How to use PAN1780 (BLE module) with STM32L433 ?

[Starmaxou]

Hi everyone,

I am currently carrying out tests to choose a BLE module for future development.

The system is as follows:

• An STM32L433 manages the application side and controls the module in charge of BLE communication
• A BLE module which contains the Bluetooth part (GATT, GAP, etc.) and is controlled by the STM32L433

The communication between the two parts is a UART link.

I succeed to control a BGM220P Silicon Lab module with the STM32. But I am unable to set up this type of operation with a Panasonic PAN1780 module which uses a nRF52840.

In the Nordic environment, this is called "serialization".

Here are links to Nordic documentation on the subject :

• Porting serialization libraries
• Serialization
• Running a serialized application

Here is the dev kit for PAN1780 that I am using. (part-no : ENW89854AWKF)

 

Could people who have already made this kind of application guide me on how to set up communication between the STM and the nRF module?

Thank for your reply
