BT02 does not support one master and multiple slaves. E74 can send BT02 slaves to the master. The serial port baud rate of 19200 and below can support continuous transmission. At this time, users can send data with any packet length at any time. The master sends to the slave, preferably no more than 20 bytes at a time.
moreIf there is no
adsorption, adsorption is recommended; there are two options:
1. Replace the antenna of the transmitting end with TX433-XPH-300,
2. Try replacing the antenna of the receiving end with TX433-JK-20, and at the same time, the suction cup is adsorbed on the iron sheet.
The tool we use is XDS100V3.0 JTAG interface.
morePlease re-power on and test it with the latest version of the parameter configuration software.
moreThe problem caused by the short circuit of P0.3 (TXD) and PROG pin; please contact the technical staff for detailed solutions.
moreCheck if the jumper cap is connected correctly.
morePlease determine how many volts is the power supply? Are the antennas matched?
