Hello infineon community,
I am using a CYBT-343026 bluetooth module and transmiting data with SPP protocol. I have a problem that seems to be due to Bluetooth. It is the first time I am using a bluetooth device in a project and I hope someone can help me.
My configuration is :
- UC<----HCI-PROTOCOL (over UART)----->CYBT-343026<----SPP----->PC
- flow control activated on CYBT-343026
The UC is sending 232 bytes each time the CYBT-343026 is sending TX completed frame and there are 2 different PC softwares.
1) The first PC software is not using a lot of CPU ressources and the transmission in this case is done very fast as you can see below :
ZOOM on interval between two SPP Tx completed frame:
But sometime the transmission is interrupted and the root cause is the SPP TX completed frame is never send by CYBT-343026.
2) The second PC software is using more ressource and the consequence is the data transmission is slower in this case the transmission of data is always perform without error.
Is anyone having a solution to avoid SPP TX completed frame interruption ?
Thank you in advance for your help
Best regards
