Methods and apparatus to control communication data rates of low-energy devices

A non-transitory computer readable storage medium comprising instructions that, when executed, cause at least one processor of a network bridge of a field device in a process control environment to at least:

• determine a first charging rate of a power supply based on first data in a data buffer, the field device to write the first data to the data buffer;
• determine a power budget associated with the BLE radio based on the first charging rate;
• adjust the power budget in response to a change of the first charging rate to a second charging rate, the change to the second charging rate in response to a write by the field device of second data to the data buffer, the second charging rate different from the first charging rate, the second data different from the first data;
• determine whether to divide a first computation task into at least a second computation task and a third computation task based on (1) power budget and (2) at least one of the first charging rate or the second charging rate of the power supply;
• and
• in response to a determination to divide the first computation task, after the first computation task is to be executed by the BLE radio:
• instruct the BLE radio to enter a sleep mode after the second computation task is executed;
• and
• invoke the BLE radio to transition from the sleep mode to an operating mode to execute the third computation task, the invocation in response to a measurement associated with the power supply satisfying a power budget threshold.
