0:00 Getting started
1:01 Hello, welcome to Deep Dive
1:38 Getting started
2:00 Circuit Python (CP) is a version of python for microcontrollers - example NRF52840 feather
4:00 Deep Dives are usualy on Friday's at 2pm pacific, 5pm eastern time
4:55 Chats on youtube or discord https://adafru.it/discord #live-broadcast-chat channel
6:37 Working on the Zephyr port, currently BLE ( blue tooth energy )
7:15 Address GAP and GATT in earlier episodes
7:24 Now addressing BLE workflow, talk to CP from phone or tablet
8:00 File Glider application learn.adafruit.com/file-glider/overview
9:00 looking forward to LLM assisted mobile app
9:45 using OBS noise supression filter
10:00 comments on stuttering/clipping on youtube
10:36 using the pi coding agent GLM5.2 open weight model
13:00 trying to use bluetooth simulator (BSIM) in the tests
13:49 this PR has bluetooth starting earlier, boot.py, and blink codes, then code.py
15:20 sublime merge review of pi LLM agent's code
17:10 allocation of memory changed, since allocation shouldn't happen early on
18:50 LLMs sometimes generate very wordy comments - need to watch that
20:00 BLE characteristics, could be a topic to discuss
21:40 GATT discussion
25:30 characteristic buffer and incoming/outgoing packet buffering
28:00 BLE workfile file and serial services
28:55 Zephyr build in BLE workfile
30:00 BLE lower level test cases ( need to be human readable )
33:00 BLE file transfer protocol in CP
33:55 check in with the BLE build progress
36:00 running GLM 5.2 via Klien Pass subscription ( was LLama cloud ) and other subscriptions
38:18 "make test"
40:00 return to the merge and draft PR from zephyr_ble_workflow #11226
42:40 Local LLMs (ds4: DeepSeek 4 ) looking at github antirez/ds4
44:40 Zephyr opinions/comments (e.g: kconfig and device tree)
52:28 Wrap up
