Hello,

I bought on aliexpress a couple XIAO ESP32S3 & Wio-SX1262 for meshtastic
it works very well but it is impossible to change the firmware,
on the ESP32S3 model there is no boot and reset button as indicated.
Only 1 button on the SX-1262 so it reboots but impossible to switch to boot loader mode to change the firmware. The com port is there for the flash and available on the computer.
There is nothing indicated on the wiki except if you have the 2 button model on the XIAO ESP32S3…
I may have missed something …
Thanks in advance for your answers

Hi there,
and Welcome here…

Ok So, is it a real Xiao from Seeed studio?
If so Is it a two board sandwich ? The bottom board is the Xiao and the top Board is the Mesh_radio. The buttons are tiny and check the WiKi for more info it’s all there.
Check this too… “1:40:00” Listen closely and do exactly this way… Success will be yours :index_pointing_at_the_viewer:

Hi
I have updated the Meshtastic FW using the tiny buttons okay basically holding down the program button while inserting the USB cable.

The issue for me is that the boards have to be separated every time you need to undate the firmware.

Has anyone got the 1200 BPS reset to work?

Is this something Meshtastic would have to put in thier FW or is this a Seeed issue?,

go to https://flasher.meshtastic.org/

Also read wiki

Reset and boot button should not be needed… but they are small and next to USB

May have to separate two boards… also may have to remove power

also press and hold boot… press reset… release boot

Thanks to all answers
I found the 2 buttons on the ESP32S3 but it doesn’t look like buttons … they are filled with solder, nothing protrudes from the button as indicated on the wiki, but by insisting I see that it sinks slightly.
not easy …

I’ve found it’s still impossible to update the firmware using Meshtastic’s web flasher (Mac/Chrome). Following the instructions in the videos on the Wiki for this product, the device refuses to reconnect after the reboot/rest button sequence shown (which is a pain to accomplish to start with - it’s basically a 3 hand procedure). I’m left with “Connecting…” and that’s it. After 2 hours, I gave up. Thankfully, an older version of Meshtastic firmware comes pre-installed, but my hopes of updating it are nil. Searching on the web I find there are many others with the same issue.
