Hi everyone!
I have a nRF52840 dongle and I am trying to run python examples from pc-ble-driver-py. The dongle is connected to a PC running Ubuntu 18.04. The dongle is flashed by the Bluetooth Low Energy Software (2.3.1) with the following firmware:
Connectivity firmware version: ble-connectivity 4.1.1+May-07-2019-15-12-18. SoftDevice API version: 3. Baud rate: 1000000.
Following the instructions from nordic gitgub, python wrapper is only compiled for API version 2 and version 5, while the firmware is for API version 3. When I try to run c examples from pc-ble-driver it only works with version 3 of the following :
heart_rate_collector_sd_api_v2
heart_rate_collector_sd_api_v3
heart_rate_collector_sd_api_v5
heart_rate_collector_sd_api_v6
heart_rate_monitor_sd_api_v2
heart_rate_monitor_sd_api_v3
heart_rate_monitor_sd_api_v5
heart_rate_monitor_sd_api_v6
Running python (3.7) program heart_rate_collector.py will result in the failure shown below. My question is how I can run python applications to communicate with nRF52840 dongle (PCA10059)? Do I need any specific firmware flashed on the dongle?
