CC2541: Develop custom profile on CC2541 to use it with smartphone app

Part Number: CC2541
Other Parts Discussed in Thread: CC2640

Hi!

I'm developing an application with CC2541 and I'm trying to create one profile with customized services and characteristics to read and write values on variables using a smartphone app. At first, I will use one BLE terminal on my phone to access this characteristics. The thing is I'm trying to create the service files ("myService.c and myService.h") using the service generator for cc2640 (https://dev.ti.com/tirex/explore/content/simplelink_academy_cc2640r2sdk_4_30_01_00/modules/blestack/ble_01_custom_profile/ble_01_custom_profile.html) , but It uses a library that cc2541 BLE stack doesn't use that is "icall_ble_api.h". Given that, I want to know if I can take this library from BLE5 stack, or if there is another way to generate this files in an easy way.

Regards,

Bruno.

This cannot be applied to CC2541 as I know. You need to refer to "CC2540 and CC2541Bluetooth® Low Energy Software Developers Guide" / to do it.

Hey Bruno,

As YK mentioned, the Example Service Generator's output won't build on the CC2541 for the reasons you've mentioned.

I would study the code inside the example service generator in parallel with looking at the example SimpleGATTProfile in the CC2541 projects. You can use that profile as a start and copy it over, then modify it to your needs. Section 5.5 of the Developer's Guide (linked above) goes over GATT in depth and should provide you with what you need.
