In part #4, in particular in the &quot;publishing data over BLE&quot; part, the code is missing the declaration of the variables &quot;oldposture&quot; and &quot;update posture&quot;. We&#39;re having problems introducing them, we were wondering if you could help us. By the way you&#39;re job is amazing, congrats!</li> </ul><img src="https://community.element14.com/aggbug?PostID=11190&AppID=279&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/challenges-projects/design-challenges/design-for-a-cause-2021/b/blog/posts/trakcore-4-ai-assisted-posture-modification---enabling-imu-and-ble-with-edge-impulse-ml-on-arduino-nano-33-iotThu, 22 Apr 2021 19:13:04 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:cbd81592-e1ad-481d-a1cd-33a577fb0b2aDAB1<p>Looks like you need to have a lot of detail about setting up the interfaces.</p><p>&nbsp;</p><p>DAB</p><img src="https://community.element14.com/aggbug?PostID=11190&AppID=279&AppType=Weblog&ContentType=0" width="1" height="1">
