Are these 2M and LE Coded PHY modes default to Bluetooth communication at kernel level or is there any way we can select while establishing Bluetooth communication from iPhone to the sensor device? My problem is that with Latest Bluetooth 5.2 it is default set to LE Coded Phy . which results in the reduced data thought rate. So would like to set the 2M mode while searching for Bluetooth sensors. is it possible from IOS SDK?

Is it possible to set Long /Short mode connection after established? we need some capability to change the default of Blettoth 5.2 Long Mode to short mode so that we can achieve better data thought put to speed. my original problem is as described below the sensor. we are using an external sensor to connect and get the accelerometer data. with New Firmware it's about 50% more time than with old Firmware .and approached the vendor he was saying ***** (sensor) is able to capable what Master (IOS iPhone device) and he said he unable to find to set PHY mode from Apple Core Bluetooth SDK. for brief understanding I have added the link of communication below. https://mbientlab.com/community/discussion/4076/observed-the-change-in-download-recorded-data-from-sensor-to-phone#latest

any news about this ?

Hi Regarding the request to use LE 2M PHY (if devices are capable)? how to use this connection I heard that the BLE 5 is defaulted to 1M PHY ? Can you provide any sample code ?
