Bluetooth data Transference

[pablogurjao]

Hi, I'm working with esp32 and I'm trying to make a transference of data from my esp32 to any device, but this data has approximately 1.5Mb, I already try ble, but his throughput is very low, I only getted until now 2kbits/sec. I'm trying the classic bluetooth now, but I dont know wich protocol do this kind of transference, I'm using the RFCOMM now, but I don't know if that's protocol is the right one, I hope that someone can help me.

Thanks

Did you try to change MTU to 500-ish in ble? its about 25 times faster than normal (mtu = 23).

yes, I tryied with mtu 500, but I've no success, the throughput is very slow, I don't undestood what is happening, because I'm using the examples of esp-idf.
