UPDATE: Support for Chameleon connections using Bluetooth BLE is under active development

[maxieds]

Recent releases of this application (CMLD) have fixed Android permissions errors for the optional configuration option to enable Bluetooth (BT) connections (checkbox under the Settings > General tab). I am working towards getting the BT connections for the Proxgrind RevG / Tiny / TinyPro Chameleon devices. I will be testing this code soon and hope to rollout a new release that adds BT support soon (fingers crossed).

In the meantime, I would like to gather some information from helpful users. If you use the Chameleon Mini over a Bluetooth connection, can you please report any alternate names/aliases (things that your device is called by the BT stack on your system of choice)? I have observed the following three so far. Newer releases of the onboard BT firmware may have changed things since the last time I looked at this:

• BLE-Chameleon
• Chameleon
• ChameleonTiny

Note that this project to get BLE/Bluetooth Chameleon device connections working is still in progress. More commits with progress and further testing towards this goal will be posted soon. Keep an eye on the most recent pre-releases for signed beta testing APKs before this functionality is pushed to Google Play Store. Beta testers are very much appreciated!

Oh, hello there!

I just had issues connecting my rev.G mini via BLE and was about to ask you about troubleshooting - but luckily I decided to look here into the issues first.

Well... suppose I'm a beta tester now 😅
I'm running emsec firmware. If I were to switch to the rrg firmware, I could connect and use their app just fine, so Bluetooth itself works.

About the Bluetooth firmware upgrade that is mentioned in your in-app troubleshooting steps: Is it the thing where you in proxgrind app tap something like "BLE CMD version" like 4 times and a "secret" update dialog comes up? Or is it something else you were mentioning?

If you need me to try something specific, I'd be happy to assist - I already have to thank you for tirelessly implementing the desfire emulation! Now that I think about it, I may actually even owe you 😁

Have a nice day~!

I accidently get my chameleon mini's bluetooth firmware lost, any chance I can get a firmware to flash in?

It may be the case that the RFID group's interface is described here. I will not be supporting this app for a while.

I have a feeling that the reason BT support with the Chameleon Tiny devices (Bluetooth-enabled) did not work with the app was that on top of getting a BT connection to the device with Android, you have to put the Chameleon (connected over BT) into an under-documented command mode. For example, see the UART files (x4) here and the command codes in this header. I did manage to get this output testing several years ago.

If anyone wants me to continue working on BT support, please email me (maxieds@gmail.com)(mailto:maxieds@gmail.com) if you can donate a Chameleon Tiny or other BT-enabled Chameleon device.
