Anna-b112 Bluetooth module support
Hello Nuttx Community, First i would like to say that i really hope that everybody is doing well! I am sorry that long time i didn't had a chance to contribute anything, but life is moving in a very fast pace for me lately. For our sport Wearable system i am working on integration of a Bluetooth module Anna-B112, it is a very interesting small module. The version which we are using is preflashed with Ublox u-connect software and the module is based on nRF52832 nordic chip. I would like to ask for advice on how exactly to implement a relevant support for this to suit Nuttx architecture because i wish to contribute this port when its done. I am familiar that Nuttx has Bluetooth stack and also support for HCI bluetooth modules, but the difference here is that ANNA-B112 has its stack embedder in the nordic chip and the module is controlled via AT commands through UART, so i am not exactly sure how to implement the driver for this module. To me it looks like it has to bypass the nuttx bluetooth stack (because it already has an embedded one) and directly connect to the application layer, please correct me if i am wrong here. I would really appreciate some insight of how exactly to implement the port to suit Nuttx design and to NOT disrupt in any way the already existing implementations of bluetooth connectivity Thank you in advance! -- Kind regards, Ivan Ucherdzhiev CTO @ Barin Sports Bulgaria
simulation spi driver
Have any friends done gpio simulation spi on Nuttx？

Hi Ivan, Nice to hear news from you! So, you don't to flash NuttX inside Anna-B112, but just want to use it as external BT BLE module, right? In this case you need to enable the "Bluetooth H4 UART" There are some examples on NuttX about how to use it. Also you can opt for using NuttX internal BLE Stack (that derives from an old BLE Stack that Intel integrated on Zephyr and that was released for Arduino/Genuino under BSD License) or you can use the NimBLE stack that is more complete and also have examples on NuttX. Using the internal stack could be more challenging, but it will help to improve our own stack.

Hi Prelude, It is using on boards/arm/sam34/arduino-due What issue are you facing? On 10/13/22, Prelude wrote: > Have any friends done gpio simulation spi on Nuttx？ > > > > >
Re: [RESULT] Release Apache NuttX (Incubating) 11.0.0 [RC2]
Hello Alan and Mike :-) Most of us cyberpunks have this problem with time division between what we want to do and what we have to do :-) Mike, your core work might be a good fundament for other people, when it is in the upstream someone can pick a task in a free moment, and piece by piece it may lead to a working solution.. this will be also a fun / hobby project for me :-) I am also in contact with Hans from BeastieLabs, he did crosscompile Minix to Atari ST on FreeBSD some time ago. Although there is no port, only a build script, this also may be a good starting point for MC68000 crossdevelopment on FreeBSD :-) http://www.beastielabs.net/minix.html http://www.beastielabs.net/crossdev.html Best regards :-) Tomek -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
Re: Anna-b112 Bluetooth module support
Hello Alan, Its good to hear from you too. So, you don't to flash NuttX inside Anna-B112, but just want to use it as external BT BLE module, right? The Anna module is flashed with u-blox connect and we are using it as external ble module, the module has the whole ble stack embedded in the u-box connect and is controlled via AT commands, thats why i am not sure how exactly to port it for Nuttx in a suitable way.

Re: Anna-b112 Bluetooth module support
Hi Ivan, Normally using external BLE modules that follows the HCI H4 is easier than porting to some chip with internal BLE and application in the same chip. You can see how it is done in the sim and also here: boards/arm/stm32/stm32f4discovery/src/stm32_hciuart.c BR, Alan On 10/13/22, Embedded Systems wrote: > Hello Alan, > > Its good to hear from you too. > > So, you don't to flash NuttX inside Anna-B112, but just want to use it > as external BT BLE module, right? > > The Anna module is flashed with u-blox connect and we are using it as > external ble module, the module has the whole ble stack embedded in the > u-box connect and is controlled via AT commands, thats why i am not sure > how exactly to port it for Nuttx in a suitable way. > > Best regars, > Ivan ucherdzhiev > > > На чт, 13.10.2022 г., 18:31 Alan C.
