Posted on December 02, 2017 at 01:01The reference manual reads as those pins should be 'w/o pull', however I measure the pins being pulled high during sleep on the bench.The language in the reference manual is confusing (pasted below), because all t...

Posted on November 28, 2017 at 07:28I'm measuring ~1.7mA @ 3V in SLEEPMODE_CPU_HALT and SLEEPMODE_WAKETIMER modes.This is with all peripherals disabled except NVM and SYS_CONTROL.The datasheet indicates:Sleep mode: 32 kHz XO ON (24 KB retention RAM)...

Posted on May 10, 2017 at 08:14Hello,What is the recommended procedure to exit (or disable) LDCR mode for the Spirit1?The documentation has the start up procedure for RX, but no mention of start up for TX or the disable procedure for both.http://www...

Posted on November 30, 2016 at 20:46Hello,Has anyone had success using the Spirit1 library (provided as part of http://www.st.com/en/embedded-software/stsw-connect009.html) in a project for an STM8 MCU using a free toolchain?The library was written...

Posted on November 29, 2017 at 18:46After some more experimentation, it looks like there is a requirement that a HAL virtual timer is set before BlueNRG_Sleep(SLEEPMODE_WAKETIMER, ...) is called and that timer can either be set by the app or the BLE...

Posted on November 29, 2017 at 06:19It looks like calling BlueNRG_Sleep(SLEEPMODE_WAKETIMER, 0, 0), when the BLE stack is idle, does not have the expected result. The BLE stack reports it is okay with SLEEPMODE_NOTIMER when that function is called, ...

Posted on May 15, 2017 at 01:27Investigating this further, it appears that after setting the LDCR mode bit to 0 (disabling LDCR) the SPIRIT1 stays in sleep mode until a READY command is issue.Upon issuing the READY command the SPIRIT1 wakes and then...

Posted on December 02, 2016 at 07:40Thanks Luca,With -pc99 the I get some errors compiling with Cosmic.The following files in the Spirit1 library and example STM8 implementation declare variables in for loops (i.e. ''for(int i = (cDataLength-1); i>=...

On the BlueNRG-1, is it expected that GPIOs 9, 10, and 11 pull high when the device enters sleep?

Can the BlueNRG-1 be put into SLEEPMODE_WAKETIMER when the BLE stack is idle?

Proper sequence to exit LDCR mode for the SPIRIT1?

Compiling Spirit1 library for STM8l152 with a free toolchain?
