Cudy: set up your PisoWiFi

WR1300 V3 · Cudy's own OpenWrt first, then AJKFi. Two files, both in the Cudy WR1300 V3 Drive folder.

Firmware 3.84.1 · coin slot 2.9 · guide of 2026-10-29 · Negros Oriental, Philippines

1. Flash AJKFi

Cudy's own OpenWrt first, then AJKFi. Two files, both in the Cudy WR1300 V3 Drive folder.

1. Check the label
   Turn the router over. The label must say V3 (for example V3.0). These files are for the V3 only - other versions have different parts inside.
2. Flash Cudy's OpenWrt
   Network cable from your PC to a LAN socket. Open the Cudy settings page (http://192.168.10.1, or the address on the label) and sign in. Open the firmware upgrade page, choose the Cudy OpenWrt file, and upload it. Do not unplug anything while it writes.
3. Flash AJKFi
   When it restarts, open http://192.168.1.1 (OpenWrt). Go to System → Backup / Flash Firmware → Flash new firmware image. Choose the AJKFi file, untick Keep settings, and flash. The router comes back on http://10.0.0.1:8080.

2. Activate

1. Plug in the internet
   Put your internet cable into the router's WAN socket. The router needs to reach us once to collect its licence.
2. Open the admin page
   Connect to the Wi-Fi called AJK PISOWIFI, then open http://10.0.0.1:8080. Sign in with admin / admin.
3. Activate
   Open System. If you sent us your Account ID when you bought, press Check In Now and the licence arrives by itself. If you were given a licence code, type it in instead. The page shows Licensed when it is done.

3. Set the admin password

1. Change admin / admin
   Go to Settings → Admin Account and set your own password. Anyone connected to your Wi-Fi can reach this login page, so do it before the machine goes out.
2. Put the dashboard on your phone
   Open http://10.0.0.1:8080 on your phone. Android (Chrome): menu ⋮ → Add to Home screen. iPhone (Safari): Share → Add to Home Screen. It gets the AJKFi icon and opens straight to the Dashboard.
3. Open it from anywhere (Cloud Remote)
   Sign in at ajkfi.com, open My machines and press Remote - the dashboard opens already signed in, from anywhere with internet (AJKFi 3.55 or newer, Lite 1.4 or newer). Give the machine a name there with Rename. Remote can be switched off on the router under Network → Cloud Remote.

4. Name your Wi-Fi

1. Name your customer Wi-Fi
   Network → Wireless. Rename AJK PISOWIFI to your shop name. Leave it open - customers pay at the portal, not with a password. Name it before you open: the name cannot be changed while a customer with running time is connected.
2. Add a hidden Wi-Fi for the coin slot
   On the same page, under Add Another SSID, add a second SSID on the 2.4 GHz radio, tick Hidden, and give it a password - required, the coin slot will not join a Wi-Fi without one. 2.4 GHz matters: the coin slot board cannot see 5 GHz.

5. Connect the coin slot

1. Flash the board
   Easiest: open ajkfi.com/flash (the ESP8266 Online Flasher) in Chrome or Edge on a computer, plug the board in with a USB data cable and press Connect and flash - choose New board for a new one, Update for one already in service (it stays paired with the router). Or use PyFlasher or NodeMCU Flasher: 115200, DIO, erase yes on a new board, no when updating. From coin slot 2.5 on, later updates come from the router: Settings → Coinslot Hardware → Update coin slot.
2. Pair it with the router
   On the router tap Pair coin slot in Settings → Coinslot Hardware, then power the board. A coin slot 2.9 or newer finds the router by itself: within about a minute the router shows Paired - no phone, nothing to type. Then set the lock to Active HIGH in Settings → Coinslot Hardware → Coin acceptor wiring and tap Save to coin slot. Older board, or two machines pairing at the same time: join the board's own Wi-Fi AJKFi-Coinslot-Setup from a phone, pick the coin slot Wi-Fi, type its password, set the lock mode to Active HIGH and press Save & connect.
3. Wire it
   Three wires from the coin acceptor to the ESP8266 board: COIN to D6, SET (the lock wire) to D7, and GND to GND. The ground wire is not optional - without it the coin slot counts coins that were never inserted. The 12 V adapter runs the acceptor and the board together through the base board's DC socket.

   

4. Test it and put it in the box
   Insert a real coin through the portal and watch it appear. Then drop a coin without tapping INSERT COIN: it must come back out - if it is taken, switch the lock the other way in Settings → Coinslot Hardware → Coin acceptor wiring on the router and tap Save to coin slot (coin slot 2.4 + AJKFi 3.45 or newer; older boards: on the board's setup page, hold its FLASH button 3 seconds). If coins go in but no time is credited, try the coin signal (D6) setting there the other way. The wires do not change. Then mount everything in the box and test one more coin. Swapping in a new board later: tap Pair new coin slot in Settings → Coinslot Hardware first.

6. If the router will not start

1. Give it time
   The first start after a flash takes a few minutes. Leave it powered for 5 minutes before you decide it is stuck.
2. Ask us before trying anything else
   Message us on Facebook with a photo of the label and what the lights are doing. Do not flash another file on top - a second wrong file is what turns a fixable router into a repair job.
