Thingy91 as a central to ble devices

[Raz_k]

Hey,

Im have a thingy91 and multiple nrf52840 pcbs.

my goal is to make the thing91 a central device that reads data from the nrf52 devices and sends it over to the cloud.

As i understand in the thingy91 the nrf52840 board will act in the BLE section and the nrf9160 will communicate with the cloud.

I am searching for an example that could help me.
Till now i found only the lte_ble_gateway that sounds what i am looking for.
But this example is primarily for thingy52. how can i use for the thingy91? how do i separate the different sections? BLE-nrf52 and LTE-nrf91?

Hey,

I started by using NCS 2.6.0V and i got to the same result, no prints nor connection to nrf cloud.
while searching for the answer on this issue i came across this issue, therefore i wanted to follow his steps.

I tried the serial LTE modem example and i did received prints.

according to serial LTE modem I added this on both prj.conf files:

# General config

CONFIG_LOG=y

CONFIG_LOG_DEFAULT_LEVEL=3

CONFIG_STACK_SENTINEL=y

CONFIG_PICOLIBC_IO_FLOAT=y

CONFIG_RING_BUFFER=y

# Segger RTT

CONFIG_USE_SEGGER_RTT=y

# Where console messages (printk) are output.

# By itself, SLM does not output any.

CONFIG_RTT_CONSOLE=y

CONFIG_UART_CONSOLE=n

# Where SLM logs are output.

CONFIG_LOG_BACKEND_RTT=y

CONFIG_LOG_BACKEND_UART=n

But still there is no log from either the 9160 or the 52840.
by the way in the issue i added, Øyvind, says that the relevant configurations are already in the .conf of each nrf52 and nrf91.

Hi,

You could try to disable uart1 in thingy91 dts files as shown in this pull request (commits) and this ticket.
