Hi. i am testing the new product: XIAO MG24. As written in the documentation of the product the onboard antena can have up to 50m. From the docs: “Equipped with an on-board antenna with BLE range up to 50m in an open location with no signal interference, while reserving an interface for external U…

Hi there, I might add, that BLE at that distance usually means coded PHY mode for Longer range. Not even the original BLE 5.0 spec is 50 meters so IDK where they are getting the “SALES” info from? this say’s :saluting_face: Typical BLE Range By default, Bluetooth Low Energy (BLE) devices often …

Hi potocnik, [image] potocnik: With my testing on examples provided in the library, i cannot get more than 3m. What it says 50m is really an ideal value in an ideal environment. Practically speaking, it’s 10m at most. What antennas did you use and which sketches did you use on the transmitt…

plus there is so much background bluetooth traffic its unbleavable…

I tried to use w/o antenna, and was surprised when they said 50m :smiley: The receiver was phone, for testing purpuses. Will try to setup some antennas to achive some more range than couple of meters

The transmit power of BLE can be changed from -3 dBm to 8 dBm. It may extend the communication distance a little. See the link below. [image] Antenna Comparison of XIAO nRF52840, ESP32C3, ESP32C6 and MG24 XIAO Now that the XIAO nRF52840, ESP32C3, ESP32C6 and MG24 with on-…

Hi @potocnik , I had the same issue and solved it by looking at the schematic of the MG24 board. The onboard antenna is not powered (there is a switch in between) in the Arduino IDE samples. Power to the antenna (switch) is provided by pin 5 of GPIO B. This is zero by default. Just set it to 1 and …
