I am trying to adjust the signal strength of the BLE radio on the MKR1010 u-blox NINA-W102 module, but I have not been able to find clear answers in the u-blox documentation.
I assume the signal strength is determined by the firmware and hardware settings within the module, and it is not directly adjustable through AT commands. However, I am looking for any possible methods or workarounds to adjust the BLE signal strength on the module to suit my specific use case.
Thanks.
doesn't signal strength depend on transmitter power, receiver sensitivity, antenna length, distance and obstructions? not much you can do about it with software
Of course, but on some devices, BLE included, you can also adjust the initial transmitter signal strength and by that play, for example, with the strength of emitted energy, hence the max range in which a client will receive such transmission.
hard for me to imagine any way to control transmitter power aside from its voltage. i guess your suggesting that voltage wouldn't be maximized to save power for some reason (e.g. battery life)
The SX1280 2.4Ghz LoRa device for instance, allows you to adjust output power from -18dBm to +12dBm in 1dBm steps.
