Overview

Wifi on ESP32C3 (on bare-metal Rust)

About

This is experimental and work-in-progress! You are welcome to contribute but probably shouldn't use this for something real yet.

This uses the WiFi driver found in https://github.com/espressif/esp-wireless-drivers-3rdparty

Version used

esp-wireless-drivers-3rdparty-055f1ef49d0cb72c24bd492fbbdd37497a90bdae 45701c0

https://github.com/espressif/esp-wireless-drivers-3rdparty/archive/45701c0.zip

Example

dhcp
- set SSID and PASSWORD env variable
- gets an ip address via DHCP
- it prints the ip address it gets
- if everything works you should be able to ping and connect to port 4321

What works?

scanning for WiFi access points
connect to WiFi access point

Directory Structure

src/timer.rs: systimer code used for timing and task switching
src/preemt/: a bare minimum RISCV round-robin task scheduler
src/log/: code used for logging
src/binary/: generated bindings to the WiFi driver
src/compat/: code needed to emulate enough of an (RT)OS to use the driver
- malloc.rs: a homegrown allocator - this is NOT used on the Rust side (the Rust side of this is currently no-alloc)
- common.rs: basics like semaphores and recursive mutexes
- timer_compat.rs: code to emulate timer related functionality
headers: headers found in the WiFi driver archive (bindings are generated from these)
libs: static libraries found in the WiFi driver archive (these get linked into the binary)
mkbindings.bat: generate the bindings / just calls bindgen
rom_functions.x: the WiFi driver uses some of these so it needs to get linked
esp32c3-wifi-link.x: the main linker script - needs to get cleaned up
examples/dhcp.rs: example using the code

Missing / To be done

separating chip specific / architecture specific code (and create implementations for others)
Bluetooth (and coex)
esp-now
powersafe support

Update embedded svc

This is based on the #82 branch, so until that's merged this is blocked. I only implemented the Wifi trait on the Wifi struct, but where should I implement the Interface trait. This contains the actual IP info, should I directly implement it into Wifi or should we change places into Network, what should we do with the poll_dhcp function then in Wifi

Closes #83

Remove the embedded-nal / smoltcp-nal dependencies from `wifi_interface.rs` and esp-wifi
While smoltcp itself has no alternative in the embedded world, I'm less than convinced that embedded-nal is the no-brainer for embedded networking: it still relies on the nb "async" approach, which is essentially just busylooping with constant polling of the networking layer. While this might have been the norm a few years ago, it is no more:

embedded-hal is moving away from nb in favor of the async-based traits

smoltcp itself has an async support and an async feature since quite some time, so it is very easy to bind it to an async executor of your choice, if you prefer so

In my opinion:

We need to remove from esp-wifi all dependencies / reliance on embedded-nal / smoltcp-nal. This stuff is anyway a thin wrapper on top of the heavy lifting done by smoltcp itself

The Wifi struct can instead take directly the smoltcp IP interface, i.e. the "ethernet" var

This way, the create_network_stack utility will construct and return directly the smoltcp interface instead of the embedded-nal wrapper. Perhaps, we should rename the utility to create_network_interface or suchlike

The network_stack method of the Wifi struct should instead directly return the native smoltcp interface

With that little surgery, users would be free to either use smoltcp-nal on top of the smoltcp interface returned by Wifi, or the smoltcp built-in async facilities, with an async executor of their choice.

DHCP example fails to get an IP address on ESP32-C3

Hi, I tried running the DHCP example (commit a0a6b5fbcf7) on my esp32-c3-mini and it appears as though the code is racy. It fails to get an ip address, unless I do some random permutation of dump_packets, wifi_logs, and manually putting in for i in 1000 {} style loops.

I'm working with @ImUrX and he also cannot get the example working on his PCB, although his is a lolin_c3_mini v1.0.0 (which may have hardware issues with wifi, so could be a red herring).

If I use --release it works consistently.

dhcp_esp32c3 example fails to get an IP address when compiled in Release

When the dhcp_esp32c3 is ran in release it hangs at Start busy loop on main and never continues. This same dhcp_esp32c3 example gets an IP address from DHCP as expected for me when it's ran in debug.

Getting linking issues when using esp-wifi

I was adding esp32 support to my esp32c3 project and for some reason I'm getting linking issues when activating the esp-wifi feature I have. I honestly dont understand much so maybe I can get some help in here: This is the linking error and this is the project

Update drivers
This closes #52

While this PR seems to be huge, it isn't. Most of the changes are in C headers and generated bindings.

Swap out the current allocator for `esp-alloc`

~~This builds on #39, and as such cannot be merged until that PR is.~~

This works on the ESP32-C3 without issue, however building for the ESP32 results in a linker error:

error: linking with `xtensa-esp32-elf-gcc` failed: exit status: 1

Not sure why dram_seg is overflowing. Reducing the heap size allows it to build, but results in runtime errors instead.

Can't connect to any AP?

I've been playing around trying to get this work. Scanning works perfectly, I can see a table of networks near me, but If I try to connect to any (I've tried 4 in total, on two different esp32c3's), the WiFi state never transitions to STA_CONNECTED. Judging by the logs below is transitions to STA_STOP.

Feature Request: UDP Sockets

I'm interested in using a esp32c3 to received UDP packets. I've been playing with the DHCP example and it looks like it is working quite well (kudos!) and I'm excited to use this more - is there any chance that UDP support is coming soon?

WiFi for ESP32-C2

This implements WiFi for ESP32-C2

Please note that to run the examples you need to change Cargo.toml as explained in the README since we cannot have feature-dependent dev-dependencies

Double Check Wrapping Behavior of Timers

Several functions include blocking behavior or generally deal with timers - double check them for the wrapping behavior of the timers Also note that the timers on different targets have different bit-widths

Support async

Would be very nice. I haven't actually read a lot on how it should work. We would first need embedded-svc to implement an async trait which is nightly. But I see a lot of calls like scanning that could be async and it would be pretty nice to have that, I also see that smoltcp implements Wakers for their socket stuff, could we also have async sends and receives :astonished:?

Support `direct-boot` mode

So far I've been really appreciating tools like defmt-rtt, cargo embed, probe-rs etc. I believe these tools are only possible with the direct-boot mode of esp-hal. Therefore it would be awesome to add support for using esp-wifi in direct-boot mode.

Does anyone have any guidance for someone looking to implement this? I assume its all to do with how the linker script works.
