- You Reply: I also tried the Bluno Link (TEL0087). I think it would allow entry into the Beetle’s “AT” commands if it didn’t use the same “AT” entry command as the Beetle, “+++”.

Are the pins in this picture labeled correctly?
Bob - You Reply: Grey,
Thank you!
The sketch works for me on a DFR0351 board. So my problem is in my firmware.
Bob - You Reply: I am doing a “smart”-model-train-locomotive. The original Bluetooth-board I was using allowed the main-processor to control it. Just wondering if I will be able to access and control other model-train Bluetooth-controlled-items (such as turnouts) using the Beetle-board in my “smart”-locomotive. This allows the “smart”-locomotive firmware to be upgraded so that it can operate autonomously without a separate Bluetooth-train-layout-controller.
Thank You!
Bob - You Reply: The problem is my “?good deal?” Android tablet! I should not have assumed that it had bluetooth 4.x just because it had android 4.x.x. Thank you for your help and patients with my lack of bluetooth knowledge!!!
Bob - You Reply: Tried these steps. Still no connection between the DFR0351 board and the “Bluno Basic Demo” App.

Bob - You Reply: I do not have the DFR0351 connected by USB and it is powered by a separate ~7 Volt supply.
The wiki page “Romeo BLE mini SKU:DFR0351” gives a link in the wiki page “Bluno SKU:DFR0267” for “How to update the BLE firmware”. This page gives a link in “Download and decompression the Firmware in the Document section ( This is the Link )” that downloads the “BLE_FW_1.8e_14-05-13” BLE F/W. But this does not appear to be the latest version.
The latest version appears to be 1.97 found here “https://github.com/DFRobot/BLE_firmware_V1.9”.
So far I have tried both BLE F/W versions and cannot get a connection between the DFR0351 board and the “Bluno Basic Demo” App on an Android 4.4.2 tablet. (This tablet is able to connect to a Bluetooth speaker OK.)
Is there a latter or better version to try than 1.8 or 1.97?
Thank you!
Bob - You Reply: The BLE adapter-tel0087 worked; thank you!
However, my initial effort to wirelessly connect and control the DRF0351 board from an android-tablet based on “Bluno Basic Demo” was not successful. The Apps Bluetooth-Scan did not find the DRF0351 board. Do I need to use the BLE adapter-tel0087 on the android-tablet or a different DRF0351 BLE firmware, or ?
Thank You!
