o
Baud rate : 115200
o
Data : 8 bit
o
Parity : None
o
Stop : 1 bit
o
Flow control : hardware (RTS/CTS)
RING signals the availability of URC from Monarch Go-GPS BLE modem and can be used to
wake-up the MCU on the host board
Warning
: The host board shall be compliant with below high voltage level:
o
V
IH
Input High Voltage (UART1 TXD/RTS)
min 1.26 V - max 3.6V
o
V
OH
Output High Voltage (UART1 RXD/CTS and RING)
min 1.35 V - max 1.8V
If the MCU on host board is capable of 3V only but not 1.8V, level shifters shall be added on
UART1 RXD, CTS and RING.
The below electrical signals on Monarch Go-GPS shall BLE be connected to test points on host board for
debug purpose:
UART2 2-wires RXD/TXD is the LTE modem console port. Default configuration :
o
Baud rate : 115200
o
Data : 8 bit
o
Parity : None
o
Stop : 1 bit
o
Flow control : None (no RTS/CTS)
Note: hardware flow control (RTS/CTS) is disabled by default even if signals are present on the
connector.
Warning
: the high voltage levels for these signals are:
o
V
IH
Input High Voltage (UART2 TXD/RTS)
min 1.26 V - max 3.6V
o
V
OH
Output High Voltage (UART2 RXD/CTS)
min 1.35 V - max 1.8V
GPS_UART1 2-wires RXD/TXD is configured for GPS console. Default values:
o
