hello everyone ,

i have two devices: one designated as the master and the other as the slave. The slave device will receive input strings via RS-485 and subsequently transmit these strings to the master device using Zigbee communication in esp32-c6

right now both the devices are connected via zigbee network i am getting bound successful message, slave are sending the string to the master but master is not entering in indication callback because master short add is 0 i.e master is acting as a coordinator, and coordinator will not enter the data indication callback and not receive message like end device do. so anyone can help me regarding this issue...i am attaching me code for reference


slave side code i.e transmitting the string to the master

}
