We are trying to bringup bluetooth chip in Jetson TK1 and we are facing issues in file transfer. Here is the setup:
WL1835MOD EVM board connected to SD-connector in Jetson TK1.
Bleutooth UART lines are wired to UART2 TX, RX, CTS and RTS lines in the Jetson TK1 GPIO header.
Booted the Jetson board and broughtup the bluetooth using the following command:
hciattach -t 10 -s 115200 /dev/ttyTHS1 texas 3000000 flow; hciconfig hci0 up piscan
I am able to scan the nearby devices and see their MAC addresses. But when I am trying to send files over bluetooth to nearby Linux development PC (through Ubuntu GUI app), the Linux kernel hangs without any warning or crash messages.
Have anybody broughtup any bluetooth device in Tegra K1 and able to send/recevice files successfully?
I have tried wiring up the same Bleutooth EVM to iMX6 processor and able to send/receive files over bluetooth without any issues. (Which means Bluetooth firmware is not an issue).
I am using R21.4 Jetson release package (kernel version - 3.10.40). [In iMX6, 3.10.17 kernel version is used).
