I am new to Bluetooth in terms of its use and deployment in the embedded systems particularly when it comes to the selection of BLE chips, BT stacks, profiles, etc. I am planning a project in which I would be needing a BLE chip (& stack) which:
1.) can connect to at least 7 external sensors hosting profiles like Heart-rate, blood-pressure, indoor positioning, location & nav, etc
2.) can simultaneously act as a host to let an external wireless remote LCD display connect to it and send/receive display/HMI data to (maybe using some customized profile, etc)
I am looking for advice in terms of selection of the best BLE chip (& vendor) possible which has good support in terms of ecosystem/dev-tools, shorter time to market, etc. Also, I wanted to know if these BLE profiles can be integrated into the BLE chip's firmware itself that can be selected and controlled through an external host MCU, or is it also possible that these profiles can sit on the external host MCU itself.
Thanks in advance!
