SK-TDA4VM: Interface two BLE module

Part Number: SK-TDA4VM
Other Parts Discussed in Thread: TDA4VM

Hello,

I am trying to integrate two bluetooths modules on the sk-tda4vm board. I saw that on the Gpios ports, there were only two TX/RX pins, is it possible to configure other pins to be in TX/RX mode? If yes, how to proceed ?

Thanks in advance for your help!

Thank you very much,
Pierre

If you look at the pinmux options for the TDA4VM, you will see some UARTs available on the pins connected to the expansion header (J3):

TDA4VM pin AC23 (J3 connector pin 12): option for UART0_RXD

TDA4VM pin AG22 (J3 connector pin 35): option for UART0_TXD

TDA4VM pin AF22 (J3 connector pin 38): option for UART1_RXD

TDA4VM pin AJ23 (J3 connector pin 40): option for UART1_TXD

Do we make some configuration to use this pins as TX/RX ?

Second question, do you have a library to communicate with this ports ?

Another question related to pins on SK-tdav4m. Do you know how to install and then include gpio library with ros1 inside robotic_sdk ?

I am looking for created a specific node for bluetooth data reception but i can't include the library. I have follow the instruction here: https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-sk-tda4vm/latest/exports/docs/pi_hdr_programming.htmland install CPP library at: /home/root/ti-gpio-cpp/ But I don't know where I can include this library here: /opt/robotics_sdk/ for ros1.

Do you have any idea ?
