After aframe of data is sent, the pin will be pulled low again.Send Bluetooth data:After the DATA pin receives the data on the RXD pin of BT52,the buffer BUFF size is 2K. As long as there is data in the BUFFthat has not been sent out via Bluetooth, the DATA will be pulledhigh. It will be pulled low again until the data transmission in theBUFF is completed. The user can use the above description to dodata framing. |
