Help in prototyping a new Meshtastic device based on the seeedstudio WM1110-A tracker

Development Hardware
1

Hi Meshtastic People!

I’m willing to create a tracker based on the Wio Tracker 1110 Dev Board from Seeed.

In order to do that I’ve asked on the discord, and followed these instructions:

At this point I tried to look for the board from the smartphone meshastic app. A device showed up, but after 10 attempts it could not connect.

If I read the platformio.ini file [2] I see the default_envs parameter set to tbeam. Don’t see any wio-dev-1110.

is this ok?

Also: how do I tell the board I have addedd a oled screen on the i2c, a pushbutton and a WS2813 LED?
In other words, this is my board in a dev level stage:

Any advice is appreciated!

Which environment did you choose when building and uploading? I believe currently the wio-e5 environment in that branch does not fit into the flash, so I don’t think building could have been successful. Unfortunately support for this is not ready and it if it would in the future, it’s likely only a stripped down version of the firmware.

3

I’m successfully building and uploading for that board, from that specific branch. Is that correct? Here is a screen grab of the whole process.

Not the wio-e5 but the WM1110 board.

It says success, but it doesn’t work. Any help appreciated.

Oh, sorry, I thought you were referring to the wio-e5.

Unfortunately the LR1110 is also far from working, there is no RadioLib support yet. The pull request also says “DOES NOT WORK”.

Hi.
Thanks for your replies. They are super useful indeed.
Understood, Wio tracker dev needs some time to be added.

I have a Wio-E5-LE Dev Kit as well. How can I use this to prototype a meshtastic device?

What I did:

  • switch back to master (because apperntly is supported)
  • commented ;default_envs = tbeam and uncommented default_envs = wio-e5

When I try to build it says this.
What am I doing wrong?

Thanks in advance for your help, you are great.

Unfortunately as I mentioned is that device also not yet supported. It doesn’t fit in flash and the file system is not working.

thanks for your replies!

So it’s now working for you?
Did you follow my process?

11

Support has been merged already, currently a collaboration effort

12

Thanks to those who worked on the support!

Currently testing the Wio-WM1100 Tracker Dev Kit.

Basic questions as I go:

  • Does this thing have DFU? Double tap on the reset button doesn’t appear to change anything.
  • Maybe this one needs a Jlink to add an arduino bootloader like the RAK4631-R ?
13

I found it works without any bootloader as the ch340c is connected to the nrf52840 usb pins

You can flash a merged SoftDevice and meshtastic fw but will need a RAK-DAP or other cmsis-dap to flash it over SWDIO

J-link are too expensive as even a rp2040 can be used with pyocd

Thank you very much for your reply!

I’m new to this. Would you be able to walk me through it in more detail?

I’ve tried connecting the DIO and CLK pins to GPIO pins on a Raspberry Pi 3 and configured openocd using a tutorial. However, that just gives the error “Error connecting DP: cannot read IDR”. edit: with the Raspberry Pi it helps if you use the correct GPIO numbers (i.e. broadcom, not Pi4j!) I can now get a connection. I got ‘blinky’ working. Continuing to investigate …

I’ve also tried using various tools to try and work with the USB connection, but those either complain of the device not being in DFU mode, or not being able to detect a probe.

15

Oh ok, since you able to use it

Send me a pm

We just need the hex file and use a openocd command or use the telnet interface

You could use a Pi to program the Wio Tracker (kudos to Peter Pan at Seeed).

On my side, I’m still lost on which firmware is to be sent, but I have to re-read this thread (I started) from the beginning to the end with 1 hour free from BS in front of me

@vongomben

It not needed as the wio-tracker-wm1110 ships with a UF2 bootloader, just double press reset and paste in the drive letter uf2 file below

here
firmware.uf2 (1.3 MB)

He does not appear to show the actual SWD connection he made via 6pin or SWD+Trace pads ???

the 6pin needle cable is expensive and the SWD+Trace pin out is incorrectly documented on Seeed web site

Anyhow I found correct pins and tested flash via pyocd (rp2040 debugprobe)

Just confirming that thanks to @mark.birss 's guidance and magic uf2 file, Meshtastic is now running on my Wio-WM1100 Tracker Dev Kit!

It did require a raspberry pi running openocd with GPIO pins hooked up to DIO and CLK. I’ll write up some step-by-step instructions soon.

Here’s a quick write-up detailing how to flash Seeed Wio-WM1110 Dev Kit with Meshtastic:

I’m going to try updating the official docs a bit later.
