which program to choose to advertise data over BLE ?

[SKV]

Hello Everyone,

I have done I2C communication with Grid Eye sensor (AMG 8832) using twi_master_with_twis_slave (nRF5_SDK_12.3.0_d7731ad) example program. Now i want to transmit the Temperature data over BLE . I am not sure which ble_peripheral example to use to transmit the data ?

Thanks in advance.

Hello,

As of now, it is not possible to have advertising packets longer than 31 bytes. Mohammad Afaneh wrote a blogpost which you can find here, which explains the features of BLE 5 advertising. As it also says, many of these features are not yet available through the Nordic Softdevices. 

 

You can look into scan response, which is described at the end of this Advertising Tutorial.

 

Best regards,

Hello Edvin,

Thank you for replying i was able to send more the 31 bytes of data in the advertisement packet by adding the scan response data in the advertising_init() function . I have one last question i have to make the data to be advertise in real time when there is change in the temperature . Is there is a way to do it in real time ?  If yes can you suggest any.

Thank you,
