| 1 | 16-bit | Length | Number of bytes between the length and checksum. |
| 3 | 8-bit | Frame type |
Modem Status - 0x8A |
| 4 | 8-bit | Modem status |
Complete list of modem statuses: 0x00 = Hardware reset or power up 0x01 = Watchdog timer reset 0x02 = Joined network (routers and end devices) 0x03 = Disassociated 0x06 = Coordinator started 0x07 = Network security key was updated 0x0D = Voltage supply limit exceeded—see Over-voltage detection in the XBee 3 RF Module Hardware Reference Manual. 0x11 = Modem configuration changed while join in progress 0x3B = Secure session successfully established 0x3C = Secure session ended 0x3D =Secure session authentication failed 0x3E = Coordinator detected a PAN ID conflict but because CR = 0, no action will be taken. 0x3F = Coordinator changed PAN ID due to a conflict 0x32 = BLE Connect 0x33 = BLE Disconnect 0x34 = No Secure Session Connection 0x40 = Router PAN ID was changed by coordinator due to a conflict 0x42 = Network Watchdog timeout expired three times 0x80 - 0xFF = Stack error |
| EOF | 8-bit | Checksum | 0xFF minus the 8-bit sum of bytes from offset 3 to this byte (between length and checksum). |
