BLE certified module with programmable MCU

[Yaroooo]

Hi all,

I'm looking for an advice on which module may be suitable to use with my application. What I need is a certified BLE module, with small footprint and really low consumption, that has an embedded MCU fully programmable.

This is because I've an application with a single sensor (analog) and some GPIOs where use a dedicated MCU is too much.

BM70 and BM71 are very good, but seems not programmable.

Any advices?

Today we got a Sensirion gadget that is quite impressive:

The user guide has github links and as far as i have seen, this is a very good starting point including all sources. The BLE module used is a BVMCN5103-BK (Cortex M0). We downloaded the iphone app and it worked perfectly.

Regards, Dieter

did you look at ruuvitag and their dev-kit?

should be fairly open, so I think they have kicad-files for the schematic/pcb available, as well as firmware.

Have you looked at nRF52 SoC modules? I've used the BMD-300 (https://www.rigado.com/bmd-300/) modules before and they work well for BLE projects.

This one is what is nearest to the device I'm looking for. I just wondered if nRF is the only one that allow this (programmable MCU with BLE). My question is related to  create a fast application, since Atmel/Microchip and some other brands with their own IDE makes things easy, with also technical support, Nordic is more tricky to setup and debug.

Or maybe it's only an opinion.

If you want really quick 'n' dirty BLE application development try the Laird BL652 which uses a form of BASIC, you can't really get much simpler IMHO.

I was able to quickly code up a BLE application using the Laird BL652 using SmartBasic.  I connected an accelerometer thru I2C to be used for a tilt sensor for the garage door.  In a few lines, it was able to broadcast and connect with my iPhone up and my target system.  There is also breakout board for the BL652 on Amazon with the module soldered on.  This makes it easy to do prototype work since it can connected to a breadboard compared to having to solder thin wires on the module itself.

Cypress has a number of PSoC BLE modules: https://www.cypress.com/products/ble-bluetooth. You can get DevKits for them as well.
