Hi,
I am interested in increasing the BLE range of the ESP32C3 and I’m a little confused about BLE 5.0 vs 4.2, as I understand it BLE 5.0 is long-range.
Is BLE 5.0 purely a hardware-level change( that the programmer doesn’t see) or are there software-level changes?
I notice there are configuration options for BLE 5.0 in the menu config, how should this be configured?
If there are software-level changes are there any examples of BLE 5.0 used as a GATT server?
Thanks
You have to use ESP_BLE_GAP_PHY_2M or ESP_BLE_GAP_PHY_CODED settings (just play with settings). https://github.com/espressif/esp-idf/blob/master/examples/bluetooth/bluedroid/ble_50/ble50_security_server/main/ble50_sec_gatts_demo.c#L52-L54

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.

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
