SPI Support and Configuration on EC200A-EU Module

IoT Modules LTE Standard Module

Hi,

I recently purchased the EC200A-EU module, and I plan to connect it to an STM32 microcontroller. I’ve reviewed multiple documents related to this module, and while two of them mention SPI connections, they don’t provide details about its implementation. I have a few questions:

  1. Does the EC200A-EU fully support SPI communication? Can I use SPI to send and receive data and send AT commands?
  2. How can I configure the EC200A in SPI slave mode? Are there any specific commands or settings required?
  3. The documentation mentions that the EC200A operates at 1.8V logic levels, while my STM32 uses 3.3V logic levels. Do I need a level shifter for SPI communication?
  4. Are there any application notes, example code, or detailed documents available specifically for setting up SPI communication with EC200A?

I’d appreciate any guidance or clarification on this matter.

The EC200A standard solution does not support SPI, but the OPEN solution supports SPI
