Rockey 200 Driver Gsm-forum May 2026
| Symptom | Likely cause | Solution |
|---------|--------------|----------|
| No response to AT | Wrong baud / power / serial polarity | Try 115200→9600→4800; check TX/RX swap |
| +CME ERROR: 2 | SIM not inserted or PIN locked | Insert SIM, send AT+CPIN=1234 |
| +CMS ERROR: 500 | SMS storage full | Delete old messages: AT+CMGD=1,4 |
| Modem resets on GSM TX | Power supply too weak | Add 1000–2200µF capacitor or use 2A+ PSU |
| No network (+CREG: 0,2 or 0,3) | Antenna missing or wrong band | Attach GSM antenna (SMA or IPEX) |
| USB not recognized | Driver missing / fake chip | Use older driver (Zadig / manual .inf) |
| Step | Command | Note |
|------|---------|------|
| APN | AT+CSTT="internet","user","pass" | Use your carrier APN |
| Bring up | AT+CIICR | Wait 5–10 sec |
| Get IP | AT+CIFSR | Should return e.g., 10.xxx.xxx.xxx |
Test HTTP GET (with SIM800 firmware):
AT+HTTPINIT
AT+HTTPPARA="URL","http://httpbin.org/ip"
AT+HTTPACTION=0
AT+HTTPREAD

The Rockey 200 is a 2nd generation USB dongle. Unlike standard HID devices, it requires a proprietary kernel-mode driver (Rockey200.sys) to communicate via custom control transfers. This paper documents the driver's IOCTL (Input/Output Control) structure and the hashing algorithm used for authentication, as reverse-engineered by the GSM-Forum community.
Device: Rockey 200 (SIMCom SIM800H or similar core – check your version) Type: Industrial GSM/GPRS modem, USB / RS232 (DB9) / TTL Purpose: SMS, voice, GPRS data, IoT, alerting systems
The legitimate driver creates a device object \\.\Rockey200 and responds to the following critical IOCTL codes:
| IOCTL Code | Function | Purpose |
| :--- | :--- | :--- |
| 0x22A004 | Find | Searches for connected dongles. |
| 0x22A008 | Login | Sends hashed seed to verify dongle. |
| 0x22A00C | Read | Reads from protected EEPROM (cells 0-127). |
| 0x22A010 | Write | Writes to EEPROM (requires password). |
| 0x22A018 | Convert | Runs the internal hashing algorithm (CRC/MD5 variant). | rockey 200 driver gsm-forum

When dealing with drivers and software modifications, especially those involving flashing or unlocking devices, it's crucial to:
The Rockey 200 driver is primarily used as a stable solution for advanced SIM and smart card readers, particularly for users of "Powerdongles" and similar hardware on the GSM-Forum. It is often recommended to resolve recognition issues where Windows fails to detect a dongle after removal. Technical Features & Specifications According to documentation from Java Card Forum Rockey 200 hardware and driver support several key standards:
Host Interface: USB 2.0 (backwards compatible with USB 1.1).
Protocols: Supports ISO7816 T=0 and T=1 communication protocols. | Symptom | Likely cause | Solution |
Standards Compliance: Fully compliant with ISO/IEC 7816 parts 1, 2, 3, and 4. Performance: Clock Frequency: Ranges from 4MHz to 12MHz. Interface Speed: 9600bps up to 625kbps. Card Compatibility: Supports Class A, B, and C smart cards. GSM-Forum User Consensus
OS Compatibility: Users have confirmed it works perfectly on Windows 7 64-bit and is expected to function on 32-bit systems.
Versatility: It is noted for working with a wide range of dongles without fault, making it a reliable alternative to standard drivers that may be buggy or require frequent re-installation.
Troubleshooting: Experts on the forum emphasize using original drivers rather than "hacked" versions to avoid card detection errors like "Card not found".
