Idea for this PR is to add a network bridge mode for repeaters.

This will let you take multiple LoRa radios, setup meshcore repeater firmware and listen on any number of channels or with different antenna setups and bridge the routing across those different channels with a shared Wifi link(the two dotted white boxes).

I've tested it for a few days and it's pretty amazing to see meshcore automatically finding bridged routes.

Complex repeater topology. Typical user companion radios are shown as circles. Repeaters are shown as diamonds. The colors of the nodes indicate their frequency.

@s1r83r If you're just getting started, strong recommend to start with the RAK WisBlock hardware (or really anything with the nRF chipset) because the battery life is exponentially better than the #esp32 based options.

That said, the T-Deck plus looks sexy and I'm always tempted.

ESPShell (0.99.7) for esp32 by Viacheslav Logunov

➡️ github.com/vvb333007/espshell

This library adds a command line interface (CLI) to your sketch. CLI can be used for development or debugging, with all commands built-in: provides access to I2C, UART, filesystem, GPIO's etc

woah, exactly as theorised by literally everyone that isn't fucking racist: #ESP32 "#backdoor" was just sensationalised by a security firm in order to get clicks for their own blog post which is basically just advertising their services

big conflict of interest. who knew that the biggest security violation will always be capitalist motives ✨

Does anyone happen to know if the #ESP32 modules ESP32-C3-MINI-1U-N4X or ESP32-C3-MINI-1U-H4X are available?

It is a ESP32-C3 miniature module that I want to use in a prototype. It seems like a perfect fit, but their own documentation says to not use the ones I can actually purchase.

I don't mind buying it, I just can't find a distributor and asking them for a distributor or sample involves filling out a 20 page form with personal information that they don't need.

Un grupo de investigadores ha descubierto un agujero de seguridad en el popular microcontrolador ESP32 cuyo uso está ampliamente extendido en el ámbito del IoT. Lo que han encontrado es una serie de comandos ocultos en la controladora de Bluetooth destinados a la depuración, pero que se pueden usar para infectar el dispositivo #esp32 -> hardlimit.com/archivo.php?n=22

So, let's try to improve the #Esp32 range with an external antenna.
I scraped the #wifi #antenna contacts and cut the trace going to the rest of the internal antenna. Then soldered the cable with the #sma connector savaged from the #fonera . The shielding of the cable goes to GND (used the multimeter to find which one is GND) and the inner to the other antenna contact.

3️⃣ Für einen kurzen Moment sah es so aus, als ob die Geschichte der Killer-Zahnbürsten nun doch Realität geworden ist: Auf allen einschlägigen Tech-Portalen machte am Wochenende die Geschichte einer Backdoor im #ESP32-Microchip die Runde. Spanische Forscher hatten diese an einer Konferenz in Madrid vorgestellt. Dieser Chip ist weltweit milliardenfach in IoT-Geräte verbaut, eine von aussen angreifbare Lücke wäre definitiv gefährlich. Aber es ist nur normales Debugging…
