I am trying to connect to a Polar HRM with a STM32WB55 Nucleo board by modifying the BLE_p2pClient example.
I tested the example and it worked in connecting to another ST board. Then I modified the code to connect to the UUID of the HRM I got from the scan, changing SERVER_REMOTE_BDADDR putting the UUID in reverse order. In the scan, I was able to find the exposed services to check if the scan was a success and got the UUID and RSSI from there. When I ran aci_gap_create_connection to connect, it returned a BLE_STATUS_SUCCESS, but I did not get a HCI_LE_CONNECTION_COMPLETE_EVENT like I did when I successfully connected to another ST board. I messed around with the connection interval, slave latency and supervision timeout, but still couldnt get the device to connect. I also am not seeing the complete name in the advertising data when I scan with the STM board, but I know its being advertised by checking with with a phone app and other device names are showing up as well.
I tried the same thing with another Polar HRM and a Whoop band. Whoop band did return the complete name, but didnt connect as well. Are there any other settings I should change to connect with other BLE devices successfully?
