- SARA-R4 / SARA-N4 - 64 pins
o When a non-testable pin is selected, the command does not return an error result code but the value is
not considered and not applied.
o The status of the n-th pin will be represented by the corresponding n-th bit; see the <op_code>
description for the notation of each mode setting
o Convert each group of four binary digits into its hexadecimal representation
SARA-R4 / SARA-N4
See the End User Test Application Note [133] for the list of pins available for testing.
• An example of the AT commands sequence to test the digital pins is reported in Table 14.
Command Response Description
Configure the formatting of the error result code by
means of +CMEE AT command
AT+COPS=2 OK Deregister the module from the network
AT+UTEST=1 OK The module enters the test mode
AT+UTEST=10,2,"000007F400
C000D83F00"
OK The command puts the module in Interface initialised
state; the command saves the pins status to restore it
at the end of the test.
Pins enabled for testing: DSR, RI, DCD, DTR, RTS, CTS,
GPIO1, GPIO2, GPIO3, GPIO4, I2S1_RXD/GPIO6, I2S1_TXD/
GPIO7, GPIO5, I2S1_CLK/GPIO8, I2S1_WA/GPIO9, SPI_
SCLK/GPIO10, SPI_MOSI/GPIO11, SPI_MISO/GPIO12, SPI_
SRDY/GPIO13, SPI_MRDY/GPIO14
AT+UTEST=10,3,"0000049400
4000C01800"
OK Pins configuration:
o DTR, RTS, GPIO3, GPIO4, I2S1_RXD/GPIO6, GPIO5,
I2S1_CLK/GPIO8, SPI_MOSI/GPIO11, SPI_MRDY/
GPIO14 as input
o DSR, RI, DCD, CTS, GPIO1, GPIO2, I2S1_TXD/
GPIO7, I2S1_WA/GPIO9, SPI_SCLK/GPIO10, SPI_
MISO/GPIO12, SPI_SRDY/GPIO13 as output
AT+UTEST=10,4,"0000036000
8000182700"
OK Digital logic value of the output pins:
o DSR, RI, DCD, CTS, GPIO1, GPIO2, I2S1_TXD/
GPIO7, I2S1_WA/GPIO9, SPI_SCLK/GPIO10, SPI_
MISO/GPIO12, SPI_SRDY/GPIO13 set to "high".
AT+UTEST=10,5 OK Configurations made by AT+UTEST=10,2; AT+UTEST=
10,3 and AT+UTEST=10,4 are executed.
AT+UTEST=10,6 000007F400C000D83F00
OK
Logic digital value measured at modules pins:
o DSR, RI, DCD, DTR, RTS, CTS, GPIO1, GPIO2, GPIO3,
GPIO4, I2S1_RXD/GPIO6, I2S1_TXD/GPIO7, GPIO5,
I2S1_CLK/GPIO8, I2S1_WA/GPIO9, SPI_SCLK/GPIO10
, SPI_MOSI/GPIO11, SPI_MISO/GPIO12, SPI_SRDY/
GPIO13, SPI_MRDY/GPIO14: "high" level detected
AT+UTEST=0 OK Module exits from the test mode and normal pins
configurations is restored.
Table 14: Digital pins test command examples
The digital pins can be configured as many times as needed by the testing process; AT+UTEST=10,2
command is not needed any more as the DUT is already in Interface initialised state.
