This CC3000 module from Texas Instrument is obsolete. The new module is the CC3200.
I'm looking for other possibilities.

brump: "I had an idea of using a wireless (WiFi) gateway for nodes with RFM69HW radios"
papa: Sounds like a good option. brump & others, let us know if you make progress (ideas or actual) on this.
Via internet search, I saw some Arduino WiFi shields using ESP8266. Would one of those be good enough?

Via internet search, I saw some Arduino WiFi shields using ESP8266. Would one of those be good enough? I have searched in many forums, and there is not enough return to use this shield. In Knolleary Github I did not find success. I've seen some open tickets for this problem solution in using a wifi shell and MQTT. |

Yes, brump, I've done some research also. Some challenges to overcome if using ESP8266 WiFi: ESP8266 can only run & communicate at 3.3 volts, but also requires more current power than an Arduino can supply. So ESP8266 probably needs a dedicated power supply. ESP8266 may need to communicate with an Arduino Mega which has more than one dedicated serial communication pins. (Software Serial emulation cannot handle enough communication for this.) I experimented with connecting an ESP-01 module with a Buono Uno. That worked a little, but not very well. This video explored four options to adding WiFi to an Arduino, three that failed, & one that succeeded (Arduino WiFi Microcontroller at 19 minutes & 21 seconds). However, the successful item was not available at www.robotshop.com. This search at www.robot.com offered some other options, some of which claimed to provide enough current power for the ESP8266. I'm not sure how much I will pursue this. A wired Ethernet RFM69 Gateway works well for me. |

Papa,
I watched the video. I had seen this pcb, just don't remember the store.
I found a viable solution using the module atwinc1500 of Atmel sold by approximately US$9,00.
The shield for the Arduino is marketed by adafruit in two options: with antenna at the PCB or external antenna.
The library for the module is the wifi101.
I understand that for many, the Ethernet network meets well, but I'm looking for another option for the Gateway making viable a freedom highest to your positioning.

brump, congratulations on finding a WiFi module that seems promising for our gateway. I will post here if I choose to try that module, but it will be at least two weeks before I am able.
Keep us posted on your results with this module.

brump: I found a viable solution using the module atwinc1500 of Atmel sold by approximately US$9,00. papa: Yes, as here, I saw the separate atwinc1500 module at various costs starting at $9+ US before shipping, etc. brump: "The shield for the Arduino is marketed by adafruit in two options: with antenna at the PCB or external antenna." papa: Yes, as here, Adafruit has the atwinc1500 unit mounted on a shield for about $25 US before shipping, etc. brump: The library for the module is the wifi101. papa: Yes, looks like one can use Arduino IDE to program the module on the shield. Here, Adafruit provides more info on understanding & using the shield. papa: This documentation page makes me wonder if the atwinc1500 shield might conflict with some pins (CLK MISO MOSI) that the RFM69 radio uses at D11, D12, D13, but it looks like the rest of the Arduino pins needed could be manageable. |

Papa, These pins are from the SPI interface, so all devices can be connected in parallel. Only the CS pin that needs to be in an available digital pin. I am awaiting the arrival of the module to carry out the tests. |

Thanks, brump, for answering that concern. Best wishes on receiving the unit & making a working WiFi gateway. Keep us posted on your results.

Here's a good explanation of SPI: LINK |
