How would you do it? mpremote web browser

[patfrench]

I have several questions about my project:

• I have a RPI-PICO built with the WEBUSB version. port/rp2: Added WebUSB to RP2040. #11301

• I've developed a javascript code that connects to the RPI-PICO via USB and gives me access to the REPL. Tested with
  https://example.tinyusb.org/webusb-serial/

• I've added "pyscript" to the javascript, so I now have a python interpreter in my browser.

• I've installed mpremote in my browser's python environment
  https://titeppat.pyscriptapps.com/tight-bonus/latest/

• I'd like to use mpremote but I'm lost.

• I need to replace pyserial with my USB connection ?

• I need to be able to use mpremote in the browser interpreter ?

is this possible? Do you have any suggestions ?

Thank you

If you look at /tools/mpremote in this repo the current version might be easier to follow, the transport_serial file handles all the communicating.

I'm not sure about python in the browser though, whether it's possible to get read/write stream date out to a JavaScript function which could then forward it on to the webusb functions.

Ok

I saw that Jeff Glass did the same thing with the WEBSERIAL API. https://jeff.glass/post/pyscript-webserial/
I'll have a look

I need to know if i can use mpremote as a library ? can i do like the pyboard.py utility ?

pyb = pyboard.Pyboard('/dev/ttyACM0', 115200)
pyb.enter_raw_repl()
ret = pyb.exec('print(1+1)')
print(ret)
pyb.exit_raw_repl()```

thank you

Mpremote currently does not have a well defined api, there is a PR with a partial implementation

#11777

Hi,

Finally, I write the functions in javascript. I don't have enough skills to transform mpremote or pyboard.py

I still need your help:

The version of micropython https://github.com/KitronikLtd/micropython-rp2-webusb is 1.19

And I use a PICO_W, I don't know how difficult it is to recompile firmware to version 1.20.

Because I would like to have access to "import bluetooth ".

Thank you

Regarding BLE, which devices do you usually test with? Do you need to run a special firmware for this?

[patfrench]

hi,

for the BLE, i use : https://github.com/micropython/micropython/blob/master/examples/bluetooth/ble_uart_repl.py

In my file system there is :

and in my main.py (maybe in boot.py it would have been better)

import ble_uart_repl

thank you

[patfrench]

ble_uart_repl will work with original firmware.

for webusb no, it's a custome firmware, i don't use webserial.

for your android version: how does it work? with webserial?
