CC2640R2F: Not connecting with Android BLE Scanner

HS FAE Germany

Part Number: CC2640R2F

Hello,
I successfully executed the Task 1 of the Zero Project. Terminal output: Advertising

Then in Task 2 I want to connect my Android smartphone to the evm with BLE Scanner App. I could see the evm and can try to connect. It tries to connect (App status: connecting). Terminal output: Connected. Peer adress: 0x727A131B83FO
After some seconds it break up trying to connect. Terminal output: Disconnected / Idel then Advertising

What could be the reason?

SDK: simplelink_cc2640r2_sdk_1_35_00_33

Hi Holger,

What type of Android phone are you using? Do you have another LaunchPad you could try to connect to using the BTool method?

When you receive the GAP_LINK_TERMINATED_EVENT, what is the reason field of the GAP_TerminateLinkReq: software-dl.ti.com/.../group___g_a_p.html

Hello Rachel,
I could establish a connection with the BTool. Still the connection with BLE Scanner failes. I use Samsung Galaxy S5 Neo with Android 6.0.1.

Hi Holger,

There may be an issue that was fixed with the latest Android release. I would recommend updating to Android 7. If updating does not solve your problem, can you send a sniffer log showing this issue?

I have a Samsung S5 neo. I'm not sure if Android 7 is offered on this model yet.

My nexus6 with android version 7.0 can not connect to simple peripheral either(use stack 1_35_00_33). The phone request LL_FEATURE_REQ(0x1F00000000000000) and the cc2640r2f respond with LL_FEATURE_RSP(0x1D00000000000000), then nothing happen.
