Open Source Software OpenMQTTGateway got initial support for Open Source Hardware ESP32-GATEWAY

OpenMQTTGateway project aims to concentrate in one Gateway different technologies like Bluetooth, LoRa, IR, lagacy RF 433/315, GSM/GPRS based devices and connect them with OpenHAB, Home Assistant, Jeedom, FHEM, Domotic etc platforms via MQTT protocol.

The list of the supported devices is long.

With recent PR initial support for ESP32-GATEWAY is add.

ESP32-WROOM-32 WiFi/Bluetooth module is in stock!

ESP32-WROOM-32 modules are in stock now!

Again these are from the very first lot and with limited supply. To give chances to more developers to try them we will not allow more than 3 modules per order.

This module is good only if you develop your own board. For these who are not good with the soldering iron and SMD components soldering our advice is to wait for new supply of ESP32-CoreBoards or our own ESP32-EVB which will come with two Relays, Two buttons, SD-card connector, Ethernet 100Mbit and all signals on prototyping friendly 0.1″ step connectors.

Thanks for all who posted tips on our blog about ESP32-EVB feature wishlist!

EDIT: there was question on Twitter if these are original Espressif parts and why there is no FCC/CE markinig, my guess is that the certification is not complete, as it’s in the datasheet but not on module body. The modules come directly from Espressif, as you can see from reel label they are manufactured October 15th 2016 and one week later are in our stock for sale 🙂

ESP32-CoreBoard is sold out, ESP32-EVB design has started

ESP32 is really hot, the first lot we got sold out for couple of days. If we didn’t put the restriction for one module per order it would be sold out in matter of hours, as people wanted to buy x5 and x10.

ESP32-WROOM-32 modules are shipped from Espressif and we wait them to arrive next week.

Meantime we started the design of our ESP32-EVB board.

What we think so far is to have these features:

• power supply from 5V
• LiPo charger and step up converter to allow un-interruptable power supply
• Two relays 220VAC/15A
• Two user buttons
• UEXT connector to which you can connect many of our sensor UEXT boards, or to program the board with serial cable same way like ESP8266-EVB
• status LEDs

With the two relays you will be able to switch on and off two different appliances.

With the sensors on UEXT you will be able to measure temperature, light, moisture etc. and log them.

The plan is to complete the design in October and start selling this board in November.

Our target is to release this EVB for EUR 15.00.

If you think we should add something else let us know.

New product: The popular HC06 Bluetooth to Serial modules are now in stock

HC06 are popular Bluetooth to Serial modules bases at CSR BC04 Bluetooth technology. They have with build-in 2.4GHz antenna, support Bluetooth class 2 power level and operate with voltage in range 3.1V~4.2V

If you want to add Bluetooth wireless connectivity to your next device without hassle with Bluetooth protocol, HC06 will allow you this working as simple as with UART. The module have AT commands to listen and pair to other nearby BT devices, then you exchange data like if you worked with wired uart.

Tons of Arduino examples are available on the net. The module is made to be easy soldered on your own custom board.

Blueooth and Internet of things. Whaaat?

When I hear this for the very first time, I though OK these guys just have no clue, but this term comes again and again.

Yesterday Cypress had seminar about their PSoC BLE solutions which I participated and again I heard Internet of Things dozen of times.

C’mon guys how do you connect BLE sensor or device to Internet? -> With computer/gateway connected to Internet.

Then I can connect any sensor with USB or UART to computer and again make it visible to Internet, but I do not call any devices with USB or UART IoT devices!

If one device have no Ethernet or WiFi how does it connect to Internet???

BLE is good, it’s low power 2 to 5 meter wireless device which could even make mesh and this way to extend the range or wireless connectivity, but this is not Internet! So please stop this marketing buzz!

(BLE != IoT) period
