– the default baud rate change to 115200. The download link says V701 but the file says 702. I note that firmware v703 and v701 are no longer available.Ģ019-02 Firmware version 7.02 now available. I haven’t had time to try though.įirmware download page You can get the how to update guide from the same page (or see below). I emailed Huamao a few times about this a while ago and didn’t get any replies but it looks like they at least addressed the problem. The BT05 & AT09 could receive data from the HM-10 but not the other way round. I never got them to fully work with modules like the BT05 and the AT09. I always had issues using the HM-10 with other modules. Added new function used to support different brand BLE device Add AT+PACK command used to modify data in Advertisement package. If you update from < v700 remember the default UART baud rate changed to 115200.ĪT+READOF ?, used to read long char valueĪT+CO, used to make connection. I have not used any of the 7xx firmwares. The latest firmware is v705 and can be downloaded from Huamao here. The readme in the archive is not up-to-date either, see the one that comes with the firmware download.
Huamao version control looks to be as good as mine….
It does include AT+PACK which was introduced in v702 though. The data sheet in the download shows v606/v701 and is not up-todate it does not include the new AT+READOF command and has the old AT+CO command. The docs zip file is available by clicking on one of the HM-10 images on the Huamao Technology products page or download directly here. The differences are usb pads and a crystal.ġ – with usb pads and the additional crystalĢ – with usb pads without the extra crystalģ – no usb pads but with the additional crystal I thought it was time for a minor update. There have been several firmware updates since this guide was written, as of March 2020 the latest is v707. For the main article I am using modules with firmware 5.49 (regular) except the one I am using for the firmware update guide which started with v5.40 and become 5.47. Since I first posted about the HM-10 the firmware has been updated many times and some of the commands have changed.
