 +====== Ubiquiti Airmax M ======
 +
 +The Ubiquiti Airmax M series are based on ar71xx chipset. They include:
 +
 +^  Airmax M series  ^^
 +| NanoStation M       | sectorial 60 deg antenna, high power, 2 ethernet      |
 +| NanoStation Loco M  | low cost sectorial 60 deg antenna, 1 ethernet         |
 +| PicoStation M HP    | omni directional, high power, 1 ethernet              |
 +| Bullet M            | other form, high power, 1 ethernet                    |
 +| Rocket M            | high end, usb                                         |
 +| PowerBridge M       | Rocket M with high power antenna, 1 ethernet          |
 +| NanoBridge M        | device-in-feeder directional dish antenna, 1 ethernet |
 +
 +**Note:** For the models with 1x ethernet (nanostation loco m, picostation m hp, bullet m), use the bullet-m image.
 +
 +The bullet-m image is the base of the airmax series.
 +
 +The rocket-m image is the bullet-m with an additionnal usb driver. As of 22.03 there is no dedicated Rocket-M ath79 image use the Bullet-M AR724**0** image
 +
 +The nano-m image is the bullet-m with an additionnal ethernet.
 +
 +The NanoBridge-m works fine with bullet-m r30919
 +
 +**Special Firmware Note:** AirOS XM.v5.5.X images used U-Boot 1.1.4.2-s594 (Dec  5 2012 - 15:23:07).  The OpenWRT image can be successfully flashed onto these versions of firmware.  However, in July 2015 Ubiquiti released a new version of firmware XM.v5.6.X.  With this firmware a new U-Boot version was released,  U-Boot 1.1.4.2-s956 (Jun 10 2015 - 10:54:50).  The newer U-Boot version changes the memory size and starting address for rootfs, cfg, and EEPROM.  LOADING AN OPENWRT IMAGE ON A U-Boot 1.1.4.2-s956 WILL CAUSE THE DEVICE TO BE BRICKED!!! 
 +
 +If the device has XM.v5.6.X, an older version of XM firmware can be loaded from the AirOS webgui (for example XM.v5.5.10) and U-Boot will be overwritten with the older version.  OpenWRT can then be loaded onto the device successfully.

 +===== U-boot Versions =====
 +
 +Hashes of various u-boot's published by Ubiquiti are documented here: [[:toh:ubiquiti:ubiquiti-uboot]]
 +
 +
 +===== TFTP flash =====
 +
 +Power cycle the device while you keep the reset button pushed. Leds will start to blink red and yellow.
 +
 +Then tftp the image to 192.168.1.20 following the instructions at the [[docs:guide-user:installation:generic.flashing.tftp#bootloader_contains_tftp_server|Installing OpenWrt via TFTP]] page.
 +
 +===== Remote reset =====
 +It is possible to remotely press the reset button on M-series devices by briding the powerlines, Ubiquiti's 1 ampere power injector (the one with LAN LEDs) has a button that you can press that physically closes the reset button circuit. If you have the smaller power injector or a generic one, you can read http://dren.dk/mreset.html for more information about making your own reset button out of it.
 +
 +===== Serial =====
 +
 +Serial pins are clearly labeled. GND, SOU, SIN, PWR (3.3V). the PWR connection is not needed when plugged in.
 +
 +Serial settings (which also works for other Ubiquiti M devices):
 +
 +''Bits per second : 115200
 +Data bits       : 8
 +Stop bits       : 1
 +Parity          : None
 +Flow control    : None''
 +

 +
 +==== Other models ====
 +
 +There are also the Unifi and Litestation X which are in the same ar71xx family, but they have different init in the openwrt source.
 +There are 4 models of the Unifi, Unifi AP, Unifi AP LR (Long Range), Unifi Ap PRO, Unifi AP Outdoor
 +
 +The PowerBridge M, NanoBridge M, AirGrid M are in the airmax M family, but not tested?
