BLE_STATUS_TIMEOUT with terminate_gap_procedure

[GBara.3]

Hi everyone,

I am developing an IOT solution using the BLUENRG-M0 from ST.

I am coding in C and I use a custom board with SPI communication between the BLUENRG and my MSP430F5255 from T.I . I am using the ACI API to transmit commands to the BLE module. 

I have 2 boards, and while one is advertising, I want the other to perform scanning in order to receive an advertising report. (And to get the RSSI after). 

My issue is when I want to make another scan. I use the aci_gap_terminate_gap_procedure() with the good opcode link to the function that I use for scanning, but I always receive a BLE_Timeout error. Therefore my primary scan has not ended correctly and I can’t begin a new one. 

I have tried increasing the time before TIMEOUT but nothing changes. 

I didn’t see people talking about the issue with the gap_terminate function, so I ask this here. 

It would be nice if someone could clarify for me the use of this function and why it has this behavior.  

Best regards.

I have checked the project BlueNRG-MS_New_Chat from the BlueNRG-DK and I saw something strange in it.

 

It is said that Procedure Complete Event proc only when a GAP Terminate is done. So nom I'm a bit confused.

Could you explain me that ? I will share the project here.

I did some tests of my own and the behavior of my scan is really not good. The init goes well but after 5 adertising reports it stops when it should continue until its timeout. I should point out that I have a custom board with an MSP430 processor.

I was able to test a Nucleo64 evaluation board with the IDB05A1 module with the Blue-NRG Gui interface and the scan behavior was normal.

I don't understand what could make the scan behavior change so much, knowing that I'm using the same BlueNRG stack in both cases (x-cube-BLE1).
