how to enable GPIO+SPI mode on ble application

[nk]

Hi,

I am using NCS v2.4.2 and nRF5340DK + nRF21540EK but I can not enable GPIO+SPI mode.

for example, I use nrf/samples/bluetooth/central_and_peripheral_hr application.

I built the following.

west build -p -b nrf5340dk_nrf5340_cpuapp -d build-ble-hrs nrf/samples/bluetooth/central_and_peripheral_hr -- \
-DSHIELD=nrf21540_ek_fwd -Dhci_rpmsg_SHIELD=nrf21540_ek

I checked netcpu config but GPIO+SPI mode was not enabled. I did not modify NCS code.

what should I do?

 

also, I tried to add child/hci_rpmsg.conf and add the folloing in the conf file.

CONFIG_MPSL_FEM_NRF21540_GPIO_SPI=y

I could enable GPIO+SPI mode by the conf file but the following error output.

It seems netcpu side is crushed. Please help me.

1. please let me know your using ncs version. I am using ncs v2.4.1.
2. please comfirm whether 10dbm and 20dgm are controled by 
   BT_HCI_OP_VS_WRITE_TX_POWER_LEVEL command.

Hi Sorry, I had to delete my previous reply as it was wrong.

You need to still use this below

west build -b nrf5340dk_nrf5340_cpuapp -- -DSHIELD=nrf21540ek_fwd -Dhci_ipc_SHIELD=nrf21540ek

I updated ncs version to v2.7.0. I tried your the build way.
but the build was not success.

devicetree error: /home/user/ncs/nrf/boards/shields/nrf21540ek/nrf21540ek_fwd.overlay:16 (column 1): parse error: undefined node label 'gpio_fwd'

I used nrf/samples/bluetooth/peripheral_uart sample.
your env is no problem?

[Susheel Nuguru]

I tried it long ago, but I had no problem running this sample with the command I shown in my previous reply.

it is strange. I re-checked by fresh wsl2 ubuntu22 env. I could not build. what wrong ?
I did not change the following install step.
Installing the nRF Connect SDK (nordicsemi.com)
