Thingy:91 and nRF9160

[Tommy]

Hi

I have a few questions as a newbee on Nordi products:

• Can nRF9160 be used as modem via UART in the same way as i.e. Simcom's ?
• Is it possible to run code on the Arm M33 or do i need another processor for sending data to a server ?
• Can nRF9160 Arm M33 run Micropython or is it only the nRF52840 ?
• What is the correct way to upgrade the Thingy:91 firmware? I have tried via nRFCloud and nRF Desktop without any luck. In the Desktop version, the buttons are greyd for erasing and so on even when i'm connected.

Hi

Does nRF9160 support  "AT+CGDATA="PPP",1" ?  i.e PPP

Or what is the equivalent AT command in nRF9160 ?

PPP is not supported, unfortunately.

 

Kind regards,

 That is possible, if you program this application on to your device: https://github.com/NordicPlayground/fw-nrfconnect-nrf/tree/master/samples/nrf9160/serial_lte_modem

Documentation for this sample is available here: http://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/samples/nrf9160/serial_lte_modem/README.html#

So the nRF9160 cannot be used as a modem like Simcom after all then...

Could you do me a favour and compile an hex file for this code:
https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/samples/nrf9160/serial_lte_modem/README.html

I don't have any setup to build myself, but i need this hex :)

I would strongly recommend that you setup the toolchain and compile any samples that you need manually.

If you get stuck somewhere, just ask us in the forum.

Could you elaborate on where you're stuck in the toolchain setup?

 

Note that if you want to flash the serial_lte_modem using the thingy:91 bootloader, you'll have to add these to the prj.conf file (so that it generates the app image for mcuboot):

# MCUBOOT
CONFIG_BOOTLOADER_MCUBOOT=y
CONFIG_IMG_MANAGER=y
CONFIG_MCUBOOT_IMG_MANAGER=y

# Flash
CONFIG_FLASH=y
CONFIG_IMG_ERASE_PROGRESSIVELY=y

 

Then take the app_signed.hex and use nrf programmer to flash it.

 

Kind regards,

Håkon

Ok will try to install toolchain again.

It's stops here:

Our tools support x86 and amd64 architectures only.

Do you have a x86/amd64 setup available?

 

Kind regards,
