Configure irobot wifi series using command line
I finally got there!
- Reset to robot (press Clean until all lights up)
- Start Soft AP (press Home+Spot) until sound + green wifi led blink - Eventually try again if the error bip sounds
- The password is pushed to the robot using an MQTT Authentication Exchange packet
echo -n "f023efcc3b29003a313a313537393139353338363a386678376e597156744b67574a39744f" | xxd -r -p | openssl s_client -CAfile robot-ca.pem -connect 192.168.10.1 -quiet -noservername. This output the password back if set correctly.
packet format:
| Value | Description |
|---|---|
0xf0 |
MQTT Authentication Exchange packet fixed header |
0x23 |
The size of the remaining Bytes after this (35 in decimal) |
0xefcc3b2900 |
Voodoo packet 😸 |
:1:1579195386:8fx7nYqVtKgWJ9tO |
Format: :1:timestamp:16 alpha-decimal chars |
Note: I have not played using different password format, so use with caution.
Connect using mqtt protocol v3.1.1 and send commands via json messages from the table bellow on the right topic and disconnect after. (I use only 6, 9, 10, 11, 12, it seems to be sufficient for a basic configuration). Having a little pause between commands seems to help the process a bit. Once sent, the SoftAP should turn off and the wifi led should turn fixed white.

| 1 | delta | { "state" : { "timezone" : "Europe/Paris" } } | makes the robot bip once of two |
| 2 | wifictl | { "state" : { "sdiscUrl" : "https://disc-prod.iot.irobotapi.com/v1/robot/discover?robot_id=0000000000000000&country_code=FR&sku=R966040" } } | I did not checked what is this api… |
| 3 | wifictl | { "state" : { "ntphosts" : "0.irobot.pool.ntp.org 1.irobot.pool.ntp.org 2.irobot.pool.ntp.org 3.irobot.pool.ntp.org" } } | |
| 4 | delta | { "state" : {"country" : "FR"} } | |
| 5 | delta | { "state" : { "cloudEnv" : "prod" } } | |
| 6 | wifictl | {"state": {"wlcfg": {"pass": "wifisecretpasssword", "sec": 7, "ssid": "575757"}}} | pass as clear text, ssid as octal (mine is WWW here), sec??? |
| 7 | wifictl | { "state" : { "utctime" : 1579291795 } } | timestamp |
| 8 | wifictl | { "state" : { "localtimeoffset" : 60 } } | |
| 9 | wifictl | { "state" : { "chkssid" : true } } | |
| 10 | wifictl | { "state" : { "wactivate" : true } } | |
| 11 | wifictl | { "state" : { "get" : "netinfo" } } | |
| 12 | wifictl | { "state" : { "uap" : false } } |
There is a proof of concept in this repo.
-
press the 'CLEAN' button until you hear a sound, keep it pressed, it will blink, keep it pressed, all light flash, now release
-
press home + spot until you hear a melody
-
connect you PC to the Access Point. Roomba will speak
-
Check the WIFI SSID name, it's your BLID, set it in the script
-
Update your wifi parameters in the script
-
Launch the script
Note: the instruction that set "timezone" must emit a bip.

A bash script has been added with the mqtt commannds. It require mosquitto client ($ apt-get install mosquitto-clients).
Do not forget to edit the script to set your values.
I want to thanks my wife and my familly ;)
