    Hello, Likely either EMC or a power force dip. Make sure the power supply of the ESP is well-isolated from the contactor coil. Thanks & Regards Nidhi Singh

    Yes, the C3 always needs a crystal to do anything, including flashing.

Hello everyone,

Is it possible to pair an Apple Magic Trackpad( 1. gen-> Bluetooth Classic2.0) with the ESP32? How simple is that? Can I be sure it will work?

I’m asking as I had a hard time changing any projects doing similar effects, even with Bluetooth keyboards.

Thank you in advance!

    Try using a cell phone app like" Bluetooth Terminal HC- 05" If you can pair and receive data with this from the trackpad also you can do it with an ESP32. It's my goto App for looking at data streams from Bluetooth.

    Hi,

    LoRa itself is a PHY that can be used in all network topologies. Mesh networking expands the range of the network, but reduces network capacity, At the expense of synchronization overhead and battery life reduction, due to synchronization and hop count. It is necessary to extend the distance with a mesh network architecture, so LoRaWAN chooses a star architecture to optimize network capacity, battery life, and easy installation.
