Hi all,
My HW setup is your colibri imx7 with a custom carrier board where the wifi module is soldered.
I have the same Wifi module (AW-CM276NF) that is on the Colibri imx6 module. I would like to know if you guys know anything about the Transmit power of the bluetooth module.

I am currently using some test scripts to activate a continuous TX mode of the module.wlan_script/bt_ctx.sh at master · hychiang73/wlan_script · GitHub

I measure the output power conducted at the module’s output connector and I only see around -20dBm.

How can I change the output power or put it in such a mode that I get the maximum output of around 4dBm for Bluetooth, I am measuring at the AUX antenna port.

Hello,

Could you provide more information like:

  • Which BSP are you using?
  • What is the connection to AW-CM276NF? SDIO? UART?
  • Are you using the NXP drivers or Marvell/Mainline drivers?

Best regards,
André Curvello
