^ Choosing a test-able GPIO for GPIO demo app
Following GPIO pin table from QuecOpen gpio demo app:
52 /* !!! This Pin Enumeration Only Applicable BG95-OPEN Project !!!
53 */
54 #if defined(_QUECTEL_PROJECT_BG95)
55 GPIO_MAP_TBL gpio_map_tbl[PIN_E_GPIO_MAX] = {
56 /* PIN NUM, PIN NAME, GPIO ID GPIO FUNC */
57 { 4, "GPIO_01", 24, 0},
58 { 5, "GPIO_02", 21, 0},
59 { 6, "GPIO_03", 22, 0},
60 { 7, "GPIO_04", 23, 0},
61 { 18, "GPIO_05", 3, 0},
62 { 19, "GPIO_06", 2, 0},
63 { 22, "GPIO_07", 1, 0},
From document Quectel_BG95BG77BG600L_Series_QuecOpen_Application_Note_V1.4.pdf, page 23, it appears that BG95 pin 18 has signal/port name GPIO5, which in turn can be configured to be GPIO_3 or I2C1_SCL. This matters because the eval board breaks out a limited number of test pins on J803, J805, J806 and J804. On J804 there is a pin designated as I2C_SCL. In document Quectel_BG95BG77BG600L_Series_QuecOpen_Application_Note_V1.4.pdf there are references only to I2C1, not any other numbered I2C peripheral.
