QuecOpen - BG95 - I2C - EVB

Hi
Happy new 2020…

Where is connected on EVB board:

  • QAPI_I2CM_INSTANCE_001_E
  • QAPI_I2CM_INSTANCE_002_E

Some info? … please

I found them …

For anyone else looking for this, on the EVB board, I2C shows up on AP_READY, W_DISABLE_N, J805 pins 3 and 5.

QAPI_I2CM_INSTANCE_001_E - yellow & green

Hi, I was trying mqtt sample code with i2c_scl and i2c_sda pins on evb board but it was not working.
Do we have any i2c at commands for bg95-m3. And also can you let me know which pins I have to connect like AP_READY — SCL and W_DISABLE_N ---- SDA

AP_READY is SDA
W_DISABLE_N is SCL

No, I don’t believe there are any I2C At commands.

Also, the I2C is 1.8v, so you need to either use 1.8v peripherals or a level shift.

without level convertors work fine ( LCD and sensors @ 3.3v )
BTW: 90% from GSM chipsets, the GPIOs is VBAT-tolerant…

Hello everyone,

I found out that you can use the I2C_SCL (pin 40) and I2C_SDA (pin 41) i2c port if you use QAPI_I2CM_INSTANCE_004_E as the i2c instance.
