Host can not write more then 20 bytes data to CC26xx

Hi Kimi,

I need to take a look and reproduce. I'll get back to you.

Hey Kimi,
I'm not fully confident that you have modified the code correctly to achieve the correct data transfer. The attached files does not include any updated definition for characteristic 3, it's still defined as a 1 byte characteristic. To correctly design your prototype, please define characteristic to be 30 bytes in a similar fashion as characteristic 5 is 5 bytes large. The updates should be reflected throughout the simpleGATTprofiles and it's functions to handle characteristic 3.

Let me know if i'm missing something.

Best Regards
Joakim

Hi Joakim,

Thank you for your reply.

I only modify sample code to update receive data length(please check SimpleGATTProfile.c-->simpleProfile_WriteAttrCB()-->case SIMPLEPROFILE_CHAR3_UUID: and SimpleBLEPeripheral.c-->SimpleBLEPeripheral_processCharValueChangeEvt())
I get wrong data length(in my fully test, data is not correct) on CC2650 but on CC2541 is correct

Let me clarify my question. I do the same change on CC2541 and CC2650, but i get different result, why?

thanks

Hi Aslak,

Do you reproduce this issue? any suggetsion?

Hi Joakim & Aslak,

Do you have any update for this problem?

thanks

Hey Yuhua,

Were u able to solve this issue?

Hi Prad,

As I know, this bug was fixed with stack-2.0.0(and later). I test with stack-2.2.1, SimpleBLEPeripheral can receive 25 bytes. You need modify simple_gatt_profile.c to receive data.

Hey Yuhua,

Actually i am able to receive data from mobile/ Dongle to the Device upto 50 Byts but the problem occurs when i want to receive data from one device to another. it just receive one byte data only.
