The platform I am using is imx8qxp

Linux version 5.10.72
Android11
 Bluetooth module is Ap6275P.

We can send files normally, and the corresponding log is BT_send.txt.

But we were unable to successfully receive the file,After receiving a portion of the files, the progress bar does not change.and the corresponding log is BT_recv.txt.

 

DTS

&lpuart1 {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_lpuart1>;
status = "okay";
 
bluetooth {
compatible = "brcm,bcm4362a2";
pinctrl-0 = <&pinctrl_bt>;
pinctrl-names = "default";
max-speed = <2000000>;

brcm,bt-pcm-int-params = [01 02 00 01 01];
};
};

Seems this is the issue of this BT ship. You may need to consult the company of this wifi/bt chip.

The measured signals of the module are all normal. We used a logic analyzer to capture 3% of the waveform of the received file. It seems that after receiving 3%, RTS did not decrease. Do you have any modifications regarding this phenomenon.
