X-NUCLEO-PGEEZ1
Hardware Overview
Standard SPI page EEPROM memory expansion board based on M95P32 series for
STM32 Nucleo
The X-NUCLEO-PGEEZ1 expansion board is designed for the M95P32 series SPI page
EEPROM for data reading and writing.
This expansion board allows developers to evaluate the new memory page EEPROM
through a single/dual/quad SPI interface.
It acts as an external storage device that can be used to store data, such as
manufacturing traceability, calibration, user settings, error flags, data
logs, and monitoring data to build more flexible and accurate applications.

FOTA : Flash Layout BlueNRG-LP/LPS
Software Overview
- BlueNRG-LP/LPS Flash Layout
- OTA Service Manager stored in Flash Memory of BlueNRG-LP/LPS is used to carry out Firmware Over The Air (FOTA) update
- On device reset, Service Manager decides where the device should boot from
- Service Manager starts from address 0x1004 0000
- User Application starts from address 0x1005 7800
- User can jump from User application to Service manager to start OTA session by pressing “Reset” once and then holding “PUSH1” button pressed

FOTA – Procedure
- The procedure to setup BlueNRG-LP/LPS for FOTA can be divided in these steps:
- Step 1 : Erase complete flash memory
- Step 2 : Program Service Manager
- Step 3 : Perform FOTA
Step1 : Erase Complete Flash Memory
For BlueNRG-LP
- Open EWARM project :
- \STSW-BlueNRG-FOTA\Projects\Applications\BLE_OTA_ServiceM anager\EWARM\STEVAL- IDB011V1\BLE_OTA_ServiceManager.eww
- Go to Project → Download → Erase Memory and click on “OK” on the next popup to confirm erase of flash memory
- This step to be done only once
- Note: User can use any other tool also for complete flash erase
For BlueNRG-LPS
-
Open EWARM project :
-
.\STSW-BlueNRG-
FOTA\Projects\Applications\BLE_OTA_ServiceM anager\EWARM\STEVAL- IDB012V1\BLE_OTA_ServiceManager.eww -
Go to Project → Download → Erase Memory and click on “OK” on the next popup to confirm erase of flash memory
-
This step to be done only once
-
Note: User can use any other tool also for complete flash erase
 Step 2 : Program Service Manager
-
For BlueNRG-LP
-
Open EWARM project :
-
.\STSW-BlueNRGFOTA\Projects\Applications\BLE_OTA_ServiceMa nager\EWARM\STEVAL- IDB011V1[BLE_OTA_ServiceManager.eww](http://BLE_OTA_ServiceManager.eww)
-
Go to Project → Download → Download active application
-
The following will be printed on UART terminal:
-
OTA Service Manager is programmed successfully
-
| Signal | BlueNRG-LP | Jumper J8 on X-NUCLEO-PGEEZ1 |
|---|---|---|
| SPI1_SCK | PA13 | SCLK |
| SPI1_MISO | PA14 | DQ1 |
| SPI1_MOSI | PB14 | DQ0 |
| CS | PA11 | CS |
The project uses M95P32 External EEPROM mounted on X-NUCLEO-PGEEZ1 for FOTA
service which should be connected to BlueNRG-LP/LPS
Step 2 : Program Service Manager
- For BlueNRG-LPS
- Open EWARM project :
- .\STSW-BlueNRGFOTA\Projects\Applications\BLE_OTA_ServiceMa nager\EWARM\STEVAL- IDB012V1\BLE_OTA_ServiceManager.eww
- Go to Project → Download → Download active application
- The following will be printed on UART terminal:
- OTA Service Manager is programmed successfully
| Signal | BlueNRG-LP | Jumper J8 on X-NUCLEO-PGEEZ1 |
|---|---|---|
| SPI13_SCK | PB3 | SCLK |
| SPI13_MISO | PA8 | DQ1 |
| SPI3_MOSI | PB11 | DQ0 |
| CS | PA9 | CS |
The project uses M95P32 External EEPROM mounted on X-NUCLEO-PGEEZ1 for FOTA
service which should be connected to BlueNRG-LP/LPS
Step 3 : Perform FOTA (1/4)
- Take any Android or iOS device and launch the application “ST Ble Sensor Classic”
- Download the application from Play/App store if not already installed
- The example application demonstrates different LED toggle which can be selected from the defined macro in preprocessor
| BlueNRG-LP | CONFIG_LED_DL2 | CONFIG_LED_DL3 |
|---|---|---|
| Toggle DL2 with 250ms delay | Toggle DL3 with 1000ms delay | |
| BlueNRG-LPS | CONFIG_LED_DL3 | CONFIG_LED_DL4 |
| --- | --- | --- |
| Toggle DL3 with 250ms delay | Toggle DL4 with 1000ms delay |
- Save the example user application .bin files on the phone
- The binary file is first stored on external M95P32 EEPROM via Bluetooth transfer from phone and then internally copied to flash memory of BlueNRG-LP/LPS
- Here, the steps are demonstrated with an Android phone
Step 3 : Perform FOTA (2/4) 
Step 3 : Perform FOTA (4/4)
- Wait for user led U5 on BlueNRG-LP/LPS to turn-off which denotes end of FOTA update
- Device resets and application boots up based on the binary flashed
• The sample application demonstrates different LED toggle functionality which can be defined as a macro in preprocessor
FOTA – Application
| BlueNRG-LP | CONFIG_LED_DL2 | CONFIG_LED_DL3 |
|---|---|---|
| Toggle DL2 with 250ms delay | Toggle DL3 with 1000ms delay | |
| BlueNRG-LPS | CONFIG_LED_DL3 | CONFIG_LED_DL4 |
| --- | --- | --- |
| Toggle DL3 with 250ms delay | Toggle DL4 with 1000ms delay |
FOTA – Application
FOTA – Flasher Utility
If using a flasher utility tool, then the following steps should be
followed
- Erase complete flash
- Flash BLE_OTA_ServiceManager.bin from address 0x1004 0000
- Flash the required .bin from address 0x1005 7800
