Need to select nRF52832 Peripheral example code

[beemavishnu]

Hello,

 

I am new to Nordic and started using nRF52832. We started a new project. It requires

 

1. Act as Peripheral (Single role) only.
2. Only Advertisement for 3 minutes (Limited Discovery) when button is pressed.
3. Sleep and wakeup based on configuration (It can be between 1 min to 30 min).
4. After wakeup, write data into Flash.
5. SPI, I2C interface.
6. Establish BLE connection to read data from Flash.
7. Image up-gradation over BLE.

 

I saw couple of BLE Peripheral example codes.

My queries are:

1. Whether can I use “ble_app_template”. Already it occupies 246.2 KB.
   1. Since only Peripheral, whether can I optimize by disabling some macros. 246.2KB Flash for Peripheral is bit huge.
   2. To my understanding I cannot cross 256KB as remaining 256KB is use for Image up-gradation.
2. For time being I am planning to use “System ON” low power mode. Whether can I use RTC timer for this. Any reference for using RTC as “System ON” mode ?
3. For I2C & SPI interface do I need to add files from Peripheral example code. My worry is difference between SoftDevice Enabled/Disable example code. Whether can I add those files directly into 'ble_app_template' project.
4. Other than “ble_app_template”, is there any other better application to meet my above requirements or this should be fine ?

Please let me know your thoughts.

Thanks & Regards

If you're taking that from SES, I think it includes the SoftDevice.

Yes, the Template does include a load of stuff like bonding, peer manager, etc - which you could do without.

Look at the other peripheral examples, and see which comes close to your requirements.

In particular, the Blinky & Nordic UART ...

Hi,

Thank you for your inputs. Please let me know inputs on 

1) How about Image up-gradation or DFU feature is supported in all BLE Peripheral examples.

and my previous queries.

1. For time being I am planning to use “System ON” low power mode. Whether can I use RTC timer for this. Any reference for using RTC as “System ON” mode ?
2. For I2C & SPI interface do I need to add files from Peripheral example code. My worry is difference between SoftDevice Enabled/Disable example code. Whether can I add those files directly into 'ble_app_template' project.
