In the configuration on computer, the module address, frequency channel, network ID, and key are all in decimal mode.
Chengdu Ebyte Electronic Technology Co.,Ltd E22-230TXXS User Manual Key: 0-65535 When the user configures the repeater mode using the host computer, special attention must be paid. Since the parameters are in decimal mode in the host computer, the module address and network ID need to be converted into hexadecimal.
Chengdu Ebyte Electronic Technology Co.,Ltd E22-230TXXS User Manual 11 FAQ 11.1 Communication range is too short The communication distance will be affected when obstacle exists. Data lose rate will be affected by temperature, humidity and co-channel interference. The ground will absorb and reflect wireless radio wave, so the performance will be poor when testing near ground. Sea water has great ability in absorbing wireless radio wave, so performance will be poor when testing near the sea.
