Re: CPX Stalls

Awesome - thanks!

In my experiments it didn't matter if the GAP8 had a "sink" for the messages or not. The issue goes away when sending data with 1Hz in the STM32 app. Of course, ideally we would like to send with 20 to 100 Hz (depending on how fast the motion is).

Re: CPX Stalls

I tried again with the latest main/master, since there were lots of CPX changes recently. Unfortunately, I still have the same problems. If you need the detailed code:

CPX Stalls

I am using the latest aideck-esp-firmware, aideck-gap8-examples (with the wifi_jpeg_streamer), and crazyflie-firmware (i.e., all main/master branches). So far the demo works fine, and I get about 10fps when using opencv-viewer.py. However, once I add a very simple functionality in the crazyflie-firm...

Re: WiFi Connectivity Issues

Hi Tobias!
Wow, mystery solved. Now it seems to boot up consistently. Thanks!
Is that problem limited to the Olimex and do you know any JTAG programmer that works a bit more robustly?

Re: WiFi Connectivity Issues

Small update: I see the same stall/hanging now (for trying to access the camera) when using `make run`. It just seems less likely to trigger this issue compared to executing from flash.

Re: WiFi Connectivity Issues

Hi Kimberly, Thanks for your generous offer! I debugged this further today (using the logging output over UART). The issue is that the GAP8 seems to stall everytime in open_pi_camera_himax , independent of the AI deck I use. However, if I use `make run` it works fine. Thus, I don't think this is a h...

Re: WiFi Connectivity Issues

Thanks for checking! FYI, I tested with three brandnew AI decks with the stock GAP8/ESP32 firmwares and worked mostly fine. In one case, the connection was lost with the same symptoms, but could be revived with the 3 steps: turn off WiFi (PC), reboot CF, turn on WiFi (PC).

Re: WiFi Connectivity Issues

Thanks for your help - good to know that this is not normal! - We flashed using the Olimex. - Yes, we tried to restart the Crazyflie, both with the button and also by re-plugging the battery. - By software access point I mean that the NINA is creating an access point (similar to a router), and we co...

Re: Logging GAP8/ESP32

Thanks, Marcus! It would be nice if this can go to the documentation (or be pinned here:-). Also, it might make sense to list additional recommended products on the product page. It seems like for the AI deck for development one needs at least the Olimex and the USB-to-serial dongle (right now). Fin...

Logging GAP8/ESP32

We are using the new wifi streamer example (https://github.com/bitcraze/AIdeck_examples/tree/cf-link/GAP8/test_functionalities/wifi_jpeg_streamer) with the provided GAP8, ESP32, and STM32 firmware versions. In the GAP8 firmware, in test.c, there are printf statements used. How can one see the printf...
