BT26E01 FAQ

Hi Eletechsup team,

 We are developing an ESP32-based controller for caravans, vans and boats and are looking for a very small BLE-controlled inline 12V DC load switch.

We found your BT26E01 and its published AT+O1 / AT+C1 commands. Can you supply an existing enclosed inline version, or adapt your existing BLE design into a fully assembled four-wire product?

The customer must connect only four wires:
12V INPUT + and − → enclosed switch → LOAD OUTPUT + and −.

The Bluetooth electronics must be powered internally from the incoming 12V supply and remain available when the load is switched off. No separate power leads, external jumpers, relay socket or exposed PCB.
BLE control directly from our ESP32, without your phone app, Wi-Fi, internet or a proprietary gateway. Please provide the service/characteristic UUIDs, ON/OFF commands and pairing/authentication details.
At least 10A continuous DC is our target; 15-30A would be preferable if practical within the size. Please state the actual continuous rating, ambient-temperature limits, motor-start/inrush capability and any required protection—not just the relay component's maximum rating.
Loads include 12V water pumps, lights, fans and Starlink Mini power. We need direct load switching, preferably MOSFET/solid-state; a properly DC-rated mechanical relay is acceptable. Electronic accessories require a steady ON/OFF mode, without dimming/PWM.
Internal antenna only. Enclosed body ideally smaller than 70 × 40 × 25mm, preferably waterproof or automotive-style. Please state dimensions, operating voltage range, switching technology and actual IP rating.
To minimise development cost, our preference is to adapt an existing design and enclosure rather than commission a completely new product.

Could you please confirm:

Whether you can supply this finished product, with photos/drawing and wiring details.
Price and lead time for one fully assembled evaluation sample, including shipping to Australia.
Minimum order quantity and indicative unit prices at 10, 50 and 100 units, with any engineering/tooling costs listed separately. These quantities are for quotation only.
Availability of BLE documentation or an ESP32 control example, standby current, and behaviour after power loss or Bluetooth disconnection.
Any existing Australian RCM compliance documentation, radio/EMC test reports or other relevant certification for the proposed finished model.
Please identify any requirement you cannot meet. We would evaluate a sample before deciding on a production order.

 yes, Eletechsup can OEM ODM for you  ; 

Thanks for your reply. Could you supply the BT26E01 fitted inside a small enclosure and fully prewired, ideally using the existing electronics and firmware?

We want a ready-to-connect unit with only four external wires: two for the 12V supply (+/−) and two for the load (+/−). All internal connections should be completed by you, with no exposed board, separate power leads or jumper wires for the customer to add.

Would you be open to supplying 100 units like this, or a smaller initial quantity? Does the 1,000-unit minimum also apply to enclosure and wiring assembly alone?

Please let me know the minimum quantity, price and lead time for this assembled version, and whether we could purchase one finished sample first.
