Re: [IoT] ESP Product Selector IoT Espressif
My colleagues are interested in RISC-V. Unfortunately, the product selector doesn't appear to let you filter for the CPU type (Xtensa or RISC-V). Could that please be added to the product selector? We're also interested in integrated Ethernet MAC. So far, that's only on the ESP32 classic (says the p...

Re: ethernet: need to configure two PHYs over internal MAC, but send no data
We're talking about SMI here. That's for control, getting/setting registers in the PHYs. It's not for sending data. If you want to send data, you'd want to use the regular Ethernet stack, which sends data to and from the PHY via some MII. PHYs can talk about 2.5 MBit/s or even 25 Mbit/s on SMI. With...

Re: LLVM for Xtensa
You know what would thrill me? Running a Julia REPL on an ESP32. Julia uses LLVM to compile inputs to the REPL. That would probably need LLVM to run on the ESP32 itself.
Just a thought

Re: custom transport to carry MQTT over CAN/TWAI
Thanks for the brainstorming. abstraction API on top of MQTT That sounds reasonable and would happen entirely in user code. I think I'll follow your suggestion. Anything that would require me to change esp-idf would be near impossible to keep straight. I have upstreamed minor changes to esp-idf befo...

custom transport to carry MQTT over CAN/TWAI
Hi! In short: I'll need a custom transport to carry MQTT, which is not TCP-based. Is that doable? If yes, how could I do that, in broad strokes? I have a work project that uses MQTT in an ESP32. That works well over Ethernet. They now need the MQTT to be carried over CAN Bus. The "other side" has no...

Re: ethernet: need to configure two PHYs over internal MAC, but send no data
Thanks!
I've got it working. Not as clean as I'd hoped, and a bit of an adventure in the innards of IDF/HAL/LL, but simple in the end

ethernet: need to configure two PHYs over internal MAC, but send no data
Hi. I'm planning to connect an ESP32 to two Ethernet PHYs, but only the SMI (MDC+MDIO) and reset pins, not the data plane ( see docs ). For the data plane, both PHYs are cross-connected. I don't need the `netif` parts of esp-idf for this. I need to configure those PHYs, i.e. read and write registers...

Re: Wifi FTM and external APs
According to https://people.csail.mit.edu/bkph/ftmrtt_aps Google WiFi only does FTM on the 5 GHz band, not the 2.4 GHz one. ESP32 currently only do 2.4 GHz WiFi.

Re: Fail test Wi-Fi FTM RTT with ESP32-S2 and Android Smartphone (over 9)
I'm trying this on v4.3.1 and it still doesn't work right.
The app says "Requesting...".
I can only get it to show any values when my phone tries to connect to the ESP32-S2 running the ftm example.
I've experienced some kind of rate limit even between ESP32. Maybe it's that.
