Hi
I've read in a few places that the BLE spec requires a packet to be retransmitted if its checksum calculated at the receiver does not match the checksum sent by the transmitter i.e. error detection.
I want to confirm whether this is true, and that the ESP32 BLE stack using Bluedroid implements this automatically, or if this functionality must be implemented by the programmer.
Cheers

Re: BLE error detection
CRC check for over the air transmitted packets and re-transmission as required is done BLE Link Layer firmware as per BLE specifications.
