CC1350: Sending More than 22 bytes through BLE

Abdelrahman Elborgy

Part Number: CC1350

Hello every body,

i am using CC1350 in BLE mode and actually i have 2 questions:

- first one i was asking, how to send more than 22 bytes through BLE or how to change the "maxLen" in "simpleProfile_ReadAttrCB" from 22 to any other number i want?.

- second one, how can i send data from CC1350 through BLE without any request command from mobile. i mean can i fire that transmission through pin interrupt for example?!!

thanks.

Hi Abdelrahman,

1. You need to use Data Length Extension. Please see the User's Guide:

2. For BLE, you need to use services and characteristics for data transmission. There is no generic "send packet" command that you can use. You can read more about this topic in SimpleLink Academy:

One way of implementing what you describe is to use a pin interrupt to send a notification packet.
