I am using BC127 with Melody 7.3 bluetooth stack.
I am wondering if this is possible to send binary data using AT oommands ? Or enabling a “data” mode using AT commands. I cannot used BLE/SPP/HID to transfer the raw data, it needs to be HFP.
Thanks a lot for your help !
No, it enters Data mode on a BLE, SPP, or iAP link.
I am looking to use HFP link.
HFP (Hands Free Profile) is an audio link, not a data one so I am not sure what you mean by wanting to send data over it?
But AT commands are passed through HFP link ?
I am wondering if possible to do OTA using HFP link ?
No you cannot push data over the HFP.
