MAYA-W1 Bluetooth using Uart

[Da_123456_DA]

Hello,

I'm trying to communicate with my MAYA Bluetooth device

I have connect it to UART9 on my board, setup the device tree correct :

flx4: flexcom@fc018000 {

atmel,flexcom-mode = <ATMEL_FLEXCOM_MODE_USART>;

status = "okay";

uart9: serial@200 {

atmel,use-dma-rx;

atmel,use-dma-tx;

pinctrl-names = "default";

pinctrl-0 = <&pinctrl_flx4_default>;

status = "okay";

};

pinctrl_flx4_default: flx4_uart_default {

pinmux = <PIN_PC28__FLEXCOM4_IO0>,

<PIN_PC29__FLEXCOM4_IO1>;

bias-disable;

};

but still can't see the device when I try to use HCITOOL

2 questions:

1. is the config correct?

2. what should be the MAYA pins to allow BT ?

blt_rst = 0 , blt_wkp = 1 pwr_enable=1, wifi_ble_disable = 0

did I miss something ?

I'm using SAMA5d27 by Microchip running linux4sam 6.1

I'm trying to run MAYA-W1 BT\Wireless device 

after digging I understand I need to upload the firmware to the device after boot, but I can't seem to understand how to do it

when I connect to the UART port of the MAYA (which use for BT) I can see "Heartbeat" of 3 bytes every 1 seconds.

from google I understand it's waiting to firmware to be upload - but I couldn't find how to upload the image .

also I understand that the firmware is used for both BT and WiFi and I can't work only with BT (this is not mention any where...)

so maybe you know this and can help me with the firmware installtion ?

Thanks ,

Thanks for the reply.

I would recommend you to take a look to this webpage in which you will find more information related to the module and EVK.
Regarding the FW, please take a look to the following GitHub repositories in which you will find Wi-Fi Firmware and Wi-Fi Driver.

Regards,

Daniel.

I have done everything it said in the manual

still unable to connect 

just to see I understand correct:

1.The WiFi and the BT work together - there is no only BT firmware ?

2. I must upload to the device the firmware in order to make it work , if I don't do this nothing will work

no BT and no WiFi? so the name "Wifi driver\firmware" is not correct - it should be WiFi&BT firmware?

I think this is confusing .....

3. If I get the "Heartbeat" when I try to connect to the BT using UART - it mean that the device is power, but no firmware is uploaded ?

4. Can it be that the problem is that the SDIO line is not config correct in the Device_Tree? I understand I need to setup the config to support WiFI and not leave it as MMC SDIO ?(this is not written anywhere)

Thanks ,

I’m sorry if I wasn’t clear.

In the FW GitHub I shared with you, in tag lf-6.6.3-1.0.0, if we take IW416 as example and we take a look to the following directory imx-firmware/nxp/FwImage_IW416_SD you will find 3 different firmwares.

The one named “sdiouartiw416_combo_v0.bin” will work for both Wi-Fi and BT. Please notice that SDIO will be used for Wi-Fi and UART for BT.

The other 2 FWs, are specific to each protocol.

In terms of the driver, it is the same for both Wi-Fi and Bluetooth. We name it WLAN driver or Wi-Fi driver though.

I would recommend you to take a look to the Getting Started with NXP-based Wireless Modules on i.MX 8M Quad EVK Running Linux OS. This is available in the IW416 documentation.

Please take a look to the whole document, specially to Section 5 and 6.

Please note this guide is for an i.MX8MQ-EVK running the i.MX Linux BSP. But I really think it will help you to clear out most of your doubts.

Regards,

Daniel.

OK ,
to summarize
if the SDIO line isn't working - I won't be able to load the bin file to the module , and it won't work.
I need to "play" with the device tree until I will see "HIGH SPEED MMC......." connected to the unit

is this correct ?

so , can I ask from you 2 things:
1. send me a working Device_Tree configuration for the SDIO ( I will try to compare with what I have and see what is wrong )
2. show me the "On" status for the device , meaning : what should be on every pin of the module so it will be "Online" and waiting for upload

I want to make sure there is no Hardware \ power issue

Thanks ,

I just tried this with an i.MX 8M Mini EVK running the NXP Linux BSP 6.1.22 using the EVK-MAYA-W161.

I was able to load the drivers and FW correctly, please find my logs:

I have found the problem

now everything is working

Thank you !!!!!!

now I can connect to the BT , publish my name - connect to it

now I need to build the app is needed.

thank you

Hi,

Could you please help me with the following information?

- What host are you using?

- Are you using a custom board?

- What OS version are you using?

- What Wi-Fi FW and driver are you using?

Regards,

Daniel.
