bottom
- Make all long texts scrollable in measurement results
- The VLAN tag field could become ineditable
- In some cases multiple ping targets didn't work
