Can not import escape from jinjia2

[prgrobots]

Using ros2 topic pub -1 /hadabot/blink_led std_msgs/msg/Int32 "data: 3" does not blink the ESP32. Can confirm it was flashed correctly and has connected to the network.

When running the docker I see python errors. Tried on 2 linux machines, Lubuntu and Ubuntu 22.04 and have the same general error :

I think its related to jinjia not using escape in versions latter than 1.something. Tried to install a earlier version which had escape but this didn't seem to fix everything and it still didn't blink.

Connected the pico in Thony..

I flashed the lattest versions of micropython, I couldn't download the suggested (I hope it didn't have any pre-compiled modules)

Using Thonny I installed the missing micropython-logging, but the next error :

INFO:__main__:Welcome to Hadabot - www.hadabot.com WebREPL server started on http://192.168.0.142:8266/ Started webrepl in normal mode Traceback (most recent call last): File "main.py", line 1, in <module> File "uhadabot/uroslibpy/__init__.py", line 11, in <module> File "uhadabot/uroslibpy/ros.py", line 3, in <module> File "uhadabot/uroslibpy/uwebsockets/client.py", line 12, in <module> ImportError: no module named 'ussl' MicroPython v1.23.0 on 2024-06-02; Generic ESP32 module with ESP32 Type "help()" for more information.

I think needs to be installed before the firmware is flashed? https://stackoverflow.com/questions/74977591/how-can-i-get-the-ussl-module-for-my-micropython-project

Thonny can't install it..

flashed this version, initial errors gone... https://micropython.org/resources/firmware/ESP32_GENERIC-20210418-v1.15.bin

Now onto : INFO:main:Welcome to Hadabot - www.hadabot.com WebREPL daemon started on ws://192.168.0.142:8266 Started webrepl in normal mode Network connected.

Got it working!!

I am using an ESP32 for testing without chassis so had to: Comment out all OLED code in main on ESP32. - There is no OLED in the kit? Remove ["as_ap"] from line 267 in main.py. Line 180, comment out the range sensors - # self.rs_set = RangeSensorSet(ros)

I would have imagined that these items would have been able to be flagged as "onboard" or similar in the config?

Will start a PR at some point.

Hope this helps others :)
