Hi, I can't get 250Kbps working on the nRF24LE1. I'm using the enhanced shockburst examples in the nRFgo SDK (enhanced_shockburst_ptx_nrf2 and enhanced_shockburst_prx_nrf2). I added a call to hal_nrf_set_datarate: // Power up radio hal_nrf_set_power_mode(HAL_NRF_PWR_UP); hal_nrf_set_datarate(HAL_NRF_250KBPS); //HAL_NRF_1MBPS, /** Datarate set to 1 Mbps */ //HAL_NRF_2MBPS, /** Datarate set to 2 Mbps */It works fine if I change it to 2Mbps and 1Mbps. I'm changing the data rate at both the transmitter and th...

FreeRTOS with RTT

I am building the ble_app_hrs_freertos example code for a pca10040 dev board located in the SDK 12.2 at: nRF5_SDK_12.1.0_0d23e2a/examples/ble_peripheral/ble_app_hrs_freertosI have the following 2 RTT macros define: Makefile - NRF_LOG_USES_RTT=1 sdk_config.h - NRF_LOG_BACKEND_SERIAL_USES_RTT 1I get the RTT logs through the debugger for a bit and then hit a hard_fault. I have no problems with RTT for non-FreeRTOS builds. Anyone have success with RTT logging within a FreeRTOS build?...

I have tried to build this by double-click on the .xcworkspace file, in the folder obtained from the downloaded .zip (dated Nov 24, 2016), then "Build + Run". I get 203 errors, starting with "EVReflection\EVExtensions.swift "Extraneous "_" in parameter "arr" has no keyword argument name". And on, and on, from there. I don't know Swift, and I wouldn't expect there to be "errors" as basic as this in a released package; it almost seems that some "pr...
