Documentation
How do I set Master role for SPP in classic BT on the BT900?
The Master is the device that initiates the connection as per the classic BT inquiry and paging process. There is no option to configure Master/Slave roles in smartBASIC. However, if the BT900 initiates the connection using the BtcSppConnect(BTA$) command then it can be assumed that it has taken the Master role. The BT900 will have performed the inquiry/page, and the remote device will have performed the inquiry/page scan.
I'm getting different SPP throughput between TX and RX. Is there any setting to improve the RX?
By adjusting the FrameSize and Receive Credit in BTCSPPSETPARAMS API, the throughput will be improved, Detail application note: Application Note - BT900 SPP Throughput Analysis.pdf
Why am I asked to enter legacy pairing code when I am pairing the BT900 with another BT 2.1 or later device? Shouldn't it be simple secure pairing (SPP)?
It is because the “pairing mode” has not been enabled in the smartBASIC application. Please search for “PAIRABLE_ON_STARTUP”, and modify the value to 1 in the sample smartBASIC application.
