Set BLE_6LOWPAN_LEGACY_MODE define for pca10028 for iot sdk 0.8 possible?

[leginox]

Hello everyone,

I'm currently writing my bachelor Thesis and need to establish an iot (preferably mqtt) connection from my pca10028 with my PC as broker (i.e. with mosquitto).

I have two questions regarding this.

1. I already know that iot sdk versions 0.9 and higher do not support pca10028, but is there a workaround?

2. The problem is that for Linux Kernel versions later and onward 4.12 the BLE_6LOWPAN_LEGACY_MODE define in sdk_config.h has to be changed to 0, so that the 6lowpan module is able to decompress packets correctly.

3. So I either need a workaround for higher iot sdk's or the possibility to use an older sdk iot that have the BLE_6LOWPAN_LEGACY_MODE define (iot sdk 0.8 does not have this bit in the config file).

Or maybe someone else already has another solution for that? I appreciate all help and I will provide all information needed.


Best Regards

Hi,

 

Unfortunately, the nRF51-series devices does not have a workaround for this. I would recommend using the nRF52-series devices.

The nRF51-devices are limited in terms of processing power, RAM, and flash for doing (D)TLS, and the SoftDevice S130 does not have a production release that supports connection oriented channels which are required for the IPSP (ie: the bluetooth 6lowpan profile).

nRF52-series Softdevices has connection oriented channels in the production release, and the IoT SDK was merged with the nRF5 SDK from v14.1 and newer.

I strongly recommend using nRF52832 and a production release of the SoftDevice in combination with nRF5 SDK v14.1 (or newer).

 

Kind regards,

Håkon
