Kaleido HiBean BLE Firmware
SnowBear Firmware Installation
Kaleido currently uses Classic Bluetooth to talk to HiBean  a dated standard that, importantly, isn't supported on iOS at all. This project is a workaround that finally brings Kaleido connectivity to iPhones and iPads. It also pairs nicely with Bear's bridge for connecting devices over BLE Serial, which sidesteps the long-standing issues Classic Bluetooth SPP has on macOS, especially on Apple Silicon. Brought to you by Bear of the Skywalker community, with support from Will_Z at HiBean. 
Machines Confirmed Kaleido Roasters that work:
M1 Lite
M1 Pro
M2 LEGACY (Unsealed)
Requirements
This is still in Beta and code is still being worked on. Please report any issues you have to our Community Discord.
ESP32-S3:
 Ensure you have the ESP32-S3 board 
USB A Male to USB C Male Cable (UART)
or

ESPHome
Steps
1. Download the Binary File
Open the GitHub link
Click on the download raw file icon to download 
2. Open ESPHome Web
Go to 
ESPHome Web
 in your Chrome or Edge browser.
Make sure your ESP32-S3 is connected to your computer using a USB cable.
3. Connect the ESP32-S3
On the ESPHome Web page, click the Connect button.
A pop-up will appear with available devices. Select the port for your ESP32-S3 and click Connect.
4. Install the Binary File
Once connected, click Install.
Choose File when prompted
In the file selection dialog, locate and select the BLE_host_v1.2z_Kaleido_SnowBear.bin bin file you downloaded earlier.
Click Install to start the flashing process.
5. Flash the Firmware
ESPHome Web will erase the existing firmware and flash the BLE_host_v1.2z_Kaleido_SnowBear.bin  binary.
The flashing process may take a few minutes. Wait for it to complete.
After successful installation, a success message will appear.
6. Plug into Kaleido Tablet USB Port. (Top USB port not the bottom)
Direct Link to Binary File
Troubleshooting
Device Not Recognized: Ensure your USB cable supports data transfer.
Flashing Errors
Hold BOOT and press RESET (recommended method):
Hold down the BOOT button.
While holding BOOT, press and release the RESET button.
Continue holding BOOT for a second, then release it.
Unplug and replug while holding the BOOT button:
Disconnect the ESP32-S3 from power (USB).
Press and hold the BOOT button.
While holding BOOT, plug the USB back in.
Once connected, release the BOOT button.
Let me know if you encounter issues or need further help!
Not all wires are the same ensure your wire has Data Wires not a 2 strand charging wire.
BIG Thank you to Bear of the Skywalker Community Discord and Will_Z for getting this option to work.

Kaliedo Protocol
Kaliedo Roaster Protocol
Quick command reference for Artisan / HiBean serial control
Format Conventions
Instruction stream uses {[ as prefix and ]} as suffix.
Data stream uses { as prefix and } as suffix. Responses start with sid (status byte).
All keywords are uppercase. Each command is terminated with a newline (\n).
Multiple commands can share one {[ ]} pair, separated by commas — for example: {[HP 80,FC 60,RC 90]}
Connection and Setup
Command
Description
{[PI]}
Ping — connection test. Returns {sid}.
{[SC AR]}
Start Artisan session. Returns {sid,SN:xxxxxxxx}.
{[SC CP]}
Start Cropster session. Returns {sid,SN:xxxxxxxx}.
{[CL AR]}
Close Artisan session.
{[CL CP]}
Close Cropster session.
{[TU C]}
Set temperature unit to Celsius.
{[TU F]}
Set temperature unit to Fahrenheit.
Reading Data
Command
Description
{[RD A0]}
Read main parameters (BT, ET, AT, HP, FC, RC, AH, TS).
{[RD A1]}
Read main parameters plus heating status (adds HS field).
Example response (A1)
{0,BT:190.5,ET:185.0,AT:25.0,HP:80,FC:55,RC:90,AH:0,TS:180.0,HS:1}
Response fields
BT — bean temperature (0-300 °C / 32-572 °F)
ET — drum / environment temperature
AT — ambient temperature
HP — heater power %, step 5
FC — smoke fan speed %, step 5
RC — drum roll speed %, step 10
AH — auto-heat enabled (0 or 1)
TS — target temperature setpoint
HS — heating active (0 or 1, A1 mode only)
Heat Control
Command
Description
{[HS 0]}
Stop heating.
{[HS 1]}
Start heating.
{[HP n]}
Set heater power n% (step 5, range 0-100).
{[HP UP]}
Step heater up by 5%.
{[HP DW]}
Step heater down by 5%.
{[TS n.n]}
Set target temperature (0-250 °C / 32-482 °F).
{[AH 0]}
Disable auto-heat (manual power mode).
{[AH 1]}
Enable auto-heat (device PID controls heat to TS).
Fan and Drum
Command
Description
{[FC n]}
Smoke fan n% (step 5, range 0-100).
{[FC UP]}
Step fan up by 5%.
{[FC DW]}
Step fan down by 5%.
{[RC n]}
Drum roll n% (step 10, range 0-100).
{[RC UP]}

{[RC DW]}
Step drum down by 10%.
Cooling
Command
Description
{[CS 0]}

Roast Event Markers
Sends a user-tagged roast event to the device. The device synchronizes the event to its embedded control panel.
Command

Dry End — end of drying phase.
{[EV 4]}

Status Byte (sid) Decoder
Every response begins with a status byte. Convert sid to 8-bit binary, then read the low 4 bits when the lowest bit of the high nibble is 0:
Command
Description
0000
IDLE
0001
CHARGE
0010
TP (Turning Point)
0011
DRY END
0100

Typical Session Sequence
The handshake Artisan uses on connection, captured live from a real roaster:
Command
Description
{[PI]}
Ping the roaster to verify connection.
{[TU C]}
Set the unit (C or F).
{[SC AR]}
Open an Artisan session — roaster returns its serial number.
{[RD A0]}
Poll for live data, repeated about every 1.5 seconds.
{[CL AR]}
Close the session when disconnecting.
Notes
Polling interval for RD should be at least 1 second. Default 1.5 seconds. Repeated queries faster than 1 second are ignored.
The roaster responds to RD without requiring SC AR first, though using SC AR is the documented startup sequence.
Baud rate observed: 57600, 8 data bits, no parity, 1 stop bit, no flow control.
CP210x VID:PID is 10C4:EA60.
