Re: BLE-only power consumption

So been looking at the nrF5x, the BT-12, the HM-13, BlueDuino, BlueFruit, DA14580 instead. I'm sorry if my comment is not seen as constructive, just sharing my experience, no affiliation with Nordic: I've ended up using nRF52832 and mbed OS for the project I originally asked this question for. Quit...

Hi michaelwgnr,

were you able to resolve this issue?

Re: BLE-only power consumption

Totally agree with you, @madscientist_42. What I'm saying is that while the power management is not ready, more hardware means more power consumption, and only the CPU without any radio enabled runs much cooler than when I enable the Bluetooth stack. Still, the duty cycle of CPU tasks should be kept...

Re: BLE-only power consumption

FYI: The BT(LE) drivers in esp-idf as of now aren't optimized for power yet, so while the hardware should support low-power modes, there's no software to use them yet. We're working on getting the needed changes, however. Indeed, the esp-idf is evolving quite fast! Keep up the good work. Meanwhile ...

Re: BLE-only power consumption

Thanks for your answer! As far as I can see in the examples, the only sleep mode currently implemented is the deep sleep mode, which is too costly to wake up from 2-5 times a sec(it's almost a full reset). Also the CPU does not consume that much compared to the radio module (I did some experiments w...

Re: HID Profile

Oh I forgot to add smart TVs. The touchpad remote for my Panasonic is also BLE-based, and it has smaller batteries than the standard IR remote. I was thinking about getting Apple keyboard/trackpad for my MacBook Pro, with the hope that they might work with the TV also. I was experimenting with a gyr...

You'd be surprised at how many are implementing HOGP these days.
If I'm not mistaken, Apple magic keyboards/mice/trackpads all use HOGP. No way a classic BT keyboard would work for several months on a pair of AAs.

BLE-only power consumption

Hi,

Is it possible to implement a battery-powered BLE device with low power consumption right now (a beacon, for example)? I have disabled the Wifi from menuconfig, but the device still heats up while running BLE examples (both esp-idf and Arduino).

If you modify the p_service_uuid parameter to NULL, it works. I know that is not the best solution but to try and play ....
I'm having the same problem, but this workaround doesn't help. Android version is 6.0.1. Another 4.4.4 device can discover services successfully.

gatt server examples

Hi, Has anyone tried running any of the gatt server examples lately(gatt_security_server, gatt_server, gatt_server_service_table)? The advertisement works as expected, but the service discovery fails and the device disconnects. I've tried different Android apps(b-ble, , none of them shows the availa...
