lte_lc_psm_param_set()

int lte_lc_psm_param_set	(	const char *	rptau,
		const char *	rat
	)

#include <include/modem/lte_lc.h>

Set modem PSM parameters.

Requested periodic TAU (RPTAU) and requested active time (RAT) are used when PSM mode is subsequently enabled using lte_lc_psm_req(). These are the requested values and network determines the final values.

For encoding of the variables, see nRF AT Commands Reference Guide, 3GPP 27.007 Ch. 7.38., and 3GPP 24.008 Ch. 10.5.7.4a and Ch. 10.5.7.3.

Parameters

[in]

rptau

Requested periodic TAU as a null-terminated 8 character long bit field string. Set to NULL to use modem's default value. See 3GPP 24.008 Ch. 10.5.7.4a for data format. For example, value of 32400 s is represented as '00101001'. Bits 5 to 1 represent the binary coded timer value that is multiplied by timer unit. Bits 8 to 6 define the timer unit as follows: 000: 10 minutes 001: 1 hour 010: 10 hours 011: 2 seconds 100: 30 seconds 101: 1 minute 110: 320 hours

Parameters

[in]

rat

Requested active time as a null-terminated string. Set to NULL to use modem's default value. See 3GPP 24.008 Ch. 10.5.7.3 for data format. For example, value of 120 s is represented as '00100010'. Bits 5 to 1 represent the binary coded timer value that is multiplied by timer unit. Bits 8 to 6 define the timer unit as follows: 000: 2 seconds 001: 1 minute 010: 6 minutes 111: Timer is deactivated

Return values

0	if successful.
-EINVAL	if an input parameter was invalid.
