1. An apparatus comprising:
a wirelessly chargeable power source or a power source with energy harvesting capability;
at least one processor and at least one memory, said at least one memory stored with computer program code thereon, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to perform:
receive a configuration message from a network node, said configuration message comprising a first random access (RA) resource and a second RA resource and a threshold value for selecting the first RA resource or the second RA resource based on an energy level of said power source;
obtain data to be transmitted to the network node;
initiate an initial access procedure by sending at least one of the first RA resource or the data to the network node in response to the energy level of said power source being at least at the threshold value;
initiate the initial access procedure by sending the second RA resource to the network node in response to the energy level of said power source being below the threshold value; and
enter, in response to sending the second RA resource, into an energy harvesting mode for charging said power source.
