I have a Nucleo pack. I loaded the Bluetooth test files (.HEX) into the main board and the dongle that comes in the pack and the code is working as explained. However when I compiled (Hex code not provided) and loaded ZigBee code, the unit is displaying error by all three LEDs flashing (as per manual). I thought the ZigBee binary might not have loaded and tried to check. ST has provided a Command Line Interface (CLI) program to read/program the co-processor. When I try to read the FLASH of the co-processor, I am getting only 00s, though I disable read protection. I would like to first check if ZigBee binary is loaded or not and if it is not loaded I would like to load it. Can someone help me in this regard please? Thank you for your time.
