I am sending data from iOS to a nRF5340DK. I have some code showing the TX/RX MTU Size:
void mtu_updated(struct bt_conn *conn, uint16_t tx, uint16_t rx) { mtu_rx = rx; mtu_tx = tx; LOG_DGB("Updated MTU: TX: %d RX: %d bytes", mtu_tx, mtu_rx); }
Which shows:
Updated MTU: TX: 527 RX: 498 bytes
But on the iOS/Controller side I have code:
let mtu = maximumWriteValueLength(for: .withResponse) print("mtu: \(mtu)")
Which shows:
mtu: 495
I also wanted to confirm the write from the controller is the RX for the peripheral, right?
